How to check if a relation was loaded on an Eloquent model already?

Laravel: How to check if a relation was loaded on an Eloquent model already?

Checking if a relation was loaded (maybe by a with() function call when using the Eloquent query builder) is easy.

From inside your model

If you want to do this within your model, you can use $this->relationLoaded():

  1. // from inside your model:
  2. if ($this->relationLoaded("comments")) {
  3.         //..
  4. }
From outside of your model
  1. $user = User::first();
  2. //
  3. if ($user->relationLoaded("comments")) {
  4.   //
  5. }
