3.0.0

Adobe ColdFusion 11 and Lucee 4.5 are no longer supported

Please migrate to a supported engine.

Virtual Inheritance support removed

Virtual Inheritance allowed you to use a quick annotation on your entity instead of extending quick.models.BaseEntity. This was hardly used and didn't offer any benefit to extending using traditional inheritance. Additionally, removing the support allows us to clean up the code base by removing duplicate code paths.

If any of your entities are using the quick annotation, instead have them extends="quick.models.BaseEntity".

`accessors="true"` required for all entities

From the early days of Quick, developers have wanted to have accessors="true" on their entities. Because of this, Quick supported defining entities both with and without accessors. However, just as with virtual inheritance, it created two code paths that could hide bugs and make it hard to follow the code. In Quick 3.0.0, accessors="true" is required on all entities. If it is omitted, a helpful error message is thrown to remind you. This will help immensely in simplifying the code base. (In fact, just introducing this requirement helped find two bugs that were only present when using accessors.)

Ensure all entities have accessors="true" in their component metadata.

AssignedKey removed

Use NullKeyType instead.

Boolean casts updates to hook in to new Cast system

Previously, the only valid cast type was casts="boolean". In introducing the new Casts system, the boolean cast was refactored to use the same system. For this reason, any casts="boolean" needs to be changed to casts="BooleanCast@quick"

defaultGrammar updated to be the full WireBox mapping

In previous versions, the value passed to defaultGrammar was used to look up a mapping in the @qb namespace. This made it difficult to add or use grammars that weren't part of qb. (You could get around this be registering your custom grammar in the @qb namespace, but doing so seemed strange.)

To migrate this code, change your defaultGrammar to be the full WireBox mapping in your moduleSettings:

moduleSettings = {
    "quick": {
        "defaultGrammar": "MSSQLGrammar@qb"
    }
};

HasManyThrough relationship re-tooled to be based on relationships

It no longer accepts any entities or columns. Rather, it accepts an array of relationships to walk "through" to end up at the desired entity.

Here's how the old syntax would be used to define the relationship between Country and Post.

component extends="quick.models.BaseEntity" {

    function posts() {
        return hasManyThrough( "Post", "User", "country_id", "user_id" );
    }
    
}

This same relationship now needs to be defined in terms of other relationships, like so.

component extends="quick.models.BaseEntity" {

    function posts() {
        return hasManyThrough( [ "users", "posts" ] );
    }
    
    function users() {
        return hasMany( "User" );
    }

}

component extends="quick.models.BaseEntity" {

    function posts() {
        return hasMany( "Post" );
    }

}

This approach does require a relationship defined for each level, but it works up and down any number of relationships to get to your desired entity.

`associate` cannot be called on unloaded entities

To update the foreign key of a belongsTo relationship you use the associate method. In the past, it was possible to associate a new, unsaved child entity to its parent using this method.

var newChild = getInstance( "Child" );
newChild.fill( fields );
newChild.parent().associate( parent );
newChild.save();

In an attempt to provide more helpful error messages, this behavior is no longer possible. You can achieve the same effect in one of two ways.

The first is to manually assign the foreign keys:

var newChild = getInstance( "Child" );
newChild.fill( fields );
newChild.setParentKey( parent.getId() );
newChild.save();

While this works, it breaks the encapsulation provided by the relationship.

The second approach is to use the hasOne or hasMany side of the relationship to create the new child entity:

var newChild = getInstance( "Child" );
newChild.fill( fields );
var parent = getInstance( "Parent" ).findOrFail( id );
parent.children().save( newChild );

If you have all the data handy in a struct, you can use the create method for a more concise syntax.

var parent = getInstance( "Parent" ).findOrFail( id );
var newChild = parent.children().create( fields );

This is the recommended way of creating these components.

assignAttributesData argument renamed to `attributes`

This brings the API in line with the other methods referencing attributes.

Method changes due to compound key support

Compound key support required some method and parameter name changes. Although the list seems extensive, you will likely not need to change anything in your code unless you have extended built-in Quick components. (You will see many relationship parameter name changes. Note that the function you call to define a relationship is a function on the BaseEntity and has not changed its signature.)

2.0.0

Quick 2.0 brings with it a lot of changes to make things more flexible and more performant. This shouldn't take too long — maybe 2-5 minutes per entity.

Internal properties renamed

There were some common name clashes between internal Quick properties and custom attributes of your entities (the most common being fullName). All Quick internals have been obfuscated to avoid this situation. If you relied on these properties, please consult the following table below for the new property names.

