Description:

Thanks a lot for the amazing work @jessarcher on #43156 .

Am getting an Illuminate\Database\ClassMorphViolationException because I have Relation::enforceMorphMap for some classes. Kindly confirm if this is the desired behavior

Relation::enforceMorphMap([
    'post' => Post::class,
    'video' => Video::class,
]);

It otherwise works perfectly fine when the enforceMorphMap is commented out:

Steps To Reproduce:

• Add Relation::enforceMorphMap(['model'=>'App\Models\Model']) in the boot method of AppServiceProvider and omitting to add \App\Models\User
• Run artisan model:show User

Hi @SamuelMwangiW, I think this is expected. The tokens and notifications relationships on your User model are both MorphMany relationships, so you'd need to specify a morph map for them to work in this scenario. You would get the same exception if you tried to access those relations anywhere else in your application.

If you're not using these relationships, you may consider removing the HasApiTokens and Notifiable traits from the model.

I've confirmed that the exception is not thrown if an "unmapped" model doesn't have any polymorphic relations, so I wouldn't consider this a bug.
