        logout_keeping_session!
        user = User.authenticate(params[:login], params[:password])
        if user
          # Protects against session fixation attacks, causes request forgery
          # protection if user resubmits an earlier form using back
          # button. Uncomment if you understand the tradeoffs.
          # reset_session
          self.current_user = user
          new_cookie_flag = (params[:remember_me] == "1")
          handle_remember_cookie! new_cookie_flag
          redirect_back_or_default('/')
          flash[:notice] = "Logged in successfully"

路线

  map.logout '/logout', :controller => 'sessions', :action => 'destroy'
  map.login '/login', :controller => 'sessions', :action => 'new'
  map.register '/register', :controller => 'users', :action => 'create'
  map.signup '/signup', :controller => 'users', :action => 'new'
  map.resources :users

  map.resource :session

您是否尝试过使用redirect_to 而不是渲染？

进一步检查后，这可能与您的map.resource 通话有关。当使用单数 map.resource（而不是复数）时，不会为 index 创建默认路由。

您可能需要rake:routes 以查看您的可用路线，并查看map.resource here 的信息。
