Laravel Polymorphic Relations Has Many Through

Question

I have a Subscriber Model

// Subscriber Model

id
user_id
subscribable_id
subscribable_type

public function user()
{
    return $this->belongsTo(\'App\\U         


        

Answer 1

// Topic Model

public function users()
{
    return $this->hasManyThrough('App\User', 'App\Subscriber', 'subscribable_id')->where('subscribable_type', array_search(static::class, Relation::morphMap()) ?: static::class);
}

Polymorphic hasManyThrough relationships are the same as any others, but with an added constraint on the subscribable_type, which can be retrieved from the Relation::morphMap() array, or by using the class name directly.
