Question

我有一个项目和报告表，报告表每天都会保存很多项目报告。现在，我想获取项目的最后报告日期属性我在控制器中使用此代码：

 $res = Project::with(['reports' => function($query){
            $query->orderBy('updated_at', 'DESC')->first();
        }])->get();
        return view ('home',compact('res'));

在视图中我有这段代码：

@foreach(Auth::user()->projects as $project)
  @if($res->date == Now())
     <p>hi</p>
 @else
    <p>By</p>
@endforeach

但是我得到了这个错误： Property [date] does not exist on this collection instance 并且返回$ res，我给这个杰森：

{"id":51,"user_id":21,"name":"dff","description":"fff","price":4444,"status":0,"darsad":4,"start_time":"1396-08-18","finish_time":"1396-08-29","created_at":"2017-11-19 08:22:39","updated_at":"2017-11-19 08:22:39","reports":[{"id":20,"user_id":21,"project_id":51,"date":"96\/09\/06","description":"vvvv","created_at":"2017-11-27 11:19:43","updated_at":"2017-11-27 11:19:43"}]}

如何获得任何项目的最新报告？

Answer 1

假设您的要求只是显示最新的单条记录。可以给出以下方法。

Controller Snippet：

$res = Project::orderBy('updated_at', 'DESC')->get();
return view ('home',compact('res'));

Blade Snippet：

    @foreach ($res as $data)
        @if ($loop->first)
            @if($data->reports[0]->date == Now())
              <p>hi</p>
            @else
              <p>By</p>
            @endif

        @endif
    @endforeach

Hayy ...您正在尝试比较未定义的值，因为日期是您的响应中的reports数组的一部分。因此，您无法直接从您的回复访问日期。请尝试使用以下代码段而不是您的刀片。它尝试访问报告，然后从报告中访问日期。

<ion-header>
<!-- header html -->
</ion-header>

<ion-content padding>

  <form-base [formInputs]="formService.formInputs"></form-base>

</ion-content>
