Rails devise: user_signed_in? not working
提问by John
I have this in my view:
我认为：
<% if user_signed_in? %>
<%= current_user.email %>
<% else %>
<%= link_to "Sign in", new_user_session_path %><br />
<%= link_to "Opret", new_user_session_path %><br />
<% end %>
But when have signed in as a user: I still get the links in view:
但是当以用户身份登录时：我仍然可以看到链接：
<%= link_to "Sign in", new_user_session_path %><br />
<%= link_to "Opret", new_user_session_path %><br />
Why is the helper not working?

Did you use devise's before filter in your controller?
您是否在控制器中使用了设计之前的过滤器？
before_filter :authenticate_user!

Not sure what is behind the user_signed_in? method, either your login is not working correctly or your method is broken.
不确定 user_signed_in 背后是什么？方法，要么您的登录无法正常工作，要么您的方法已损坏。
Maybe try this, if that doesn't work, I would take a look at whats going wrong with the actual login.
也许试试这个，如果那不起作用，我会看看实际登录出了什么问题。
<%unless current_user.blank? -%>
signed in
<%else -%>
not signed in
<%end-%>

Make sure that you are using the right model. For example if your model is member then you should use member_sign_ininstead of user_sign_in.
确保您使用的是正确的模型。例如，如果您的模型是成员，那么您应该使用member_sign_in而不是user_sign_in.

If login is working properly, it could be because of some kind of caching going on?
如果登录工作正常，可能是因为正在进行某种缓存？

I had encountered exactly the same issue and solved it by doing
$bundle exec rails g devise useragain. My problem was devise_for userswas somehow missing in the routing file.
我遇到了完全相同的问题，并通过$bundle exec rails g devise user再次执行解决了它
。我的问题是devise_for users路由文件中不知何故丢失了。
