|
* This trait helps a child model (ex: BackpackUser) inherit all relationships of its parent model (ex: User). |
|
10
|
|
|
* Laravel by default doesn't do that, so packages like Backpack\PermissionManager can't see relationships |
|
11
|
|
|
* on the BackpackUser model, because they haven't been inherited from User. |