Additionally, some method names have also changed to avoid clashing with automatically generated getters and setters. Please consult the table below for method changes.

Lastly, the following properties and methods have been removed:

Key Types

Defining Key Types

Key Types are the way to define setting and retrieving a primary key in Quick. In Quick 1.0 these were injected in to the component. This made reusability hard for simple things like sequence names. In order to allow for more flexible key types, key types are no longer injected. Instead, they should be returned from a keyType method.

function keyType() {
    return variables._wirebox.getInstance( "Sequence@quick" )
        .setSequenceName( "seq_users" );
}

The keyType is lazily created and cached on the component, so this is both a more flexible approach as well as being more performant. If you are injecting custom key types in your entities you will need to move them to the method syntax.

Changed Key Types

A few key types have been renamed and will need to be updated in your codebase:

New Key Types

In additional to the changes to defining key types, there is a few new key types introduced in Quick 2.0.

ReturningKeyType

Used with grammars that return their primary key in the query response when inserting to the database. An example of this is NEWSEQUENTIALID in Microsoft SQL Server.

Scopes

The way arguments are passed to scopes have been updated to allow for default arguments. query is still the first argument. Other arguments will be passed in order after that. The args struct is no longer passed.

Relationships

The relationship methods are still named the same but some of the arguments have been changed to fix bugs and support better eager loading performance. Please check the relationship docs for more details.

Additionally, the alternative syntax for defining relationships on a relationships struct has been removed. It created an unnecessary code path that had it's own share of bugs. All relationships should be defined as methods on the entity.

Removing CFCollection

CFCollection was included in Quick 1.0 as both a way to lazily eager load a relationship and as a compatibility layer for older CF versions. The compatibility that CFCollection provides, however, comes with a performance cost. Additionally, the majority of users wanted to use plain arrays as the return format. For those reasons, arrays are now the default return format for collections. CFCollections can still be used by specifying a different return format in the module settings.

Converting to Null

Null is a tricky thing in CFML. The same goes for interacting with nulls in a database. By default, we will support the CFML convention of using an empty string to represent null. When interacting with the database empty strings will be converted to nulls. You can adjust this behavior on the property level with two new annotations:

• convertToNull - Determines if the property will be automatically checked to convert to null at all. Defaults to true.

• nullValue - This is the value that is equivalent to null for this property. Defaults to an empty string.

Returning Null instead of Unloaded Entities

In an effort to avoid dealing with CFML's version of null, Quick originally returned unloaded entities. You could check if an entity was loaded using the isLoaded method. This doesn't make as much sense as null however and even made it more difficult to interact with other libraries. Now Quick will return null when it encounters an empty query result either from a retrieval or from a belongsTo or hasOne relationship. Any instances that you were checking isLoaded should be updated. isLoaded will continue to exist for when you are creating a new entity not from the database.

AutoDiscover Grammar

The default grammar for Quick is now AutoDiscover. This provides a better first run experience. The grammar can still be set in the moduleSettings.

BaseService

As a new way to interact with Quick, you can use Quick Services to interact with your entities in a service-oriented fashion. These are equivalent to VirtualEntityServices in cborm.

The easiest way to use a Quick Service is to use the quickService: injection dsl.

component {
    property name="userService" inject="quickService:User";
}

All methods available on the Quick entity are available on the service.

Eager Loading

Eager loading is now supported for nested relationships using a dot-separated syntax. Additionally, constraints can be added to an eager loaded relationship. See the docs on eager loading for more information.

Column Aliases in Queries

Column aliases can now be used in queries. They will be transformed to columns before executing the query.

Quick entities in Setters

If you pass a Quick entity to a setter method the entity's keyValue value will be passed.

Update and Insert Guards

Columns can be prevented from being inserted or updated using property attributes — insert="false" and update="false".

cbvalidation removed as a default dependency

Quick no longer automatically validates entities before saving them. Having cbvalidation baked in made it hard to extend it. If desired, validation can be added back in using Quick's lifecycle hooks.

instanceReady Lifecycle Method

Quick now announces an instanceReady event after the entity has gone through dependency injected and had its metadata inspected. This can be used to hook in other libraries, like cbvalidation and mementifier.

Automatic Attribute Casting

You can automatically cast a property to a boolean value while retrieving it from the database and back to a bit value when serializing to the database by setting casts="boolean" on the property.

A CFML ORM Engine

Why?

Quick was built out of lessons learned and persistent challenges in developing complex RDBMS applications using built-in Hibernate ORM in CFML.

• Hibernate ORM error messages often obfuscate the actual cause of the error

  because they are provided directly by the Java classes.

