Question

我有一个使用devise + cancan的应用http://agile2go.herokuapp.com/。

在本地运行应用程序工作正常，但在Heroku上部署时，sign_up页面会显示错误消息。但是，sign_in页面工作正常！

我知道问题是在simple_form_for中调用资源时，当我拿出资源时它工作了：

<%= simple_form_for(resource, :as => resource_name, :url => registration_path(resource_name), :html => {:class => 'form-horizontal' }) do |f| %>

适用于sign_in页面！

这是我的routes.rb

authenticated :user do 
  root :to => "home#index"
end
root :to => "home#index"     
devise_for :users, :path => "auth"

点击链接时在导航栏上：

<li><%= link_to 'Login', new_user_session_path %></li>//works
<li><%= link_to 'Sign up', new_user_registration_path %></li>//does not work

最后Heroku记录：

我不知道为什么对name

说未定义的方法#<User:0x00000004317050>

我刚遇到同样的问题 - raking为我解决了这个问题。在你的控制台中试试这个：

$ heroku run rake db:migrate

设计本地工作但不在heroku上工作
