Question

我是Ruby的新手。对不起，我的英语。

我需要创建一个销毁所有用户对象的按钮（名为Relations和ListRelations的模型）。

这是我的config / routes.rb的一部分：

  devise_for :users, controllers: { omniauth_callbacks: 'omniauth_callbacks' }
  resources :relations
  resources :list_relations
  delete '/relations/destroy_member_data' => 'relations#destroy_member_data'

relations_controller.rb

  def destroy_member_data
    if current_user.relations.destroy_all && current_user.list_relations.destroy_all
      redirect_to(relations_path, :notice => 'All relations were successfully destroyed')
    else
      redirect_to(relations_path, :warning => 'Something went wrong. Please, try again.')
    end
  end

relations / index.html.slim：

= link_to 'Destroy all data', relations_destroy_member_data_path, method: :delete, data: {confirm: 'Are you sure?'}

当我单击此链接时，出现此错误：

Couldn't find Relation with 'id'=destroy_member_data

Extracted source (around line #59):

58: def destroy
59:    @relation = Relation.find(params[:id])

有人可以帮助我吗？预先谢谢你。

由于/relations/destroy_member_data与/relations/:id的删除路由匹配，因此destroy_member_data被视为ID，并且此路由是在之前定义的

两种解决方法

在resources :relations
这也应该工作而且更干净

resources :relations do
  delete :destroy_member_data, on: :collection
end

为什么我的应用程序使用destroy而不是自定义操作？