• Complex CFML Hibernate ORM applications can consume significant memory and

  processing resources, making them cost-prohibitive and inefficient when used

  in microservices architecture.

• Hibernate ORM is tied to the engine releases. This means that updates come

  infrequently and may be costly for non-OSS engine users.

• Hibernate ORM is built in Java. This limits contributions from CFML

  developers who don't know Java or don't feel comfortable contributing to a

  Java project.

• Hibernate ORM doesn't take advantage of a lot of dynamic- and

  meta-programming available in CFML. (Tools like CBORM have helped to bridge

  this gap.)

We can do better.

What?

Quick is an ORM (Object Relational Mapper) written in CFML for CFML. It provides an ActiveRecord implementation for working with your database. With it you can map database tables to components, create relationships between components, query and manipulate data, and persist all your changes to your database.

Prerequisites

You need the following configured before using Quick:

• Configure a default datasource in your CFML engine

• ColdBox 4.3+

• Add a mapping for quick in your Application.cfc

• Configure your BaseGrammar in config/ColdBox.cfc

See Getting Started for more details.

Supported Databases

Quick supports all databases supported by qb.

Example

Here's a "quick" example to whet your appetite.

We'll show the database structure using a migrations file. This isn't required to use quick, but it is highly recommended.

// 2017_11_10_122835_create_users_table.cfc
component {

    function up() {
        schema.create( "users", function( table ) {
            table.increments( "id" );
            table.string( "username" ).unique();
            table.string( "email" ).unique();
            table.string( "password" );
            table.timestamp( "createdDate" );
            table.timestamp( "updatedDate" );
        } );
    }

}

// User
component extends="quick.models.BaseEntity" {

    // the name of the table is the pluralized version of the model
    // all fields in a table are mapped by default
    // both of these points can be configured on a per-entity basis

}

// handlers/Users.cfc
component {

    // /users/:id
    function show( event, rc, prc ) {
        // this finds the User with an id of 1 and retrieves it
        prc.user = getInstance( "User" ).findOrFail( rc.id );
        event.setView( "users/show" );
    }

}

<!-- views/users/show.cfm -->
<cfoutput>
    <h1>Hi, #prc.user.getUsername()#!</h1>
</cfoutput>

Now that you've seen an example, dig in to what you can do with Quick!

Prior Art, Acknowledgements, and Thanks

Quick is backed by qb. Without qb, there is no Quick.

Quick is inspired heavily by Eloquent in Laravel. Thank you Taylor Otwell and the Laravel community for a great library.

Coming from <cfquery> or queryExecute?

You might be thinking, I don't need an ORM engine. I don't even know what ORM means! I know SQL backwards and forwards so there's nothing an ORM can offer me. Maybe you've had experience with other ORM engines, whether CFML-based or not, and the experience was less that ideal. Why should you consider Quick?

Quick's ORM philosophy comes down to three main points:

1. Give relevant names to important collections of SQL code. (scopes, relationships, etc.)

2. Make queries easy to compose at runtime to get the exact data you want in the most efficient way (subselects, eager loading, etc.)

3. Get out of your way when you need or want to write barebones SQL.

Coming from Hibernate?

Quick was built out of lessons learned and persistent challenges in developing complex RDBMS applications using built-in Hibernate ORM in CFML.

• Hibernate ORM error messages often obfuscate the actual cause of the error

  because they are provided directly by the Java classes.

• Complex CFML Hibernate ORM applications can consume significant memory and

  processing resources, making them cost-prohibitive and inefficient when used

  in microservices architecture.

• Hibernate ORM is tied to the engine releases. This means that updates come

  infrequently and may be costly for non-OSS engine users.

• Hibernate ORM is built in Java. This limits contributions from CFML

  developers who don't know Java or don't feel comfortable contributing to a

  Java project.

• Hibernate ORM doesn't take advantage of a lot of dynamic- and

  meta-programming available in CFML. (Tools like CBORM have helped to bridge

  this gap.)

We can do better.

Configure a default datasource in your CFML engine

You can do this any way you'd like: through the web admin, in Application.cfc, or using cfconfig.

Make sure to set this.datasource in your Application.cfc so Quick knows which datasource to use.

