LARAVEL 9该路由不支持PUT方法.支持的方法:GET、HEAD

Question

我只是得到一个错误，而试图更新数据。我使用post方法，而不是push。我试过添加@method('PUT')，但也不起作用。

创建新类别只是工作得很好，因为它应该做的，但当我试图编辑的东西，它只是抛出错误。我也试着使用route::put，但没有工作。

我CategoryController.php

<?php
namespace AppHttpControllersAdmin;
use AppHttpControllersController;
use AppModelsCategory;
use IlluminateHttpRequest;
class CategoryController extends Controller
{
/**
* Display a listing of the resource.
*
* @return IlluminateHttpResponse
*/
public function index()
{
//
$data = Category::all();
return view('admin.category.index', [
'data' => $data
]);
}
/**
* Show the form for creating a new resource.
*
* @return IlluminateHttpResponse
*/
public function create()
{
return view('admin.category.create');
}
/**
* Store a newly created resource in storage.
*
* @param  IlluminateHttpRequest  $request
* @return IlluminateHttpResponse
*/
public function store(Request $request)
{
$data = new Category;
$data->parent_id = 1;
$data->title = $request->title;
$data->keywords = $request->keywords;
$data->description = $request->description;
$data->status = $request->status;
$data->save();
return redirect('admin/category');
}
/**
* Display the specified resource.
*
* @param  AppModelsCategory  $category
* @return IlluminateHttpResponse
*/
public function show(Category $category)
{
//
}
/**
* Show the form for editing the specified resource.
*
* @param  AppModelsCategory  $category
* @return IlluminateHttpResponse
*/
public function edit(Category $category, $id)
{
//
$data = Category::find($id);
return view('admin.category.edit', [
'data' => $data
]);
}
/**
* Update the specified resource in storage.
*
* @param  IlluminateHttpRequest  $request
* @param  AppModelsCategory  $category
* @return IlluminateHttpResponse
*/
public function update(Request $request, Category $category, $id)
{
//
$data = Category::find($id);
$data->parent_id = 1;
$data->title = $request->title;
$data->keywords = $request->keywords;
$data->description = $request->description;
$data->status = $request->status;
$data->save();
return redirect('admin/category');
}
/**
* Remove the specified resource from storage.
*
* @param  AppModelsCategory  $category
* @return IlluminateHttpResponse
*/
public function destroy(Category $category)
{
//
}
}

我的路线

// Admin category routes
Route::get('/admin/category', [AdminCategoryController::class,'index'] )->name('admin_category');
Route::get('/admin/category/create', [AdminCategoryController::class,'create'] )->name('admin_category_create');
Route::post('/admin/category/store', [AdminCategoryController::class,'store'] )->name('admin_category_store');
Route::get('/admin/category/edit/{id}', [AdminCategoryController::class,'edit'] )->name('admin_category_edit');
Route::post('/admin/category/update/{id}', [AdminCategoryController::class,'edit'] )->name('admin_category_update');

Answer 1

我会对你的代码做这些修改:edit.blade:

<form action="/admin/category/update/{{$data->id}}" method="POST">
@csrf
@method('PUT')
.........

路线:

Route::put('/admin/category/update/{id}', [AdminCategoryController::class,'update'] )->name('admin_category_update');

检查是否有效

还有一件事:如果您正确地创建了模型绑定，那么您的更新函数可能如下所示:

public function update(Request $request, Category $category, $id)
{
//
$category->parent_id = 1;
$category->title = $request->title;
$category->keywords = $request->keywords;
$category->description = $request->description;
$category->status = $request->status;
$category->save();
return redirect('admin/category');
}

这是因为你已经有了模型:public function update(Request $request, **Category $category**, $id)
