Laravel (Eloquent) query, access scope function from within subquery

Question

I have a scope function for my user table (User.php):

public function scopeWherePaidSubscriber(Builder $query)
{
    return $query->where(....)->where(...);
}

I am trying to access this scope from a subquery looking like this:

$count = UserCalendar::whereIn('user_id', function($que) { 
        $que->select('id')->from('user')->wherePaidSubscriber();
    })->distinct('user_id')->count();

But then I noticed than I couldn't access the scope because I am not using User::wherePaidSubscriber().
The error message looks like the following:

Illuminate/Database/QueryException with message 'SQLSTATE[42S22]: Column not found: 1054 Unknown column 'paid_subscriber'

Eloquent probably tried to find a column named paid_subscriber since it cannot access the scope for the User table.
Is there a way for me to access the scope without having to copy paste it?

Answer 1

Instead of function just pass the data containing the id list of user table as an array.

User::wherePaidSubscriber()->pluck('id')->toArray();
