Laravel query

It is a wrapper around a particular query. It we need to use a long query again and again then we can create a model inside model like below:

public function scopeIncomplete($query) {

return $query->when(‘is_completed’, 0);

}

Use:

App\Task::incomplete()->get();

District::withCount('ad')->orderBy('ad_count', 'desc')->get();

District has many ad. ad_count is dynamically created property containing total number of add.

class Cars extends Eloquent
{
function photos()
{
return $this->hasMany('Photo')->where('photos.type', '=', 'Cars');
}
}