Download Quick

The easiest way to download Quick is to use ForgeBox with CommandBox. Just run the following from the root of your application:

box install quick

Add a mapping for quick in your Application.cfc

For a default installation in a ColdBox template, the following line will do the trick.

this.mappings[ "/quick" ] = COLDBOX_APP_ROOT_PATH & "/modules/quick";

Configure your defaultGrammar in config/ColdBox.cfc

Quick will auto discover your grammar by default on startup. To avoid this check, set a BaseGrammar.

defaultGrammar is a module setting for Quick. Set it in your config/ColdBox.cfc like so:

moduleSettings = {
    quick = {
        defaultGrammar = "MySQLGrammar@qb"
    }
};

Valid options are any of the qb supported grammars. At the time of writing valid grammar options are: MySQLGrammar@qb, PostgresGrammar@qb, MSSQLGrammar@qb and OracleGrammar@qb. You can also have qb discover your grammar on application init using AutoDiscover@qb. Please check the qb docs for additional options.

If you want to use a different datasource and/or grammar for individual entitities you can do so by adding some metadata attributes to your entities.

Relationships are the heart of any ORM engine. They let you interact with relational database tables in an object-oriented way.

Quick's relationship engine provides readable relationship types, extendible relations at runtime, eager loading, and much more.

Start by checking out the different relationship types.

save

New Quick entities can be created and persisted to the database by creating a new entity instance, setting the attributes on the entity, and then calling the save method.

var user = getInstance( "User" );
user.setUsername( "JaneDoe" );
user.setEmail( "jane@example.com" );
user.setPassword( "mypass1234" );
user.save();

When we call save, the record is persisted from the database and the primary key is set to the auto-generated value (if any).

We can shortcut the setters above using a fill method.

fill

Finds the first matching record or creates a new entity.

Sets attributes data from a struct of key / value pairs. This method does the following, in order:

1. Guard against read-only attributes.

2. Attempt to call a relationship setter.

3. Calls custom attribute setters for attributes that exist.

4. Throws an error if an attribute does not exist (if ignoreNonExistentAttributes is false which is the default).

var user = getInstance( "User" );
user.fill( {
    "username": "JaneDoe",
    "email": "jane@example.com",
    "password": "mypass1234"
} );
user.save();

populate

Populate is simply an alias for fill. Use whichever one suits you best.

create

Creates a new entity with the given attributes and then saves the entity.

var user = getInstance( "User" ).create( {
    "username": "JaneDoe",
    "email": "jane@example.com",
    "password": "mypass1234"
} );

There is no need to call save when using the create method.

firstOrNew

Finds the first matching record or returns an unloaded new entity.

var user = getInstance( "User" )
    .firstOrNew( { "username": rc.username } );

firstOrCreate

Finds the first matching record or creates a new entity.

var user = getInstance( "User" )
    .firstOrNew( { "username": rc.username } );

findOrNew

Returns the entity with the id value as the primary key. If no record is found, it returns a new unloaded entity.

var user = getInstance( "User" ).findOrNew(
    9999,
	  {
			  "firstName" : "doesnt",
			  "lastName"  : "exist"
	  }
);

findOrCreate

Returns the entity with the id value as the primary key. If no record is found, it returns a newly created entity.

var user = getInstance( "User" ).findOrCreate(
    9999,
	  {
        "username"  : "doesntexist",
			  "firstName" : "doesnt",
			  "lastName"  : "exist",
			  "password"  : "secret"
	  }
);

updateOrCreate

Updates an existing record or creates a new record with the given attributes.

var user = getInstance( "User" ).updateOrCreate( {
    "username": "newuser"
} );

Hydration Methods

Hydration is a term to describe filling an entity with a struct of data and then marking it as loaded, without doing any database queries. For example, this might be useful when hydrating a user from session data instead of doing a query every request.

hydrate

Hyrdates an entity from a struct of data. Hydrating an entity fills the entity and then marks it as loaded.

If the entity's keys are not included in the struct of data, a MissingHydrationKey is thrown.

var user = getInstance( "User" ).hydrate( {
    "id": 4,
    "username": "JaneDoe",
    "email": "jane@example.com",
    "password": "mypass1234"
} );

user.isLoaded(); // true

hydrateAll

Hydrates a new collection of entities from an array of structs.

var users = getInstance( "User" ).hydrateAll( [
    {
        "id": 3,
        "username": "JohnDoe",
        "email": "john@example.com",
        "password": "mypass4321"
    },
    {
        "id": 4,
        "username": "JaneDoe",
        "email": "jane@example.com",
        "password": "mypass1234"
    }
] );

Once you have an entity and its associated database table you can start retrieving data from your database.

Active Record

You start every interaction with Quick with an instance of an entity. The easiest way to do this is using WireBox. getInstance is available in all handlers by default. WireBox can easily be injected in to any other class you need using inject="wirebox".

