Ruby on Rails设计问题

Question

我试图解决这个问题的时间太长了，我希望在这里有所帮助。 我是Ruby的新手，并下载了devise gem，但是当我尝试运行注册页面时，在终端中出现此错误：

Started GET "/users/sign_up" for 127.0.0.1 at 2013-09-11 17:52:28 -0700

我想这意味着我没有前往注册页面的路线。 我该如何设置。 我在网上查看并尝试了几乎所有内容，似乎没有任何效果。

Answer 1

首先，请确保按照此处的说明正确设置Devise ... https://github.com/plataformatec/devise

具体来说（在获得Devise宝石之后）...

rails generate devise:install

其次是...

rails generate devise MODEL

其中，MODEL通常是用户。

之后，假设您的链接正确无误，您的路线应该可以正常工作。 注册链接别名为...

new_user_registration_path 

如果正确设置，则route.rb中应包含以下内容...

devise_for :users

Answer 2

在你的routes.rb

devise_for :users

也许尝试跑步

rails g devise User

希望你已经跑了

rails g devise:install
