设计签名链接问题(Rails4)

Question

我的导轨版本:

rails -v
Rails 4.0.2

我使用Devise作为用户模型.

注销链接是:

  <%= link_to 'Sign out', destroy_user_session_path, method: :delete %>

当我点击链接时出现此错误:

AbstractController::ActionNotFound at /users/sign_out
The action 'show' could not be found for UsersController

通过执行rake路由,我得到了这个:

destroy_user_session DELETE /users/sign_out(.:format) devise/sessions#destroy

登录development.log

Started GET "/users/sign_out" for 127.0.0.1 at 2013-12-28 20:45:06 +0000

AbstractController::ActionNotFound - The action 'show' could not be found for UsersController:

  actionpack (4.0.2) lib/action_dispatch/journey/router.rb:59:in `call'
  actionpack (4.0.2) lib/action_dispatch/routing/route_set.rb:680:in `call'

我不明白为什么它会搜索show动作.只是为了它的乐趣,我在用户控制器和节目视图中创建了show动作.它的作用是重定向到show动作.不知道为什么.

如果您需要任何其他信息,请告诉我.有什么线索有什么不对？

Answer 1

如果您正在为用户使用设计模型,并且您正在使用用户资源,那么请确保在/config/routes.rb中的"resources:users"之前提到"devise_for:users"