Quick is backed by qb, a CFML Query Builder. With this in mind, think of retrieving records for your entities like interacting with qb. For example:

var users = getInstance( "User" ).all();

for ( var user in users ) {
    writeOutput( user.getUsername() );
}

In addition to using for you can utilize the each function on arrays. For example:

var users = getInstance( "User" ).all();

prc.users.each( function( user ) {
    writeOutput( user.getUsername() );
});

You can add constraints to the query just the same as you would using qb directly:

var users = getInstance( "User" )
    .where( "active", 1 )
    .orderByDesc( "username" )
    .limit( 10 )
    .get();

Quick Service

A second way to retrieve results is to use a Quick Service. It is similar to a VirtualEntityService from cborm.

The easiest way to create a Quick Service is to inject it using the quickService: dsl:

component {

    property name="userService" inject="quickService:User"

}

Any method you can call on an entity can be called on the service. A new entity will be used for all calls to a Quick Service.

var users = userService
    .where( "active", 1 )
    .orderByDesc( "username" )
    .limit( 10 )
    .get();

Aggregates

Calling qb's aggregate methods (count, max, etc.) will return the appropriate value instead of an entity or collection of entities.

existsOrFail

Returns true if any entities exist with the configured query. If no entities exist, it throws an EntityNotFound exception.

var doesUserExist = getInstance( "User" )
    .existsOrFail( rc.userID );

Retrieval Methods

all

Retrieves all the records for an entity. Calling all will ignore any non-global constraints on the query.

var users = getInstance( "User" ).all();

get

Executes the configured query, eager loads any relations, and returns the entities in a new collection.

var posts = getInstance( "Post" )
    .whereNotNull( "publishedDate" )
    .get();

paginate

Executes the configured query, eager loads any relations, and returns the entities in the configured qb pagination struct.

var posts = getInstance( "Post" )
    .whereNotNull( "publishedDate" )
    .paginate( rc.page, rc.maxrows );

// default response example
{
    "results": [ User#1, User#2, ... ],
    "pagination": {
        "totalPages": 2,
        "maxRows": 25,
        "offset": 0,
        "page": 1,
        "totalRecords": 40
    }
}

first

Executes the configured query and returns the first entity found. If no entity is found, returns null.

var user = getInstance( "User" )
    .where( "username", rc.username )
    .first();

firstWhere

Adds a basic where clause to the query and returns the first result.

var user = getInstance( "User" )
    .firstWhere( "username", rc.username );

firstOrFail

Executes the configured query and returns the first entity found. If no entity is found, then an EntityNotFound exception is thrown with the given or default error message.

var user = getInstance( "User" )
    .where( "username", rc.username )
    .firstOrFail();

firstOrNew

Finds the first matching record or returns an unloaded new entity.

var user = getInstance( "User" )
    .firstOrNew( { "username": rc.username } );

firstOrCreate

Finds the first matching record or creates a new entity.

var user = getInstance( "User" )
    .firstOrNew( { "username": rc.username } );

find

Returns the entity with the id value as the primary key. If no record is found, it returns null instead.

var user = getInstance( "User" )
    .find( rc.userID );

findOrFail

Returns the entity with the id value as the primary key. If no record is found, it throws an EntityNotFound exception.

var user = getInstance( "User" )
    .findOrFail( rc.userID );

findOrNew

Returns the entity with the id value as the primary key. If no record is found, it returns a new unloaded entity.

var user = getInstance( "User" ).findOrNew(
    9999,
	  {
			  "firstName" : "doesnt",
			  "lastName"  : "exist"
	  }
);

findOrCreate

Returns the entity with the id value as the primary key. If no record is found, it returns a newly created entity.

var user = getInstance( "User" ).findOrCreate(
    9999,
	  {
        "username"  : "doesntexist",
			  "firstName" : "doesnt",
			  "lastName"  : "exist",
			  "password"  : "secret"
	  }
);

Hydration Methods

Hydration is a term to describe filling an entity with a struct of data and then marking it as loaded, without doing any database queries. For example, this might be useful when hydrating a user from session data instead of doing a query every request.

hydrate

Hyrdates an entity from a struct of data. Hydrating an entity fills the entity and then marks it as loaded.

If the entity's keys are not included in the struct of data, a MissingHydrationKey is thrown.

var user = getInstance( "User" ).hydrate( {
    "id": 4,
    "username": "JaneDoe",
    "email": "jane@example.com",
    "password": "mypass1234"
} );

user.isLoaded(); // true

hydrateAll

Hydrates a new collection of entities from an array of structs.

var users = getInstance( "User" ).hydrateAll( [
    {
        "id": 3,
        "username": "JohnDoe",
        "email": "john@example.com",
        "password": "mypass4321"
    },
    {
        "id": 4,
        "username": "JaneDoe",
        "email": "jane@example.com",
        "password": "mypass1234"
    }
] );

Custom Collections

If you would like collections of entities to be returned as something besides an array, you can override the newCollection method. It receives the array of entities. You can return any custom collection you desire.

newCollection

Returns a new collection of the given entities. It is expected to override this method in your entity if you need to specify a different collection to return. You can also call this method with no arguments to get an empty collection.

