Retrieving Relationships

Relationships can be used in two ways.

The first is as a getter. Calling user.getPosts() will execute the relationship, cache the result, and return it.

var posts = user.getPosts();

The second is as a relationship. Calling user.posts() returns a Relationship instance to retrieve the posts that can be further constrained. A Relationship is backed by qb as well, so feel free to call any qb method to further constrain the relationship.

var newestPosts = user
    .posts()
    .orderBy( "publishedDate", "desc" )
    .get();

You can also call the other Quick fetch methods: first, firstOrFail, find, findOrFail, and firstWhere are all supported. This is especially useful to constrain the entities available to a user by using the user's relationships:

// This will only find posts the user has written.
var post = user.posts().findOrFail( rc.id );

You can also use other Quick fetch methods that provide new entities if a related entity is not found, such as firstOrNew, firstOrCreate, findOrNew, and findOrCreate.

var post = user.posts().firstOrNew( { "title": "First Post" } );

You can also get a new unloaded related entity by calling either the newEntity or the fill functions.

var newPost = user.posts().fill( { "title": "My new post" } );
