Question

我正在尝试使用devise和mongomapper进行基本身份验证。按照这里的说明： http://johnwyles.com/2010/03/15/sessions-in-mongodb-using-mongomapper-and-devise/ （除了推迟routes.rb更改，直到运行生成器以解决错误）

我得到了以下路径： / users / sign_up :: / users / sign_in :: / users / password / new :: /用户/确认/新

然而，只是尝试点击“/”会给我一个错误

NameError in UserController#sign_in

uninitialized constant UserController
RAILS_ROOT: /Users/bentrevino/Documents/Dev/devisetest

提交注册请求后，我收到此错误

RuntimeError in Registrations#create

Showing /Library/Ruby/Gems/1.8/gems/devise-1.0.8/app/views/devise_mailer/confirmation_instructions.html.erb where line #5 raised:

5: <p><%= link_to 'Confirm my account', confirmation_url(@resource, :confirmation_token => @resource.confirmation_token) %></p>

有人知道这里会发生什么吗？谢谢！本....

您遇到的至少一个问题是您没有为config / routes.rb文件中指定的根路由创建控制器。运行一次调用rails generate controller [name]来创建一个新的控制器。然后在config / routes.rb文件中为我们的根路由指定该名称。

在Rails 2.3.8上设置devise / mongomapper