// Post.cfc
component extends="quick.models.BaseEntity" accessors="true" {

    function newCollection( array entities = [] ) {
        return variables._wirebox.getInstance(
            name = "extras.QuickCollection",
            initArguments = {
                "collection" = arguments.entities
            }
        );
    }

}

To get started with Quick, you need an entity. You start by extending quick.models.BaseEntity.

// User.cfc
component extends="quick.models.BaseEntity" accessors="true" {}

That's all that is needed to get started with Quick. There are a few defaults of Quick worth mentioning here.

Tables

We don't need to tell Quick what table name to use for our entity. By default, Quick uses the pluralized name of the component for the table name. That means for our User entity Quick will assume the table name is users. You can override this by specifying a table metadata attribute on the component.

// User.cfc
component table="my_users" extends="quick.models.BaseEntity" accessors="true" {}

Primary Key

By default, Quick assumes a primary key of id. The name of this key can be configured by setting variables._key in your component.

// User.cfc
component extends="quick.models.BaseEntity" accessors="true" {

    variables._key = "user_id";

}

Quick also assumes a key type that is auto-incrementing. If you would like a different key type, override thekeyType function and return the desired key type from that function.

// User.cfc
component extends="quick.models.BaseEntity" accessors="true" {

    function keyType() {
        return variables._wirebox.getInstance( "UUIDKeyType@quick" );
    }

}

Quick ships with the following key types:

• AutoIncrementingKeyType

• NullKeyType

• ReturningKeyType

• UUIDKeyType

keyType can be any component that adheres to the keyType interface, so feel free to create your own and distribute them via ForgeBox.

interface displayname="KeyType" {

    /**
    * Called to handle any tasks before inserting into the database.
    * Recieves the entity as the only argument.
    */
    public void function preInsert( required entity );

    /**
    * Called to handle any tasks after inserting into the database.
    * Recieves the entity and the queryExecute result as arguments.
    */
    public void function postInsert( required entity, required struct result );

}

Attributes

You specify what attributes are retrieved by adding properties to your component.

// User.cfc
component extends="quick.models.BaseEntity" accessors="true" {

    property name="id";
    property name="username";
    property name="email";

}

Now, only the id, username, and email attributes will be retrieved.

Persistent

To prevent Quick from mapping a property to a database column add the persistent="false" attribute to the property. This is needed mostly when using dependency injection.

// User.cfc
component extends="quick.models.BaseEntity" accessors="true" {

    property name="bcrypt" inject="@BCrypt" persistent="false";

    property name="id";
    property name="username";
    property name="email";

}

Column

If the column name in your table is not the column name you wish to use in Quick, you can specify the column name using the column metadata attribute. The attribute will be available using the name of the attribute.

component extends="quick.models.BaseEntity" accessors="true" {

    property name="id";
    property name="username" column="user_name";
    property name="countryId" column="FK_country_id";

}

Null Values

To work around CFML's lack of null, you can use the nullValue and convertToNull attributes.

nullValue defines the value that is considered null for a attribute. By default it is an empty string. ("")

convertToNull is a flag that, when false, will not try to insert null in to the database. By default this flag is true.

component extends="quick.models.BaseEntity" accessors="true" {

    property name="id";
    property name="number" convertToNull="false";
    property name="title" nullValue="REALLY_NULL";

}

Read Only

The readOnly attribute will prevent setters, updates, and inserts to a attribute when set to true.

component extends="quick.models.BaseEntity" accessors="true" {

    property name="id";
    property name="createdDate" readonly="true";

}

SQL Type

In some cases you will need to specify an exact SQL type for your attribute. Any value set for the sqltype attribute will be used when inserting or updating the attribute in the database. It will also be used when you use the attribute in a where constraint.

component extends="quick.models.BaseEntity" accessors="true" {

    property name="id";
    property name="number" sqltype="cf_sql_varchar";

}

Casts

The casts attribute allows you to use a value in your CFML code as a certain type while being a different type in the database. A common example of this is a boolean which is usually represented as a BIT in the database.

Two casters ship with Quick: BooleanCast@quick and JsonCast@quick. You can add them using those mappings to any applicable columns.

