Question

我和我的伴侣已经工作了近11个小时的合并时间试图解决这个问题，但我们似乎无法破解它。

我们正在构建一个网络论坛应用程序，用户可以在其中创建自己的主题。我们设法让编辑工作，虽然重定向仍然无法正常工作。我们在http://detune-niuwang.c9users.io/

进行了在线预览

如果您尝试使用“新主题”＆＃39;页面并单击提交按钮，它将只删除键入到表单中的任何内容并在Frontpage上重新检查，不会创建任何线程。编辑功能可用。

以下是我们代码的一些片段：

routes.php文件

Route::resource('posts', 'Channel\Post\Posts');
Route::get('/', 'Channel\Post\Posts@index');

控制器\频道\邮政\ Posts.php

        /**
     * Show the form for creating a new post.
     *
     * @return Response
     */
     public function create()
     {
         return view('posts.create');
     }

     /**
      * Store the newly created post
      *
      * @param PostRequest $request
      * @return Response
      */
      public function store(PostRequest $request)
      {  
          $postData = $this->post->create(['title', 'content']);

          if($this->post->create($postData)) {
              return redirect()->back()->withSuccess('Post successfully created.');
          }
          return redirect()->back()->withError($postData);
      }

create.blade.php

@extends('_shared.master')

@section('title')
Create New Post
@endsection

@section('content')
<div class="panel panel-default">
    <div class="panel-heading">New Thread</div>
    <div class="panel-body">
        {!! Form::open(['route' => 'posts.store', 'class' => 'form-horizontal'])!!}
        @include('posts.form')

对此有任何帮助表示赞赏：）

Eloquent模型上的create方法通常是静态方法。在你的代码中，它似乎被称为实例方法。

我相信你有（至少）3种选择。

将create来电更改为insert来电。（我认为这不会返回Post模型的实例，只是一个布尔值）。
静态调用Post::create($postData);

使用newInstance方法

$post = $this->post->newInstance($postData);
return $post->save() ? $post : null;
