Laravel Route Binding Model Undefined offset：9

问题描述 投票：0回答：1

我正在使用laravel 5.2。我有一个名为Book的模型，然后尝试将路径绑定模型从我的控制器移动到RouteServiceProvider.php

这是我的路由绑定模型，然后我将它移动到RouteServiceProvider.php

$book = Book::findOrFail($id);

之后（在我的RouteServiceProvider.php中）

$router->model('book', 'App\Book');

它在我将它移动到RouteServiceProvider之前完美地工作，但现在它给我一个错误eveytime我尝试更新，（创建和存储工作正常）。

它无法更新数据库的输入，但是当我尝试在请求的规则顶部使用dd($this->method());进行调试时，它会说“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来自条件的补丁/更新方法

这是完整的代码

Controller@update

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',
        ];


    }
}

use Illuminate\Routing\Router;
use Illuminate\Foundation\Support\Providers\RouteServiceProvider as ServiceProvider;

class RouteServiceProvider extends ServiceProvider
{
    /**

     *

    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.
     *

            require app_path('Http/routes.php');
        });
    }
}

您的验证规则先前假定路由段是标识符。现在模型绑定处于活动状态，它将返回模型实例。

$label_rules = 'required|string|size:6|unique:books,label,' . 
                    $this->route()->parameter('book');

这可以在堆栈跟踪中看到。

唯一验证规则支持多个参数，您尝试传入的ID实际上是{"id":15'（第一个逗号之前的数组的初始部分），然后是主键列'judul:"Fast And Furious"'，然后尝试解析其余条目作为额外条件。它们应该成对出现（column,value,column,value,...），但在你的情况下，阵列中只剩下7个条目，数字不均匀。因此失败了。
