Question

以下结果是'Undefined property：Illuminate \ Pagination \ Paginator :: $ username'错误。

应该怎么做？无论我看多少次，我似乎都会遇到一些错误（例如受保护的属性和非对象）？

AbsractRepository.php

/**
     * Get Results by Page
     *
     * @param int $page
     * @param int $limit
     * @param array $with
     * @return StdClass Object with $items and $totalItems for pagination
     */
    public function getByPage($page = 1, $limit = 10, $with = array())
    {
        $result             = new StdClass;
        $result->page       = $page;
        $result->limit      = $limit;
        $result->totalItems = 0;
        $result->items      = array();

        $query = $this->make($with);

        $model = $query->skip($limit * ($page - 1))
            ->take($limit)
            ->get();

        $result->totalItems = $this->model->count();
        $result->items      = $model->all();

        return $result;
    }

BaseAdminController.php

/**
 * List resources
 *
 * @return void
*/
public function index()
{ 
    $page = Input::get('page', 1);
    $data = $this->model->getByPage($page, 10);
    $objects = Paginator::make($data->items, $data->totalItems, 10);
    $this->layout->content = View::make($this->namespace . '::admin.index')
        ->with('objects', compact('objects'));
}

index.blade.php

@foreach($objects as $user)
<tr class="">
    <td>{{ $user->username }}</td>
    <td>{{ $user->first_name }} {{ $user->last_name }}</td>
    <td>{{ $user->email }}</td>
    <td class="center">Super Administrator</td>
    <td class="center">YES</td>
    <td class="center"><a href="#"><i class="fa fa-pencil"></i></a></td>
</tr>
@endforeach

Answer 1

问题可能在这里：

$model = $query->skip($limit * ($page - 1))
            ->take($limit)
            ->get();

$result->totalItems = $this->model->count();
$result->items      = $model->all();

$model您使用get()，然后在分配到$result->items时再次使用all()方法。

应该在这里：

$result->items      = $model;

Answer 2

我似乎通过在调用视图时删除了压缩来解决了这个问题。例如，它现在代表：

/**
 * List resources
 *
 * @return void
*/
public function index()
{ 
    $page = Input::get('page', 1);
    $data = $this->model->getByPage($page, 10);
    $objects = Paginator::make($data->items, $data->totalItems, 10);
    $this->layout->content = View::make($this->namespace . '::admin.index')
        ->withObjects($objects);
}

这意味着我现在可以正常运行foreach：

@foreach($objects as $user)
<tr class="">
    <td>{{ $user->username }}</td>
    <td>{{ $user->first_name }} {{ $user->last_name }}</td>
    <td>{{ $user->email }}</td>
    <td class="center">Super Administrator</td>
    <td class="center">YES</td>
    <td class="center"><a href="#"><i class="fa fa-pencil"></i></a></td>
</tr>
@endforeach

这似乎可以解决问题，一切都很好:)
