如何删除laravel 5中的帖子资源？

Question

Laravel 5版

我正在开发一个带有新laravel 5版本的项目,由于某些原因我无法删除帖子,当我按下删除它只是将我重定向到带有id/post/3等id的帖子显示页面,我得到一个空白的白色页面,当我回到索引视图时,我收到了所有帖子,而且还没有删除.以下是我的内容:

发布迁移文件

use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;

class CreatePostsTable extends Migration {

    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('posts', function(Blueprint $table)
        {
            $table->increments('id');
            $table->string('title')->default('');
            $table->string('slug')->default('');
            $table->text('body');
            $table->integer('author_id');
            $table->string('author');
            $table->string('featured_image');
            $table->softDeletes();
            $table->timestamps();
        });
    }


    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::drop('posts');
    }

}

PostsController

use Input;
use Redirect;
use Storage;
use SirTrevorJs;
use STConverter;
use Validator;
use Image;
use Boroughcc\Post;
use Boroughcc\Http\Requests;
use Boroughcc\Http\Controllers\Controller;

use Illuminate\Http\Request;

class PostsController extends Controller {
    /**
     * Display a listing of the resource.
     *
     * @return Response
     */
    public function index()
    {
        $posts = Post::all();
        return view('posts.index', compact('posts'));
    }
    /**
     * Update the specified resource in storage.
     *
     * @param  int  $id
     * @return Response
     */
    public function update(Post $post)
    {
        //
        $this->middleware('auth');
        $input = array_except(Input::all(), '_method');
        $post->update($input);

        return Redirect::route('posts.show', $post->slug)->with('message', 'Post updated.');
    }
    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return Response
     */
    public function destroy(Post $post)
    {
        //
        //$post = Post::findOrFail($id);
        $post->delete();
        if($post->delete()) { 
            return Redirect::route('posts.index')->with('message', 'Post deleted.');
        }
    }

}

据我所知,这是可以的,但我认为它的删除方法正在搞砸所有.在我的路由文件中,我设置了路由资源,php artisan以显示路由,我可以看到这样的销毁路由:

|        | GET|HEAD                       | posts                                                 | posts.index   | Boroughcc\Http\Controllers\PostsController@index                 |            |
|        | GET|HEAD                       | posts/create                                          | posts.create  | Boroughcc\Http\Controllers\PostsController@create                |            |
|        | POST                           | posts                                                 | posts.store   | Boroughcc\Http\Controllers\PostsController@store                 |            |
|        | GET|HEAD                       | posts/{posts}                                         | posts.show    | Boroughcc\Http\Controllers\PostsController@show                  |            |
|        | GET|HEAD                       | posts/{posts}/edit                                    | posts.edit    | Boroughcc\Http\Controllers\PostsController@edit                  |            |
|        | PUT                            | posts/{posts}                                         | posts.update  | Boroughcc\Http\Controllers\PostsController@update                |            |
|        | PATCH                          | posts/{posts}                                         |               | Boroughcc\Http\Controllers\PostsController@update                |            |
|        | DELETE                         | posts/{posts}                                         | posts.destroy | Boroughcc\Http\Controllers\PostsController@destroy

使用删除按钮发布表单

在这里,我有一个简单的按钮,告诉表单从索引列表中删除资源并从表中获取它.

{!! Form::open(array('class' => 'form-inline', 'method' => 'DELETE', 'route' => array('posts.destroy', $post->id))) !!}
                    <li>
                        <img src="{!! $post->featured_image !!}" alt="" />
                        <a href="{{ route('posts.show', $post->id) }}">{{ $post->title }}</a>
                    </li>
                    (
                        {!! link_to_route('posts.edit', 'Edit', array($post->slug), array('class' => 'btn btn-info')) !!},
                        {!! Form::submit('Delete', array('class' => 'btn btn-danger')) !!}
                    )
                {!! Form::close() !!}

我得到的是什么,没有任何帖子被删除.任何答案或指向正确的地方都会很棒.

Answer 1

我不知道如何使用静态类Form,但我几天前只使用HTML代码发现了这个问题.

这不起作用:

<form action="{{ action('Controller@destroy') }}" method="DELETE">
...
</form>

这很好用:

<form action="{{ action('Controller@destroy') }}" method="POST">
    <input type="hidden" name="_method" value="DELETE">
    ...
</form>

Answer 2

您想在此处使用路由模型绑定。

您可以转到文件boot中的方法app/Providers/RouteServiceProvider.php并添加 int：

$router->bind('posts','Boroughcc\Post');

告诉 Laravelposts参数（它在route:list您提供的) should be bound to thePost` 模型中可见（Laravel 默认情况下将使用 id）

或者您可以app/Http/routes.php使用以下方法执行相同操作：

Router::bind('posts','Boroughcc\Post');
