Laravel Eloquent缓存查询条件

Question

Here is my UserController@getIndex, it output some users and all user count.

$name = Input::get('name');
$page = Input::get('page');
$limit = Input::get('limit');
$users = User::where('name', 'like', '%'.$name.'%')
        ->orderBy('created_at', 'desc')
        ->skip($limit*$page)->take($limit)
        ->get();

return array(
    'rows'=>$users->toArray(),
    'results'=>User::where('name', 'like', '%'.$name.'%')->count(),
);

Is there any way I can reuse the 'where()' part so I don't have to repeat my self?

Answer 1

You can use query scopes not to repeat yourself:

//app/models/User.php
public function scopeFilterName($query, $name) {
    return $query->where('name', 'like', '%'.$name.'%');
}

///////////////////////////

//in the controller
$name = Input::get('name');
$page = Input::get('page');
$limit = Input::get('limit');
$users = User::filterName($name)
        ->orderBy('created_at', 'desc')
        ->skip($limit*$page)->take($limit)
        ->get();

return array(
    'rows'=>$users->toArray(),
    'results'=>User::filterName($name)->count(),
);
