Eloquent: Relationships 457 the imageable_type column will contain the class name of the owning model. The imageable_type column is how the ORM determines which “type” of owning model to return when accessing the imageable relation. Model Structure Next, let’s examine the model definitions needed to build this relationship: . 1
Eloquent: Relationships 458 . 37 } 38 } Retrieving Polymorphic Relations Once your database table and models are defined, you may access the relationships via your models. For example, to access all of the photos for a staff member, we can simply use the photos dynamic property: . 1 $staff = App\Staff::find(1); 2 3 foreach ($staff->photos as $photo) { 4 // 5 } You may also retrieve the owner of a polymorphic relation from the polymorphic model by accessing the name of the method that performs the call to morphTo. In our case, that is the imageable method on the Photo model. So, we will access that method as a dynamic property: . 1 $photo = App\Photo::find(1); 2 3 $imageable = $photo->imageable; The imageable relation on the Photo model will return either a Staff or Product instance, depending on which type of model owns the photo. Many To Many Polymorphic Relations Table Structure In addition to traditional polymorphic relations, you may also define “many-to-many” polymorphic relations. For example, a blog Post and Video model could share a polymorphic relation to a Tag model. Using a many-to-many polymorphic relation allows you to have a single list of unique tags that are shared across blog posts and videos. First, let’s examine the table structure:
