我正在尝试使用 devise 和 mongomapper 进行基本身份验证。按照此处的说明进行操作：http: //johnwyles.com/2010/03/15/sessions-in-mongodb-using-mongomapper-and-devise/ （除非将 routes.rb 更改推迟到生成器运行以解决错误之后)
我得到了以下工作路径：/users/sign_up :: /users/sign_in :: /users/password/new :: /users/confirmation/new
但是，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

有人知道这里可能会发生什么吗？谢谢！本……
