Question

我的问题是rails帮助器为我的用户模型User

生成错误的链接

<%= link_to "delete", user_registration_path(user), :method => :delete, :confirm => "You sure?" %>

生成以下网址： whatever.com/users.1

我的routes.rb：

put "rooms/:id/close" => "rooms#close", :as => "close_room"

devise_for :users, path_names: {sign_in: "login", sign_out: "logout"},
controllers: {omniauth_callbacks: "omniauth_callbacks"}
get "home/index"

resource :user do
  # Route GET /user/tandem
  get 'tandem', :on => :collection
  get 'practice', :on => :collection

end

root :to => 'home#index'

resources :rooms
match '/party/:id', :to => "rooms#party", :as => :party, :via => :get
match '/users/find', :to => "users#find", :as => :find_users, :via => :get
# Sample resource route (maps HTTP verbs to controller actions automatically):
match '/users/edit/:id', :to => "users#edit", :as => :edit_user, :via => :get
resources :users, only: [:index ,:show, :edit, :update]

我正在使用ruby'1.9.3'，'rails'，'3.2.13'，设计（2.2.4）。编辑操作也会发生这种情况。编辑：我的路线文件是

Answer 1

你应该改变

<%= link_to "delete", user_registration_path(user), :method => :delete, :confirm => "You sure?" %>

到

<%= link_to "delete", user_path(user), :method => :delete, :confirm => "You sure?" %>

user_registration_path与删除用户无关 - 实际上恰恰相反。

修改

看到你的rake routes输出后，似乎还有一些其他问题 - 有多个路径可以摧毁用户 - 你应该努力纠正这个问题，但以下一定会有效：

<%= link_to "delete", {controller: 'users', action: 'destroy', id: @user.id },
                      {method: :delete} %>

Answer 2

移除resource :user并将tandem和practice路由移至resources :users

如果你想保留/user/tandem类似的路线，

resource :user, only => [] do
  #tandem and practice routes as existing
end`

您应该添加：删除用户资源路由声明。

resources :users, only: [:index ,:show, :edit, :update, :delete]

并将link_to更改为users_path，如

link_to 'Destroy', users_path(user), method: :delete, data: { confirm: 'Are you sure?' }
