尝试在Laravel中获取非对象的属性时出错

Question

I'm trying to pass two variables (post and answer) to the question.blade view as I click the "submit" button while storing body, pros, cons in the DB. I receive the following error :

Trying to get property of non-object (View: D:\\wamp\\www\\xxxxxxxxxx\\resources\\views\\Question.blade.php) in 9e68b64a739caa46ec7f5af26c6c40a6cf68ebf3.php line 9 at CompilerEngine->handleViewException(object(ErrorException), '1') in PhpEngine.php line 44

The controller code :

  public function postAnswer(Request $request, $post_id)
        {

          $post = Post::where('id', $post_id)->first();


            $body = $request['body'];
            $pros = $request['pros'];
            $cons = $request['cons'];

            $answer = new Answer();
            $answer->body = $body;
            $answer->pros = $pros;
            $answer->cons = $cons;


    $request->user()->answers()->save($answer);
    $post->answers()->save($answer);

        return view('Question', [
            'post' => $post ,
         'answer' => $answer]);

The question.blade code :

@foreach ($answer as $answers)

                <p>{{ $answers->body }}</p>
                 <p>{{ $answers->pros }}</p>
                  <p>{{ $answers->cons }}</p>

 @endforeach

Answer 1

您正在将$answer作为单个对象发送，但在刀片中将其作为数组使用，或者尝试不使用@foreach在刀片中直接使用它，或者实际上是在尝试发送答案数组，然后发送$request->user()->answers或$post->answers

Answer 2

而不是传递'answer'=> $ answer，您需要传递'answer' => $request->user()->answers()->latest()->first()
