Laravel-分页和get() [英] Laravel - Paginate and get()

问题描述

使用下面的代码，我想要的是对我创建的查询进行分页.但是，当我尝试在获取后添加分页时，会引发错误.我想保持获取，因为我想限制在$ fields上设置的列. 对这个东西进行分页应该是更好的主意吗?还是获取并限制列的好替代方法?

With the code below, what I wanted was paginate the query I created. But, when I try to add paginate after get, it throws an error. I wanted to remain get since I want to limit to columns that was set on $fields. What would should be the better idea to paginate this thing? or what's a good substitute for get and limit the columns?

我尝试过的事情:

->get($this->fields)->paginate($this->limit)

我的控制器的一部分:

class PhonesController extends BaseController {

    protected $limit = 5;
    protected $fields = array('Phones.*','manufacturers.name as manufacturer');
    /**
     * Display a listing of the resource.
     *
     * @return Response
     */
    public function index()
    {



        if (Request::query("str")) {
            $phones = Phone::where("model", 'LIKE', '%'. Request::query('str') . '%')
                        ->join('manufacturers', 'manufacturers_id', '=', 'manufacturers.id')
                        ->get($this->fields);

        } else {
            $phones = Phone::join('manufacturers', 'manufacturers_id', '=', 'manufacturers.id')
                            ->get($this->fields);
        }



        return View::make('phones.index')->with('phones', $phones);
    }

}

推荐答案

如果您查看

If you look at the method signature you will see that paginate receives a second argument, $columns. So your solution would be to use

->paginate($this->limit, $this->fields);

此外，您可以通过稍作更改来清理控制器:

Furthermore, you can clean up your controller by changing things slightly:

public function index()
{

    $query = Phones::join('manufacturers', 'manufacturers_id', '=', 'manufacturers.id');

    if ( Request::query('str') ) {
        $query->where('model', 'LIKE', '%'. Request::query('str') . '%')
    }

    $phones = $query->paginate($this->limit, $this->fields);

    return view('phones.index')->with('phones', $phones);
}