Custom Casts

The casts attribute must point to a WireBox mapping that resolves to a component that implements the quick.models.Casts.CastsAttribute interface. (The implements keyword is optional.) This component defines how to get a value from the database in to the casted value and how to set a casted value back to the database. Below is an example of the built-in BooleanCast, which comes bundled with Quick.

// User.cfc
component extends="quick.models.BaseEntity" accessors="true" {

    property name="id";
    property name="active" casts="BooleanCast@quick";

}

// BooleanCast.cfc
component implements="CastsAttribute" {

	/**
	 * Casts the given value from the database to the target cast type.
	 *
	 * @entity      The entity with the attribute being casted.
	 * @key         The attribute alias name.
	 * @value       The value of the attribute.
	 *
	 * @return      The casted attribute.
	 */
	public any function get(
		required any entity,
		required string key,
		any value
	) {
		return isNull( arguments.value ) ? false : booleanFormat( arguments.value );
	}

	/**
	 * Returns the value to assign to the key before saving to the database.
	 *
	 * @entity      The entity with the attribute being casted.
	 * @key         The attribute alias name.
	 * @value       The value of the attribute.
	 *
	 * @return      The value to save to the database. A struct of values
	 *              can be returned if the cast value affects multiple attributes.
	 */
	public any function set(
		required any entity,
		required string key,
		any value
	) {
		return arguments.value ? 1 : 0;
	}

}

Casted values are lazily loaded and cached for the lifecycle of the component. Only cast values that have been loaded will have set called on them when persisting to the database.

Casts can be composed of multiple fields as well. Take this Address value object, for example:

// Address.cfc
component accessors="true" {

    property name="streetOne";
    property name="streetTwo";
    property name="city";
    property name="state";
    property name="zip";

    function fullStreet() {
        var street = [ getStreetOne(), getStreetTwo() ];
        return street.filter( function( part ) {
            return !isNull( part ) && part != "";
        } ).toList( chr( 10 ) );
    }

    function formatted() {
        return fullStreet() & chr( 10 ) & "#getCity()#, #getState()# #getZip()#";
    }

}

This component is not a Quick entity. Instead it represents a combination of fields stored on our User entity:

component extends="quick.models.BaseEntity" accessors="true" {

    property name="id";
    property name="username";
    property name="firstName" column="first_name";
    property name="lastName" column="last_name";
    property name="password";

    property name="address"
        casts="AddressCast"
        persistent="false"
        getter="false"
        setter="false";
    property name="streetOne";
    property name="streetTwo";
    property name="city";
    property name="state";
    property name="zip";
    
}

Noticed that the casted address is neither persistent nor does it have a getter or setter created for it.

The last piece of the puzzle is our AddressCast component that handles casting the value to and from the native database values:

component implements="quick.models.Casts.CastsAttribute" {

    property name="wirebox" inject="wirebox";

    /**
     * Casts the given value from the database to the target cast type.
     *
     * @entity      The entity with the attribute being casted.
     * @key         The attribute alias name.
     * @value       The value of the attribute.
     * @attributes  The struct of attributes for the entity.
     *
     * @return      The casted attribute.
     */
    public any function get(
        required any entity,
        required string key,
        any value
    ) {
        return wirebox.getInstance( dsl = "Address" )
            .setStreetOne( entity.retrieveAttribute( "streetOne" ) )
            .setStreetTwo( entity.retrieveAttribute( "streetTwo" ) )
            .setCity( entity.retrieveAttribute( "city" ) )
            .setState( entity.retrieveAttribute( "state" ) )
            .setZip( entity.retrieveAttribute( "zip" ) );
    }

    /**
     * Returns the value to assign to the key before saving to the database.
     *
     * @entity      The entity with the attribute being casted.
     * @key         The attribute alias name.
     * @value       The value of the attribute.
     * @attributes  The struct of attributes for the entity.
     *
     * @return      The value to save to the database. A struct of values
     *              can be returned if the cast value affects multiple attributes.
     */
    public any function set(
        required any entity,
        required string key,
        any value
    ) {
        return {
            "streetOne": arguments.value.getStreetOne(),
            "streetTwo": arguments.value.getStreetTwo(),
            "city": arguments.value.getCity(),
            "state": arguments.value.getState(),
            "zip": arguments.value.getZip()
        };
    }

}

You can see that returning a struct of values from the set function assigns multiple attributes from a single cast.

Insert & Update

You can prevent inserting and updating a property by setting the insert or update attribute to false.

component extends="quick.models.BaseEntity" accessors="true" {

    property name="id";
    property name="email" column="email" update="false" insert="true";

}

Formula, Computed, or Subselect properties

Quick handles formula, computed, or subselect properties using query scopes and the addSubselect helper method. Check out the docs in query scopes to learn more.

