Ruby路由和自定義操作

Question

我正在嘗試將Devise和Cancan整合到網絡應用中。 我希望具有：role =>“ admin”的用戶能夠刪除用戶，並且Devise的destroy操作僅允許用戶刪除自己，因此我為此創建了一個自定義操作。 （要覆蓋插件的控制器文件，我已將注冊控制器復制到app / controllers / registrations_controller.rb。）

這是我的registrations_controller.rb中的自定義操作：

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

在您查看用戶個人資料的頁面上的鏈接中，這就是我嘗試使用它的方式。 （我已經進行了設置，以便每個用戶都有has_one個人資料；個人資料就是您在前端看到的內容。個人資料會在用戶注冊時自動在個人資料表中創建。）

    <% 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 %>   

我的測試顯示2個無法解決的故障：

1）以管理員身份登錄時，ProfilesController GET show應該具有編輯配置文件的鏈接失敗/錯誤：get：show，：id => @profile ActionView :: Template :: Error：undefined method destroy_user_account' for #<#<Class:0x105b474a8>:0x1057f32e8> # ./app/views/profiles/show.html.erb:41:in views destroy_user_account' for #<#<Class:0x105b474a8>:0x1057f32e8> # ./app/views/profiles/show.html.erb:41:in ___917863454_2195331000_0'＃./spec/ destroy_user_account' for #<#<Class:0x105b474a8>:0x1057f32e8> # ./app/views/profiles/show.html.erb:41:in profiles_controller_spec.rb:143

2）以管理員身份登錄時，ProfilesController GET顯示應具有刪除用戶帳戶的鏈接（使用注冊控制器中的destroy_user_account操作）失敗/錯誤：get：show，：id => @profile ActionView :: Template ::錯誤： destroy_user_account' for #<#<Class:0x105b474a8>:0x105806d20> # ./app/views/profiles/show.html.erb:41:in views destroy_user_account' for #<#<Class:0x105b474a8>:0x105806d20> # ./app/views/profiles/show.html.erb:41:in ___917863454_2195331000_0'＃。/ spec / destroy_user_account' for #<#<Class:0x105b474a8>:0x105806d20> # ./app/views/profiles/show.html.erb:41:in profiles_controller_中的未定義方法destroy_user_account' for #<#<Class:0x105b474a8>:0x105806d20> # ./app/views/profiles/show.html.erb:41:in

另外，當我在瀏覽器中試用時，單擊“刪除用戶”鏈接會顯示以下錯誤：

路由錯誤

沒有路由匹配“ / destroy-user-account / 2”

以下是應該涵蓋的路線：

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 

誰能幫我解決我做錯的事情？

在瀏覽器中，它與路由不匹配，因為您正在發送GET請求，但路由僅與DELETE請求匹配。 測試失敗，因為路由的名稱為destroy_user_account_path而不是destroy_user_account 。

嘗試：

<%= link_to "Delete User", destroy_user_account_path(@profile.user), 
                        :class => "delete", 
                        :confirm => "Are you sure?",
                        :title => "Delete #{@profile.user.name}"
                        :method => :delete
%>
