Eloquent: Relationships 589
1 $like = App\Like::find(1);
2
3 $likeable = $like->likeable;
The likeable relation on the Like model will return either a Post or Comment instance, depending
on which type of model owns the like.
Custom Polymorphic Types
By default, Laravel will use the fully qualified class name to store the type of the related model.
For instance, given the example above where a Like may belong to a Post or a Comment, the default
likable_type would be either App\Post or App\Comment, respectively. However, you may wish to
decouple your database from your application’s internal structure. In that case, you may define a
relationship “morph map” to instruct Eloquent to use the table name associated with each model
instead of the class name:
1 use Illuminate\Database\Eloquent\Relations\Relation;
2
3 Relation::morphMap([
4 App\Post::class,
5 App\Comment::class,
6 ]);
Or, you may specify a custom string to associate with each model:
1 use Illuminate\Database\Eloquent\Relations\Relation;
2
3 Relation::morphMap([
4 'posts' => App\Post::class,
5 'likes' => App\Like::class,
6 ]);
You may register the morphMap in the boot function of your AppServiceProvider or create a separate
service provider if you wish.
