Question

我试图在我的dashboard.blade.php上创建一个编辑按钮，我的创建功能可以正常工作。但是编辑给了我“函数App \ Http \ Controllers \ PostsController :: edit（）的参数太少，传递了0且恰好期望了1个”错误...

我查了一下问题，并读到我需要修复Route :: get这样的东西；路线：: get（'/ show / {id}'，'PostsController @ show'）;但是我正在使用Route :: resource（'posts'，'PostsController'）;方法，所以我不确定如何解决此问题？

在这里，dashboard.blade.php

@foreach($posts as $post)
   <tr>
   <td>{{$post->title}}</td>
   <td><a href="/posts/{{$post->id}}/edit" class="btn btn-default">Edit</a></td>
   <td>
      {!!Form::open(['action' =>['PostsController@destroy', $post->id], 'method' => 'POST', 'class' => 'pull-right'])!!}
      {{Form::hidden('_method', 'DELETE')}}
      {{Form::submit('Delete', ['class' => 'btn btn-danger'])}}
      {!!Form::close() !!}
   </td>
   </tr>
   @endforeach

这是我的web.php

Route::get('/', 'PagesController@index');
Route::get('/about', 'PagesController@about');
Route::get('/category/{category}', [ 
    'uses' => 'PostsController@category',
    'as' => 'category'

]);
Route::resource('books', 'BooksController');
Route::resource('posts', 'PostsController');
Route::resource('categories', 'CategoriesController', ['except'=> ['create']]);

Auth::routes();
Route::get('/dashboard', 'DashboardController@index');

这是edit.blade.php

{!! Form::model($post, ['route' => ['PostsController@update', $post->id], 'method' => 'PUT']) !!}
<div class="col-md-4">           
   <div class'form-group'>
      {{ Form::label('title', 'Title')}}
      {{ Form::text('title', $post->title, ['class' => 'form-control', 'placeholder' => 'Title'])}}
   </div>
</div>
<div class="col-md-4">           
  <div class'form-group'>
     {{ Form::label('slug', 'Slug')}}
     {{ Form::text('slug', $post->slug, ['class' => 'form-control ', 'placeholder' => 'Slug', 'required' =>'', 'minlength' => '5', 'maxlength' => '255'])}}
  </div>
</div>
<div class="col-md-4">
     <div class'form-group'>
          {{ Form::label('category_id', 'Category :')}}
          {{ Form::select('category_id', $categories, null, ['class' => 'form-control']) }}
      </div>
 </div>
</div>
<div class="row post_row">
  <div class="col-md-8">
     <div class'form-group'>
          {{ Form::label('body', 'Body')}}
          {!! Form::textarea('body', '$post->body', ['id' => 'article-ckeditor', 'class' => 'form-control space', 'placeholder' => 'Body Text'])!!}
     </div>
  </div>
</div>
<div class'form-group' style="padding-top: 20px">
    {{Form::submit('Submit', ['class'=>'btn btn-primary'])}}
    {!! Form::close() !!}
</div>

不知道您是否需要这个，但是我要添加它

PostsController.php

public function create()
{
  $posts = Post::all();
  $categories = Category::all();

public function edit($id)
{
    $post = Post::find($id);
    $categories = Category::all();
    $cats = array();
        foreach ($categories as $category){
            $cats[$category->id] = $category->title;
            }

    return view('posts.edit')->withPost($post)->withCategories($cats);
}

想看看是否有人可以告诉我解决此问题需要做什么？

函数App \ Http \ Controllers \ PostsController :: edit（）的参数太少，传递了0个且正好是1个
