Rails button_to没有路由匹配{：action =>“complete”，：controller =>“dashboard”，：name =>“Order”}

请帮助我尽我所能。 我真的需要你的帮助。

因此，我试图使标记顺序完整。 现在一切都可以通过按钮将订单标记为完成。 我运行了迁移添加。

class AddCompleteToOrder < ActiveRecord::Migration def change add_column :orders, :complete, :boolean, default: false end end 

然后我添加了一个方法order.rb

 def complete! update(complete: true) end 

然后routes.rb

 resources :orders do post "complete", to: "orders#complete", on: :member end 

然后这是按钮

 = button_to "Mark as complete", { action: "complete", id: @order.id } 

但是我没有@ order.id但订单确实有@ order.name所以我把它改成了

 = button_to "Mark as complete", { action: "complete", name: @order.name } 

但后来我得到了错误：

Dashboard中的ActionController :: UrlGenerationError #dadmin显示/Users/jacksharville/Desktop/dancer/app/views/dashboard/dadmin.html.haml，其中第87行引发：

没有路由匹配{：action =>“complete”，：controller =>“dashboard”，：name =>“Order”}

提取的来源（第87行）：85 86 87

 = link_to "Back to Dashboard", :back, :class => 'btn-danger btn' = button_to "Mark as complete", { action: "complete", name: @order.name } 

所以很明显我正在做routes.rb错误，但我无法解决它。 请帮忙。 任何帮助非常感谢。

Answer 1

您可以在button_to标记中指定此附加选项:controller => "order" ，但使用button_to标记的正确方法是不为选项创建单独的哈希。 而是将它用作button_to("Mark as complete", controller: "order", action: "complete", name: @order.name)

Answer 2

试试这个

  button_to "Mark as complete", { controller: "orders", action: "complete", name: @order.name }, {method: :post} 

Answer 3

耙路给我：

 complete_order POST /order/:id/complete(.:format) orders#complete 

Answer 4

您需要将complete操作从DashboardsController移动到OrdersController ，这是在routes文件中定义的位置。

此外，您可以使用：

 = button_to "Mark as complete", complete_order_path(@order) 

控制器动作正在寻找params[:order_id]因此它可以找到正确的顺序。 我不确定您的视图中是如何定义订单的，但您需要将订单对象传递给路径。

如果您在Order类中定义了一个to_param方法，它定义了order的名称而不是id作为params，那么您需要更新complete动作以按名称查找订单。

但我的猜测是它是默认id 。 所以将订单对象传递给路径应该有效。
