Retrieving Entities

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)
.orderBy("username", "desc")
.limit(10)
.get();

For more information on what is possible with qb, check out the qb documentation.

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:

var users = userService
.where("active", 1)
.orderBy("username", "desc")
.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.

Custom Quick Retrieval Methods

There are a few custom retrieval methods for Quick:

all

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

findOrFail & firstOrFail

These two methods will throw a EntityNotFound exception if the query returns no results.

The findOrFail method should be used in place of find, passing an id in to retrieve.

The firstOrFail method should be used in place of first, being called after constraining a query.
