[FIXED] How to get relationship counts without loading objects in laravel

Issue

I have a model customer and it has many projects. I want to find projects count without including its object.

Customer model includes:

public function numberOfProjects()
{
    return $this->hasMany(Project::class)->count();
}

Query in my controller:

 $customers = Customer::where(['is_active'=>1])
                                ->with(['customerContactInformation'=> function ($query) {
                                    $query->where('is_active',1);
                                }, 'numberOfProjects'])
                                ->skip($skip)->take(10)
                                 ->get();

Its giving me error:Call to a member function addEagerConstraints() on integer

Solution

Try this

Customer Model

public function numberOfProjects()
{
    return $this->hasMany(Project::class);
}

Controller

$customers = Customer::where(['is_active'=>1])
                    ->with(['customerContactInformation'=> function ($query) {
                        $query->where('is_active',1);
                    }])
                    ->withCount('numberOfProjects') //you can get count using this
                    ->skip($skip)
                    ->take(10)
                    ->get();

That should be work

$customers = Customer::withCount('numberOfProjects')->get();

WithCount on the particular status

$customers = Customer::withCount([
                        'numberOfProjects',
                        'numberOfProjects as approved_count' => function ($query) {
                            $query->where('approved', true);
                        }
                    ])
                    ->get();
