子目录中的 Rails 应用程序

问题描述：

尝试在子目录中设置 Rails 应用程序.我的服务器是切诺基.我有一个基本网址:www.nonsense.com，这是一个 wordpress 博客，我想在 www.nonsense.com/rails_app 中设置一个 rails 应用程序.

Trying to set up a Rails app in a subdirectory. My server is Cherokee. I have a base url of: www.nonsense.com, which is a wordpress blog, and I wish to set up a rails app in, www.nonsense.com/rails_app.

谷歌的快速扫描让我使用:ActionController::AbstractRequest.relative_url_root = "/rails_app"

A quick scan of google led me to using: ActionController::AbstractRequest.relative_url_root = "/rails_app"

然而，这似乎在最新的 Rails 中被删除了.关于 Rails 2.3.8 中的等价物的任何想法?

However, it seems this has been removed in the latest Rails. Any ideas as to the equivalent in Rails 2.3.8?

答

对于 Rails 4/5，您可以在 application.rb 或 production.rb 中设置:

For Rails 4/5, you can set this in application.rb or production.rb:

config.relative_url_root = "/app1"

或者简单地设置这个环境变量:

Or simply set this environment variable:

RAILS_RELATIVE_URL_ROOT='/app1'

但是，我发现这只是在资产路径前加上前缀.由 url 助手创建的 URL 路径不遵守此设置.

However, I've found that this only prefixes paths to assets. URL paths created by url helpers doesn't respect this setting.

事实证明，有一个与此相关的错误:https://github.com/rails/rails/issues/5122

Turns out, there's a bug related to this: https://github.com/rails/rails/issues/5122

这应该已经修复了它，但我没有发现情况是这样:https://github.com/rails/rails/pull/18775/files

This is supposed to have fixed it, but I've not found that to be the case: https://github.com/rails/rails/pull/18775/files

此功能的文档并不清楚它应该如何工作:

The documentation for this feature isn't very clear on how exactly it's supposed to work:

http://edgeguides.rubyonrails.org/configuring.html#deploy-to-a-subdirectory-relative-url-root

也许可以试试命名空间:
http://guides.rubyonrails.org/routing.html#controller-命名空间和路由

Maybe try namespacing instead:
http://guides.rubyonrails.org/routing.html#controller-namespaces-and-routing
