十万个为什么

为“十万个为什么”而努力！

问题描述

现有路由器规则如下：

get 'my', to: 'users#profile'
get 'my/books', to: 'users#books'

devise_for :users, :controllers => {:omniauth_callbacks => 'users/omniauth_callbacks'} 
resources :users, only: [:show, :edit, :update] do
  member do
    get :avatar
  end
  resources :books
end

执行rake routes后，输出如下：

                      my GET      /my(.:format)                                 users#profile

                         DELETE   /users(.:format)                              devise/registrations#destroy

                         PUT      /users/:user_id/books/:id(.:format)          books#update
                         DELETE   /users/:user_id/books/:id(.:format)          books#destroy
               edit_user GET      /users/:id/edit(.:format)                     users#edit
                    user GET      /users/:id(.:format)                          users#show
                         PUT      /users/:id(.:format)                          users#update

问题

1. 访问/users/password/edit（修改密码）页面，直接重定向到/users/:user_id/edit页面。并且，提示“您已经登录”。 为什么会成重定向？如何才能不重定向？
2. 对于用户注册、修改用户信息、修改密码等 URL，有没有一种比较好的命名规则？

环境

1. Rails 3.2.14
2. Devise 3.0.3
