Model query helper method creation

static method

class Todo extends Model
{
    public static function completed()
    {
        return static::where('isCompleted' , true);
    }
}

App\Todo::completed()->get();
// or
App\Todo::completed()->where('id' '>' 10 )->get();
// or
App\Todo::completed()->find(1);

Scope prefix

Scopes allow you to easily re-use query logic in your models. To define a scope, simply prefix a model method with scope:

class Todo extends Model
{
    public static function scopeInCompleted($query)
    {
        return $query->where('isCompleted' , false);
    }
}

App\Todo::incompleted()->get();
// or
App\Todo::incompleted()->where('id' '>' 10 )->get();
// or
App\Todo::incompleted()->find(1);
