Laravel 10 problem with count scope and paginate method.

Laravel 10 problem with count scope and paginate method.

To answer your question, let's first discuss the context of the problem you're encountering with Laravel 10, count scopes, and the paginate method.

In Laravel, Eloquent ORM provides a convenient way to interact with your database. One common use case is to apply scopes to queries for reusability and readability. A count scope is a type of scope that returns the number of records that match a given query.

However, when using a count scope and the paginate method together, you might encounter some issues. The paginate method returns a paginator object, which includes the total number of records in the result set. When you apply a count scope, Laravel might not correctly calculate the total number of records, leading to incorrect pagination.

Here's a step-by-step guide to help you troubleshoot and resolve the issue:

1. Identify the problem: Check if the issue is indeed related to the count scope and paginate method by reproducing the problem in a simple test case.

class User extends Model
{
    public function scopeCountActiveUsers($query)
    {
        return $query->where('active', true)->count();
    }

    public function scopePaginateActiveUsers($query, $perPage = 15)
    {
        return $query->where('active', true)->paginate($perPage);
    }
}

$users = App\User::countActiveUsers()->paginate(10);

dd($users->total()); // Check if the total is correct

2. Use withCount method: Instead of using a separate count scope, you can use the withCount method to get the total count along with the paginated results.

class User extends Model
{
    public function scopeActiveUsers($query)
    {
        return $query->where('active', true);
    }
}

$users = App\User::activeUsers()->paginate(10);

dd($users->total()); // This should now return the correct total

3. Use a closure: If you still prefer using a count scope, you can use a closure to get the total count before applying the paginate method.

class User extends Model
{
    public function scopeCountActiveUsers($query)
    {
        return $query->where('active', true)->count();
    }

    public function scopePaginateActiveUsers($query, $perPage = 15)
    {
        $total = $query->where('active', true)->count();
        return $query->where('active', true)->paginate($perPage);

        // Alternatively, you can use the following syntax:
        // return $query->where('active', true)->paginate($perPage)->withCount('*');
    }
}

$users = App\User::paginateActiveUsers(10);

dd($users->total()); // This should now return the correct total

By following these steps, you should be able to resolve the issue with count scopes and the paginate method in Laravel 10.
