[英]Ruby routes and custom action
I'm trying to incorporate Devise and Cancan into a web app. 我正在尝试将Devise和Cancan整合到网络应用中。 I want users with :role => "admin" to be able to delete users, and Devise's destroy action only allows users to delete themselves, so I've created a custom action for this purpose.
我希望具有:role =>“ admin”的用户能够删除用户,并且Devise的destroy操作仅允许用户删除自己,因此我为此创建了一个自定义操作。 (To override the plugin's controller file, I've copied the registrations controller over to app/controllers/registrations_controller.rb.)
(要覆盖插件的控制器文件,我已将注册控制器复制到app / controllers / registrations_controller.rb。)
Here is my custom action in my registrations_controller.rb: 这是我的registrations_controller.rb中的自定义操作:
def destroy_user_account
@user = User.find_by_id(params[:user])
@user.destroy
redirect_to profiles_path, :flash => { :success => "User deleted!" }
authorize! :destroy, User, :message => "You don't have authorisation to delete this user."
end
Here is how I'm trying to use it, in a link on the page where you view a user's profile. 在您查看用户个人资料的页面上的链接中,这就是我尝试使用它的方式。 (I have things set up so that each user has_one profile; profiles are what you see at the front end. A profile is automatically created in the profiles table on user registration.)
(我已经进行了设置,以便每个用户都有has_one个人资料;个人资料就是您在前端看到的内容。个人资料会在用户注册时自动在个人资料表中创建。)
<% if can? :update, @profile %>
| <%= link_to 'Edit Profile', edit_profile_path(@profile) %>
| <%= link_to 'Edit Settings', edit_settings_path %>
<% end %>
<% if can? :destroy, @profile.user %>
| <%= link_to "Delete User", destroy_user_account(@profile.user),
:class => "delete",
:confirm => "Are you sure?",
:title => "Delete #{@profile.user.name}"
%>
<% end %>
My tests are showing 2 failures that I can't resolve: 我的测试显示2个无法解决的故障:

Also, when I try it out in my browser, clicking on the "Delete user" link gets me the following error: 另外,当我在浏览器中试用时,单击“删除用户”链接会显示以下错误:
Routing Error
路由错误
No route matches "/destroy-user-account/2"
没有路由匹配“ / destroy-user-account / 2”
Here are the routes that should cover this: 以下是应该涵盖的路线:
devise_for :users, #:path => '', :skip => [ :confirmations, :passwords, :registrations ], :controllers => { :registrations => "registrations" } do
devise_for:users,#:path =>'',:skip => [:confirmations,:passwords,:registrations],:controllers => {:registrations =>“ registrations”}做
# Routes for ACCOUNT REGISTRATIONS get "join", :to => "registrations#new", :as => :new_user_registration post "join", :to => "registrations#create", :as => :user_registration get "settings/account", :to => "registrations#show", :as => :settings get "settings/account/edit", :to => "registrations#edit", :as => :edit_settings put "settings/account", :to => "registrations#update", :as => :update_settings delete "close-my-account/:id", :to => "registrations#destroy", :as => :close_my_account delete "destroy-user-account/:id", :to => "registrations#destroy_user_account", :as => :destroy_user_account
Can anyone help with what I'm doing wrong? 谁能帮我解决我做错的事情?
In the browser it isn't matching the route because you're sending a GET
request but the route only matches a DELETE
request. 在浏览器中,它与路由不匹配,因为您正在发送
GET
请求,但路由仅与DELETE
请求匹配。 The test fails because the route gives the name destroy_user_account_path
instead of destroy_user_account
. 测试失败,因为路由的名称为
destroy_user_account_path
而不是destroy_user_account
。
Try: 尝试:
<%= link_to "Delete User", destroy_user_account_path(@profile.user),
:class => "delete",
:confirm => "Are you sure?",
:title => "Delete #{@profile.user.name}"
:method => :delete
%>
