php - Laravel“类型错误 : While Updating Records with PUT/PATCH Methods

Question

当我运行更新 Controller 时，它给了我这个错误，我尝试了来自同一个平台的不同解决方案，但他们的解决方法是使用单独的 save($product) 语法进行更新。我正在使用模型商店进行身份验证和保存数据或编辑删除。

"Type error: Argument 1 passed to Illuminate\Database\Eloquent\Relations\HasOneOrMany::save() must be an instance of Illuminate\Database\Eloquent\Model, array given, called in C:\xampp\htdocs\shopping\app\Http\Controllers\ProductController.php on line 138 ◀"

更新方法

 public function update(Request $request, Product $Product){
      $store = Store::where('user_id', Auth::user()->id)->first();
      $updateProduct = $store->product()->save([
         'name'=> $request->input('name'),
         'description' => $request->input('description'),
         'normal_price' => $request->input('normal_price'),
         'sale_price' => $request->input('sale_price'),
         'category_id' => $request->input('category_id'),
     ]);
         return redirect('product')->with('status', 'Product Updated');
 }

查看编辑表单

 <form method="post" action="{{route('product.update', $product->id)}}">
                                {{ csrf_field() }}
                                {{ method_field('PUT') }}

Answer 1

当您使用 save() 时 Laravel expects model .

使用create() 方法。改变这个:

$updateProduct = $store->product()->save([

收件人:

$updateProduct = $store->product()->create([

或者这样做:

$updateProduct = $store->product()->save(new Product([
    'name'=> $request->input('name'),
    'description' => $request->input('description'),
    'normal_price' => $request->input('normal_price'),
    'sale_price' => $request->input('sale_price'),
    'category_id' => $request->input('category_id'),
]));
