获取Laravel中Table的最新记录

Question

I Have a table of projects and reports that reports table save many reports of project in every day. Now, I want to get last reports date property of project I'm using this code in controller:

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

And in view I have this code:

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

But I get this Error: Property [date] does not exist on this collection instance and return $res in view I give this jason:

{"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"}]}

How can I get last reports of any projects?

Answer 1

Assuming your requirement is just to display the latest single record. This below method can be given a shot.

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...you are trying to compare undefined value because the date is part of reports array in your response. So you can't directly access date from your response.Better try to use the below snippet instead of ur blade. It tries to access reports and then access date from reports.

@foreach(Auth::user()->projects as $project)
  @if($res->reports[0]->date == Now())
     <p>hi</p>
 @else
    <p>By</p>
 @endif
@endforeach
