Question

sessions_controller.rb

  def create
    if user = User.authenticate(params[:login], params[:password])
      session[:user_id] = user.id
      redirect_to posts_path
    else
      render :action => 'new'
    end
  end


routes.rb

  get "sessions/create"
  get "sessions/destroy"
  get "sessions/new"

  resources :posts
  resource  :session
  resources :users

  match '/login',  :to => 'sessions#new',     :as => 'login'
  match '/logout', :to => 'sessions#destroy', :as => 'logout'

是否可以在render之后保留/ login url：action =＆gt; “新”??? 感谢。

Answer 1

redirect_to '/login'不保留render 'new'之类的帖子信息。

我对这个解决方案并不完全满意，但这就是我所做的：

resource :session, :only => [:create, :new, :destroy], 
         :path_names => { :new => 'login' }

它为您提供以下路线：

session POST /session（。：format）{：action =＆gt;“create”，：controller =＆gt;“sessions”}
new_session GET /session/login(.:format）{：action =＆gt;“new”，：controller =＆gt;“sessions”}
DELETE /session(.:format) {：action =＆gt;“destroy”，：controller =＆gt;“sessions”}

Answer 2

简单的解决方案是将render :action => 'new'更改为redirect_to '/login'。我并不是非常喜欢这个，但它应该为你解决问题。

登录尝试失败时/ session而不是/ login
