缺少[路由：questions.update]的必需参数，因此在网址中传递了2个参数

如何解决缺少[路由：questions.update]的必需参数，因此在网址中传递了2个参数

伙计，我在文件@Around中的URL中传递两个参数时遇到问题

那是我的错误

我用过

web.php

定义默认路由。

在终端中看起来像：

Route::resource('/exams/{exam}/questions','Backend\QuestionController');

要重定向，它是这样写的

|        | PUT|PATCH | exams/{exam}/questions/{question}      | questions.update   | App\Http\Controllers\Backend\QuestionController@update                 | web        |
|        |           |                                        |                    |                                                                        | auth       |
|        | DELETE    | exams/{exam}/questions/{question}      | questions.destroy  | App\Http\Controllers\Backend\QuestionController@destroy                | web        |
|        |           |                                        |                    |                                                                        | auth       |
|        | GET|HEAD  | exams/{exam}/questions/{question}/edit | questions.edit     | App\Http\Controllers\Backend\QuestionController@edit                   | web        |
|        |           |                                        |                    |                                                                        | auth       |

还有<a href="{{ route('questions.edit',[ $exams->id,$question->id ]) }}"class="btn btn-warning btn-sm"><i class="far fa-edit"></i></a>

Controller.php

但是如果我已经传递了url指示的参数，我不明白为什么它会失败。

还添加编辑视图

 public function edit(Exam $exams,Question $questions,Category $category){
        return view('question.edit',compact( 'exams','questions','category'));
    }

    public function update(QuestionUpdateRequest $request,$id){
        $questions = Question::find($id);
        $questions->description = $request->get('description');
        $questions->iframe = $request->get('iframe');
        $questions->image = $request->get('image');

        $questions->exam_id = $request->get('exam_id');
        $questions->category_id = $request->get('category_id');
        $questions->save();
        return redirect()->route('question.index',$questions->exam_id);
    }

那是你的路线，但是

<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">

<section id="main" class="ui-widget ui-helper-clearfix">

    <div id="left-panel" class="item-list">
        <div class="item-container"></div>  
        <div class="item-container"></div>
        <div class="item-container"></div>
        <div class="item-container"></div>
    </div>

    <div id="right-panel" class="item-list">
        <div class="item-container"></div>
        <div class="item-container"></div>
        <div class="item-container"></div>
        <div class="item-container"></div>
    </div>

</section>

这是您的操作。 您在表单操作中缺少考试ID。

应该是

|        | PUT|PATCH | exams/{exam}/questions/{question}      | questions.update   | App\Http\Controllers\Backend\QuestionController@update                 | web        |
