laravel Blade foreach 将相关任务提取到项目“试图获取非对象的属性”

Question

您好，我正在尝试将所有相关任务输出到项目，但我的错误日志中出现“尝试获取非对象的属性”，所以我不确定我做错了什么，有没有人有任何想法？

这是我的观点，有 foreach

{{ $project->project_name }}
    {{ $project->project_brief }}
    {{ $project->clients->client_name }}

   @foreach ($project->tasks as $project)
    {{ $project->tasks->task_name }}
    @endforeach

这是我执行查询的存储库

public function getProjectTasks($project_id) {

    return \Project::with(['clients', 'tasks'])
        ->whereUserId(Auth::user()->id)
        ->find($project_id);
}

这是我的控制器：

public function projectrelatedtasks($project_id)
    {

    // get the Project tasks
        $project = $this->project->getProjectTasks($project_id);
    return View::make('projects.projectrelatedtasks')
            ->with('project', $project);        
        }

但我收到此错误：

有谁知道我如何构建这个 foreach 来获取项目的所有相关任务？

Answer 1

您的for 循环错误。应该是

@foreach ($project->tasks as $task)
    {{ $task->task_name }}
@endforeach

您正在遍历所有tasks，因此foreach 中的第二个参数是task 本身。
