雄辩 - 呼唤未定义的关系

I have a users table and a permissions table. It's a many-to-many relationship so I also have a users_permissions table with a user_id & module_permission_id column.

The user model has the following relationship:

public function permissions()
{
    return $this->belongsToMany(Permission::class, 'users_permissions', 'user_id', 'module_permission_id');
}

When I run my query, the result contains an empty permissions array.

User::with('permissions');

If I echo the query in the with, I get the error: Call to undefined relationship [] on model [App\Models\User]

User::with(['permissions', function($q) {
            echo $q->toSql();  
            die();
        }]);

The rest of the query works, it's just trying to get permissions which is failing.

    Maybe you just forgot the ->get() after User::with('permissions')->get() ?
