Ok, So im trying to delete my database based on my database id that i typed onmy browser link(so let say i type product/1),it means i want to delete my my database with id of 1.
好的，所以我试图根据我在浏览器链接上输入的数据库 ID 删除我的数据库（假设我输入 product/1），这意味着我想删除 ID 为 1 的数据库。
What I've achieve so far is that I'm able to show my database based on id i typed but somehow when i want to route the id to my destroy method in ProductController class, it shows that method=>'delete' not allowed,what am i do wrong?
到目前为止，我所取得的成就是，我能够根据我输入的 id 显示我的数据库，但是当我想将 id 路由到 ProductController 类中的 destroy 方法时，它显示不允许 method=>'delete' ，我做错了什么？

Try to use 'laravel data binding'. Add to your RouteServiceProvied.php in boot method following code:
尝试使用“laravel 数据绑定”。在引导方法中添加到您的 RouteServiceProvied.php 以下代码：
$router->model('Product', Product::class);
And change destroymethod at your controller to this:
并将控制器上的destroy方法更改为：
public function destroy(Product $product)
{
$product->delete();
return back();
}
And your route at show.blade.phpfile must be like this:
你在show.blade.php文件中的路由必须是这样的：
'route'=> array('product.destroy', $product),

FORM dont have DELETE method.
FORM 没有 DELETE 方法。
You have to use it like this:
你必须像这样使用它：
In your show.blade.php
在你的 show.blade.php
{!!Form::open([
'method' => 'post',
'route'=> array('product.destroy',$product->id),])!!}
{{ method_field('DELETE') }}
...

I think problem in your case not in delete route. After you delete record in destroymethod, you return redirect to product.showroute which is required parameter id.
So try
我认为您的问题不在删除路线中。在destroy方法中删除记录后，返回重定向到product.show路由，这是必需的参数id。
所以试试
public function destroy($id)
{
$product= Product::where('idoveralRating',$id)
->delete();
return redirect()->route('product.index');
}

Ok i want to answer my own question, the problem in my code is that I'm using a default primary key of which is equal to id(in other word, $primaryKey = 'id'), that's why when i pass my $id to destroy it seems wrong because I pass primary key that doesnt belong to the table, that's why the delete method seems not recognized because of you can't delete something that not exist.
好的，我想回答我自己的问题，我的代码中的问题是我使用的默认主键等于 id（换句话说，$primaryKey = 'id'），这就是为什么当我通过 $ id 销毁它似乎是错误的，因为我传递了不属于该表的主键，这就是为什么 delete 方法似乎无法识别的原因，因为您无法删除不存在的内容。
so the problem is solved with simple step change the primary key,protected $primaryKey='idOveralRating'(for my case, and it works!)
所以通过简单的步骤更改主键解决了问题，受保护的 $primaryKey='idOveralRating'（对于我的情况，它有效！）
