路由模型绑定不起作用 [英] Route Model Binding not working

问题描述

我正在尝试将路由模型绑定用于简单的 CRUD，但更新和删除功能不起作用.我正在使用 laravel 5.5

I'm trying to use Route Model Binding for Simple CRUD but Update And Delete Function Not Working. and I'm Using laravel 5.5

Route::resource('admin/file','AdminController');

我的编辑和删除按钮视图

My View For Edit and Delete Buttons

<a href="{{ route('file.edit', ['id'=>$file->id]) }}">

<form action="{{ route('file.destroy', ['id'=>$file->id]) }}" method="post">
   {{method_field('DELETE')}}
   {{csrf_field()}}
   <button type="submit" class="delete">delete</button>
</form>

我的资源控制器:

namespace App\Http\Controllers;

use App\Files;
use Illuminate\Http\Request;

商店工作正常

  public function store(Request $request)
{
    $this->validate($request,[
        'title'=>'required',
        'body'=>'required',
        'price'=>'required',
        'linkFile'=>'required',
    ]);

     Files::create($request->all());
    return redirect(route('file.index'));
}

但编辑和删除不起作用

public function edit(Files $files)
{
   return view('admin.edit',compact('files'))->with('title','Edit File');
}

public function destroy(Files $files)
{
    $files->delete();
    return redirect(route('file.index'));
}

我的模型:

protected $table='files';

protected $fillable=[
    'title','body','price','linkFile'
];

当我删除按钮时什么也没有发生并编辑为相同

When I Delete Button Nothing Happens and Edit as Same

如果我在第一列添加 dd($files) 进行编辑和删除功能，那么响应将是 [] 并且句柄没有错误

If I Add dd($files) at First Column for Edit and Delete Function Then Response Will be [] and There's No Error for handle

这里是我的路线列表

有人可以帮忙吗?

推荐答案

终于，2 天后我找到了我的答案，我想在这里为每个可能遇到同样问题的人提供我的答案.

Finally, after 2 days I found my answer and I would like to provide my answer here for everyone who maybe has the same problem.

为了使路由绑定起作用，您应该让类型提示的变量名称与路由段名称匹配，如文档要求:

For route binding to work you should have type-hinted variable names match a route segment name, as the doc required :

例如我的编辑方法

这里是我要编辑的路由 URI

Here my route URI for edit

admin/file/{file}/edit

如您所见，有 {file} 参数或您调用的任何内容现在只需要在函数参数中准确地写$file

As you can see there is {file} parameter or anything you call now just need write exactly $file in function parameter

public function edit(Files $file)
{
   return view('admin.edit',compact('file'));
}