Multiple datasource support

Quick uses a default datasource and default grammar, as described here. If you are using multiple datasources you can override default datasource by specifying a datasource metadata attribute on the component. If your extra datasource has a different grammar you can override your grammar as well by specifying a grammar attribute.

// User.cfc
component
    datasource="myOtherDatasource"
    grammar="PostgresGrammar@qb"
    extends="quick.models.BaseEntity"
    accessors="true"
{
    // ....
}

At the time of writing Valid grammar options are: MySQLGrammar@qb, PostgresGrammar@qb, SqlServerGrammar@qb and OracleGrammar@qb. Please check the qb docs for additional options.

Comparing Entities

You can compare entities using the isSameAs and isNotSameAs methods. Each method takes another entity and returns true if the two objects represent the same entity.

var userOne = getInstance( "User" ).findOrFail( 1 );
var userTwo = getInstance( "User" ).findOrFail( 1 );

userOne.isSameAs( userTwo ); // true
userOne.isNotSameAs( userTwo ); // false

save

Updates are handled identically to inserts when using the save method. The only difference is that instead of starting with a new entity, we start with an existing entity.

var user = getInstance( "User" ).find( 1 );
user.setPassword( "newpassword" );
user.save();

update

You can update multiple fields at once using the update method. This is similar to the create method for creating new entities.

var user = getInstance( "User" ).find( 1 );
user.update( {
   email = "janedoe2@example.com",
   password = "newpassword"
} );

There is no need to call save when using the update method.

By default, if you have a key in the struct that doesn't match a property in the entity the update method will fail. If you add the optional argument ignoreNonExistentAttributes set to true, those missing keys are ignored. Now you can pass the rc scope from your submitted form directly into the update method and not worry about any other keys in the rc like event that would cause the method to fail.

var user = getInstance( "User" ).find( 1 );
user.update( rc, true );

updateOrCreate

Updates an existing record or creates a new record with the given attributes.

var user = getInstance( "User" ).updateOrCreate( {
    "username": "newuser"
} );

updateAll

Updates matching entities with the given attributes according to the configured query. This is analagous to qb's update method.

getInstance( "User" )
    .where( "lastLoggedIn", ">", dateAdd( "m", 3, now() ) )
    .updateAll( {
        "active" = 0
    } );

fresh

Retrieves a new entity from the database with the same key value as the current entity. Useful for seeing any changes made to the record in the database. This function executes a query.

var user = getInstance( "User" ).findOrFail( rc.userID );
var sameUser = user.fresh();

refresh

Refreshes the attributes data for the entity with data from the database. This differs from fresh in that it operates on the current entity instead of returning a new one. This function executes a query.

var user = getInstance( "User" ).findOrFail( rc.userID );
user.refresh(); // user now has updated data from the database

delete

You can delete an entity by calling the delete method on it.

var user = getInstance( "User" ).find( 1 );
user.delete();

deleteAll

Just like updateAll, you can delete many records from the database by specifying a query with constraints and then calling the deleteAll method.

Deletes matching entities according to the configured query.

getInstance( "User" )
    .whereActive( false )
    .deleteAll();

Additionally, you can pass in an array of ids to deleteAll to delete only those ids. Note that any previously configured constraints will still apply.

getInstance( "User" ).deleteAll( [ 4, 10, 22 ] );

What are Scopes?

Query scopes are a way to encapsulate query constraints in your entities while giving them readable names .

A Practical Example

For instance, let's say that you need to write a report for subscribers to your site. Maybe you track subscribers in a users table with a boolean flag in a subscribed column. Additionally, you want to see the oldest subscribers first. You keep track of when a user subscribed in a subscribedDate column. Your query might look as follows:

var subscribedUsers = getInstance( "User" )
    .where( "subscribed", true )
    .orderBy( "subscribedDate" )
    .get();

Now nothing is wrong with this query. It retrieves the data correctly and you continue on with your day.

Later, you need to retrieve a list of subscribed users for a different part of the site. So, you write a query like this:

var subscribedUsers = getInstance( "User" )
    .where( "subscribed", true )
    .get();

We've duplicated the logic for how to retrieve active users now. If the database representation changed, we'd have to change it in multiple places. For instance, what if instead of keeping track of a boolean flag in the database, we just checked that the subscribedDate column wasn't null?

var subscribedUsers = getInstance( "User" )
    .whereNotNull( "subscribedDate" )
    .get();
