为什么此路由在heroku上不起作用，但在本地起作用？ [英] why doesn't this routing work on heroku but works locally?

问题描述

在我的route.rb文件中，有 Rails 3 ：

I have the following in my routes.rb file for Rails 3:

 13   namespace :user do
 14     root :to => "users#profile"
 15   end

我在heroku上收到此错误：

I get this error on heroku:

ActionController::RoutingError (uninitialized constant User::UsersController):

我已经重新启动了应用程序。

I already restarted the application.

我这样做是因为我正在使用devise，这就是它所说的Wiki：

I am doing this because I am using devise and this is what it says on the wiki:

https://github.com/plataformatec/devise/wiki/How-To:-Redirect-to-a-specific-page-on-successful-登录

推荐答案

问题是Rails期望模块中的控制器称为 Users ，因为这就是 namespace：user 的推断。也许您是想使用 scope 而不是 namespace ？

The problem is that Rails is expecting there to be a controller within a module called Users because that's what namespace :user infers. Perhaps you meant to use scope instead of namespace?

scope :path => "user" do
  root :to => "users#profile"
end

注意：在这种情况下，如果您只有一种方法，使用 scope 并不明智，但是如果您有多个带有 / user 前缀的那么就可以了如果您只有一个，我会改为：

Note: in this situation if you've only got one route it would not be wise to use scope, but if you've got multiple ones with the /user prefix then it would be fine to. If you only had one, I would do this instead:

get '/user', :to => "users#profile"
