【问题描述】：
我正在使用 laravel 5.2。我有一个名为 Book 的模型，然后尝试将路由绑定模型从我的控制器移动到 RouteServiceProvider.php
这是我将其移动到 RouteServiceProvider.php 之前的路由绑定模型
$book = Book::findOrFail($id);
之后（在我的 RouteServiceProvider.php 中）
$router->model('book', 'App\Book');
在我将它移动到 RouteServiceProvider 之前它可以正常工作，但现在它每次尝试更新时都会给我一个错误，（创建和存储工作正常）。
它未能更新数据库的输入，但是当我尝试在我的规则顶部使用dd($this->method()); 进行调试时，它显示“PATCH”
错误是Undefined offset: 9 ...framework\src\Illuminate\Validation\Validator.php line 1461: $extra[$segments[$i]] = $segments[$i + 1];
我假设错误来自我的更新控制器 return view('dashboards.book', compact('book')); 或 mybe 来自补丁/更新方法的条件请求
这是完整的代码
控制器@更新
public function update(Book $book, BookRequest $request)
{
//$book = Book::findOrFail($id); move to the RouteServiceProvider
$input = $request->all();
$book->update($request->all());
//return view('dashboards.book');
return view('dashboards.book', compact('book'));
}
BookRequest.php
<?php
namespace App\Http\Requests;
use App\Http\Requests\Request;
class BookRequest extends Request
{
/**
* Determine if the user is authorized to make this request.
*
* @return bool
*/
public function authorize()
{
return true;
}
/**
* Get the validation rules that apply to the request.
*
* @return array
*/
public function rules()
{
//$book = $this->route('book');
//$this->route()->parameter('books');
//dd($this->method());
// Check Create or Update
if ($this->method() == 'POST') {
$label_rules = 'required|string|size:6|unique:books,label,';
$isbn_rules = 'sometimes|string|size:10|unique:books,isbn,';
}
else {
$label_rules = 'required|string|size:6|unique:books,label,' .$this->route()->parameter('book');
$isbn_rules = 'sometimes|string|size:10|unique:books,isbn,' .$this->route()->parameter('book');
}
return [
'judul' => 'required|string|max:100',
'label' => $label_rules,
'isbn' => $isbn_rules,
'tanggal_terbit' => 'required|date',
'status' => 'required|in:tersedia,dipinjam,hilang,rusak',
'id_penulis' => 'required',
'id_penerbit' => 'required',
'id_kategori' => 'required',
];
}
}
RouteServiceProvider.php
<?php
namespace App\Providers;
use Illuminate\Routing\Router;
use Illuminate\Foundation\Support\Providers\RouteServiceProvider as ServiceProvider;
class RouteServiceProvider extends ServiceProvider
{
/**
* This namespace is applied to the controller routes in your routes file.
*
* In addition, it is set as the URL generator's root namespace.
*
* @var string
*/
protected $namespace = 'App\Http\Controllers';
/**
* Define your route model bindings, pattern filters, etc.
*
* @param \Illuminate\Routing\Router $router
* @return void
*/
public function boot(Router $router)
{
//
parent::boot($router);
// route model binding
$router->model('book', 'App\Book');
}
/**
* Define the routes for the application.
*
* @param \Illuminate\Routing\Router $router
* @return void
*/
public function map(Router $router)
{
$router->group(['namespace' => $this->namespace], function ($router) {
require app_path('Http/routes.php');
});
}
}

对错误有什么建议吗？
【问题讨论】：
-
您能否向我们提供问题的完整堆栈跟踪？
-
@sisve 您好，感谢您的回复，请查看我的问题更新
-
为什么您的 $label_rules 和 $isbn_rules 在帖子中以逗号结尾？
$this->route()->parameter('book')可能会返回带有模型绑定的 Book 实例，而不是特定的 id。 -
我不确定，也许我在将控制器移动到 BookRequest 之前从控制器复制了规则。参考 laravel 文档 Forcing A Unique Rule To Ignore A Given ID: "'email' => 'unique:users,email_address,'.$user->id"。顺便说一句，我试图删除昏迷，但我把我扔到另一个错误
SQLSTATE[HY093]: Invalid parameter number..
