Question

我有hasMany个用户和用户belongsTo项目的项目。

我想计算一个项目的用户总数，所以我需要将它们链接起来。

这样我收到Call to undefined method Illuminate\Database\Query\Builder::user()错误。

我做错了什么？

控制器：

class ProjectController extends Controller
{
private $project;

public function __construct(Project $project){

    $this->project = $project;

//        $this->project  = $project
//            ->with('user');
}


public function index(Project $project)
{

    $projects = $project->with('user')->get();

    $currenttime = Carbon::now();

//  return view('project.index', array('projects' => $projects, 'currenttime' => $currenttime));

    return view('user.index', compact('projects'));
}

}

型号user：

public function project(){
    return $this->belongsTo('App\Project', 'project_id','id');
}

型号project：

public function users() {
    return $this->hasMany('App\User', 'id');
}

HTML /刀片：

 @if(isset($projects))

    <table class="table table-striped table-hover table-dynamic datatable">
        <thead>
        <tr>
            <th>{{ trans('common.project') }}</th>
            <th>{{ trans('common.workers') }}</th>
            <th>{{ trans('common.completion_date') }}</th>
            <th>{{ trans('common.status')}}</th>
        </tr>
        </thead>
        <tbody>
        @foreach($projects as $project)
            <tr>
                <td>{!! link_to_route('project.edit', $project->name, [$project->id] )!!}</td>
                <td>{{ $project->id }}</td>
                <td>{{ $project->completion_date }}</td>

                @if (($project->completed) == 1)
                    <td><span class="label label-success">{{ trans('common.completed') }}</span></td>
                @elseif(($project->completion_date) < $currenttime )
                    <td><span class="label label-danger">{{ trans('common.toolate') }}</span></td>
                @elseif(($project->active) == 0)
                    <td><span class="label label-default">{{ trans('common.inactive') }}</span></td>
                @else
                    <td><span class="label label-warning">{{ trans('common.inprogress') }}</span></td>
                @endif

            </tr>
        @endforeach
        </tbody>

    </table>
@endif

您必须提供定义关系的方法名称。我的意思是用户不是用户

public function index(Project $project)
{
$projects = $project->with('users')->get();
$currenttime = Carbon::now();
//  return view('project.index', array('projects' => $projects, 'currenttime' => $currenttime));

return view('user.index', compact('projects'));
}

Laravel 5调用未定义的方法Illuminate \ Database \ Query \ Builder :: method（）
