1(当我试图在控制器的更新功能中使用Model时，我得到了错误？这可能是什么原因。我得到错误：非静态方法Illuminate\Database\Eloquent\Model:：update((不应静态调用
2( 另一个问题是我的删除功能不会删除产品。它重定向到另一个页面。路线上可能有什么错误？
ProductController.php

型号：Product.php
<?php

use IlluminateDatabaseEloquentFactoriesHasFactory;
use IlluminateDatabaseEloquentModel;
class Product extends Model
{
//protected $guarded = [];
protected $fillable = ['title', 'type', 'firstname', 'surname', 'price', 'papl'];
//use HasFactory;
}
删除路线：
Route::delete('/products/{id}',[ProductController::class, 'delete'])->name('deleteProduct');
deleteProduct.blade.php
@extends('layouts/masterlayout')
@section('title', 'All Products')
@section('mainbody')
<form method = "POST" action="../../products/{{$product->id}}">
@csrf
@method('DELETE')
