Laravel | Don't load relations were mentioned in protected $with = [];

[slisarenko]

I have a query:

$users = User::query()->with([‘relation’])->get();

A relation described in User model:

public function relation(): MorphTo
{
    return $this->morphTo(__FUNCTION__, 'object_type', 'object_id');
}

Code: $users->first()->relation could return different models as it’s Polymorphic Relationships, each model could have different Eager Loading by Default.

class Book extends Model
{
    protected $with = ['authors', 'publications'];
}

class Magazine extends Model
{
    protected $with = ['shops'];
}

How to avoid loading these relations were defined in each model in protected $with = [];?

[slisarenko]

Personally for me, this looks similar to a case when we use the morphWith method, but in reverse.
We need to avoid loading relations that are specified in:

framework/src/Illuminate/Database/Eloquent/Model.php

Lines 74 to 79 in 81d8154

	/**
	* The relations to eager load on every query.
	*
	* @var array
	*/
	protected $with = [];

Example:

class Post extends Model
{
    protected $with = ['user'];
}

$comments = Comment::query()
    ->with(['commentable' => function (MorphTo $morphTo) {
        $morphTo->morphWithout([Post::class => ['user']]);
    }])
    ->get();

In this case, we specify that if it's a Post model, we don't need to load the 'user' relation.

$keyType property (defualt 'int') on the model might prevent loading the relations (even if fetched from DB).
I had a situation when I forgot to put 'string' on that type and then the relation was null on the model.
