我使用Omniauth作为我登录Rails应用程序的唯一方法.

问题是:当用户单击"注销"时,页面重新加载并且Logout链接仍然存在(尽管user_signed_in？逻辑包装它).这让我相信用户实际上并没有退出

这是我的index.html.erb:

<% if user_signed_in? %>
  <%= link_to "Authenticate with Google", user_omniauth_authorize_path(:google_oauth2) %>
<% else %>
  <%= link_to('Logout', destroy_user_session_path, :method => :delete) %>
<% end %>

还有我的user.rb

def self.from_omniauth(auth)
  if user = User.find_by_email(auth.info.email)
    user.provider = auth.provider
    user.uid = auth.uid
    user
  else
    where(provider: auth.provider, uid: auth.uid).first_or_create do |user|
      user.provider = auth.provider
      user.uid = auth.uid
      user.email = auth.info.email # THIS (user.email) value i want to provide to my registration form as default value
   end
  end
end

我的omn​​iauth_callbacks_controller.rb …

我正在尝试检查参数是否等于视图中的 if 语句的值：

<% if param[:knowsifemployermatches] == "Yes" %>show<% end %>

但我收到这个错误：

undefined local variable or method `param' for #<#<Class:0x000001070d2688>:0x00000103a8cf88>
