有一个线程，您可以在其中对创建评论功能进行评论，但当我执行更新请求时，它会显示错误：

The subject field is required.
The type field is required.
The thread field is required.

但这与评论无关，而与线程无关。当我检查页面时，链接是这样action="http://127.0.0.1:8000/comment/4"的，而代码中的代码是这样写的，action="{{ route('comment.update', $comment->id) }}" 但不知何故，路由会通过另一种方式到达，thread.update但我不明白为什么，因为当我执行 php artisan "route:list" 时，它会显示路径这是

|        | DELETE    | comment/{comment}       
| comment.destroy     | App\Http\Controllers\CommentController@destroy                         
| web          |
|        | PUT       | comment/{comment}       | comment.update      | 
App\Http\Controllers\CommentController@update                          | web          
|

那么为什么它会通过action="{{ route('threadcomment.store', $thread->id) }}"而不是action="{{ route('comment.update', $comment->id) }}"

网页.php

Route::put('/comment/{comment}','CommentController@update')->name('comment.update');
Route::delete('/comment/{comment}','CommentController@destroy')->name('comment.destroy');

Route::post('/comment/create/{thread}','CommentController@addThreadComment')->name('threadcomment.store');

形式

<div class="comment-list">
    @foreach($thread->comments as $comment)

        <h4>{{$comment->body}}</h4>
        <lead>{{$comment->user->name}}</lead>
