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

What you're after is not hasManyThrough, but morphedByMany.

hasManyThrough is useful when you have A one-to-many B, B one-to-many C, and you want to use A to fetch many C.

What you have is a polymorphic pivot table sitting in the middle between A and C.

// Topic Model

public function users()
{
    return $this->morphedByMany('App\User', 'subscribable', 'pivot/subscriber_table_name');
}
