Laravel 5.5 Update Post无法正常工作

Question

edit.blade.php：

{!! Form::model($post, array('method'=>'PATCH','url'=>'/posts/{post}'.$post->id))  !!}

{{ method_field('PATCH') }}

{{csrf_field()}}

<label for="title">Titolo</label>

<input type="text" class="form-control" id="title" name="title" value="{{$post->title}}">

<label for="body">Corpo</label>

<textarea id="body" name="body" class="form-control" value="{{$post->body}}">

      </textarea>

路由/ web.php：

Route::get('/', 'PostsController@index')->name('home');
Route::get('/posts/create', 'PostsController@create');
Route::post('/posts', 'PostsController@store');
Route::get('/posts/{post}', 'PostsController@show');
Route::get('/posts/tags/{tag}', 'TagsController@index');
Route::post('/posts/{post}/comments','CommentsController@store');
Route::get('/posts/{id}/edit', 'PostsController@edit');
Route::get('/edit/{post}', 'PostsController@update');
Route::patch('/post/{post}', 'PostsController@update');
Route::get('/register', 'RegistrationController@create');
Route::post('/register', 'RegistrationController@store');
Route::get('/login', 'SessionsController@create');
Route::post('/login', 'SessionsController@store');
Route::get('/logout', 'SessionsController@destroy');

postController：

public function edit( Post $post )
{
    return view('posts.edit', compact('post'));
}


public function update(Request $request, Post $post)
{
    Post::where('id', $post)->update($request->all());

    return redirect('/home');
}

Answer 1

您在此处使用model binding，因此请将其更改为：

public function update(Request $request, Post $post){
    $post->update($request->all());
    return redirect('/home');
}

另外，将网址更改为：

'url' => '/posts/' . $post->id

此外，请删除这些字段，因为{!! Form::model() !!}会自动为您插入这些字段：

{{ method_field('PATCH') }}
{{ csrf_field() }}

Answer 2

更改：

select distinct customerId, (
                select StoreCity,
                       TransactionDate,
                       TransactionDescription
                from Temp
                where customerId = T.customerId
                for json path) [JSON]
from Temp T

要

Post::where('id', $post)->update($request->all());

Answer 3

新路线：

Route :: patch（'/ posts / {id} / edit / {post}'，'UpdateController @ update'）;

{!! Form :: model（$ post，array（'method'=＆gt;'POST'，'url'=＆gt;'/ posts / {id} / edit'。$ post-＆gt; id））!!}

我认为/ posts / {id} / edit not working
