Question

Hello其他程序员，我一直在研究订单管理系统。我终于解决了我的所有错误，除了一个我不能出去。一旦我删除了客户或订单，我会收到一条错误消息，提示＆＃34;路由错误＆＃34;。

路由错误没有路由匹配[POST]＆＃34; / customers / 2＆＃34;

Rails.root：/ Users / cecil / Desktop / order_management_systeem

应用程序跟踪|框架跟踪|完整跟踪路径

这是我的路线

           Prefix Verb   URI Pattern                                       Controller#Action

edit_customer_order GET    /customers/:customer_id/orders/:id/edit(.:format) orders#edit
     customer_order GET    /customers/:customer_id/orders/:id(.:format)      orders#show
                    PATCH  /customers/:customer_id/orders/:id(.:format)      orders#update
                    PUT    /customers/:customer_id/orders/:id(.:format)      orders#update
                    DELETE /customers/:customer_id/orders/:id(.:format)      orders#destroy
          customers GET    /customers(.:format)                              customers#index
                    POST   /customers(.:format)                              customers#create
       new_customer GET    /customers/new(.:format)                          customers#new
      edit_customer GET    /customers/:id/edit(.:format)                     customers#edit
           customer GET    /customers/:id(.:format)                          customers#show
                    PATCH  /customers/:id(.:format)                          customers#update
                    PUT    /customers/:id(.:format)                          customers#update
                    DELETE /customers/:id(.:format)                          customers#destroy
                    GET    /:controller/:action/:id/:customer_id(.:format)   :controller#:action

这是我的erb代码

<%= link_to("Delete", customer_path(@customer), method: :delete, confirm: "Are you sure?", :class => 'action delete') %>

销毁控制器

 def destroy
    customer = Customer.find(params[:id]).destroy 
    flash[:notice] = "Subject '#{customer.first_name}' destroyed successfully"
    redirect_to(:action => 'index')
  end

Answer 1

动作破坏应该看起来像以下几行：

def destroy
  @customer = Customer.find(params[:id]
  @customer.destroy
  redirect_to(
    customers_path,
    notice: 'Customer successfully deleted'
  )
end

还编辑链接：

<%= link_to("Delete", @customer, method: :delete, data: { confirm: "Are you sure?" }) %>

您的问题是，您已定义变量customer，但在url_helper（@customer）中使用customer_path(@customer)。

另一件事（更重要的）是，你实际上分配了一个customer一个值，它是从数据库中删除一个对象的结果：

customer = Customer.find(params[:id]).destroy

永远不要这样做。

要么

Customer.find(params[:id]).destroy

或

@customer = Customer.find(params[:id])
@customer.destroy

在轨道上销毁ruby中的客户/订单
