在 Rails 2.3.8 上设置设计/mongomapper答案

【问题标题】：Setting up devise / mongomapper on Rails 2.3.8在 Rails 2.3.8 上设置设计/mongomapper

【问题描述】：

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/ （除了将 routes.rb 更改推迟到生成器运行以解决错误之后）

我得到了它，只要让以下路径工作： /users/sign_up :: /用户/登录:: /用户/密码/新:: /用户/确认/新

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

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:

Missing host to link to! Please provide :host parameter or set default_url_options[:host]
Extracted source (around line #5):

3: <p>You can confirm your account through the link below:</p>
4: 
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....

【问题讨论】：

您解决过注册请求错误吗？我按照教程并将以下内容添加到 config/environments/production.rb: config.action_mailer.default_url_options = {:host => 'mydomain.com'} 但我得到了同样的错误。

【解决方案1】：

您遇到的至少一个问题是您没有为您在 config/routes.rb 文件中指定的根路由创建控制器。运行对 rails generate controller [name] 的调用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。
