Ruby on rails 3 如果登录失败或用户不存在，则使用Desive rails 3重定向到注册页面

最近我安装了

gem'designe'，“1.5.2”

并尝试在用户不存在时将用户重定向到注册页/注册页。我尝试了多次更改路由，并使用if/else语句修改designe/sessions\u controller中的代码，如果用户身份验证失败，则重定向到注册页，但我想我遗漏了一些重要但简单的内容。我我在找一件像这样的东西

1。用户登录
1.1。如果user.authenticate！如果为true，则向他显示根路径（仪表板/索引） 其他的 重定向到注册/注册页面

我在Desive/sessions\u controller中做了许多更改，并创建了新的failure.rb，这样我可以重定向，但所有操作都失败了，我再次登录到同一页面，并显示了预期的flash消息。请帮我解决问题。

您描述的是Desive的默认行为。你根本不应该改变路线。。。谢谢@tyler，我更改了路由以设计用户，但在单击signin后，由于没有与[POST]“/sessions/user”匹配的路由，我得到了路由错误…有什么帮助吗？？？
