身份验证 – Rails设计不删除帐户

我让Devise使用注册,登录,编辑和查看用户配置文件.我唯一的问题是点击“删除帐户”只是重定向到/用户,并没有实际删除用户.我究竟做错了什么？

删除帐户按钮

= link_to "Cancel my account",registration_path(resource_name),:confirm => "Are you sure?",:method => :delete

据我所知,我没有改变任何会破坏这一点的东西.我想要使??用的删除帐户按钮是

= negative_trash_button_link_to "Cancel my account",:method => :delete,:confirm => "You sure?"

negative_trash_button_link_to位于css3buttons gem中.

编辑：我的routes.rb

resources :posts

ActiveAdmin.routes(self)

devise_for :admin_users,ActiveAdmin::Devise.config

root :to => "home#index"

devise_for :users do
  get "/users/sign_out" => "devise/sessions#destroy",:as => :destroy_user_session
end
resources :users,:only => :show
