laravel blade foreach fetching related tasks to projects 'Trying to get property of non-object'

问题

Hi I am trying to output all the related tasks to a Project but I am getting 'Trying to get property of non-object' in my error log so I'm not sure what I am doing wrong, does anyone have any ideas?

This is my view which has the foreach

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

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

This is my repository which performs the query

public function getProjectTasks($project_id) {

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

and this is my controller:

public function projectrelatedtasks($project_id)
    {

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

but I get this error:

Next exception 'ErrorException' with message 'Trying to get property of non-object (View: /media/sf_Sites/tempus/app/views/projects/projectrelatedtasks.blade.php)' in /media/sf_Sites/tempus/app/storage/views/6e987b895513269a7fde1cd2f82fc6a1:12

Does anyone know how I can construct this foreach to fetch all the related tasks to a project?

回答1:

Your for loop is wrong. It should be

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

Your are looping through all the tasks so the second argument in the foreach is the task itself.
