Question

我们有一个rails应用程序，我们有一个API命名空间，定义为Api :: V1，Api :: V1_2，Api :: V1_3等。

在routes.rb中，我们设置了以下内容

namespace :api do
  ["v1", "v1.2", "v1.3", "latest"].each do |name|
    namespace name, {:module => name.gsub(".","__"), :as => name.gsub(".","_") } do
      constraints :format => /json/ do

      # user scoped views

      resources :some_endpoint, :only => [:create, :index, :show, :update, :delete], :path => "scheduler" do
        member do
          put 'edit'
          post 'duplicate'
        end
      end
    end
  end
end

使用Rails 3.1运行时工作正常，但我们在rails 3.2中遇到路由错误：

当我们使用rails 3.1运行它时，上面转换为Api :: V1_2。

知道这里的错误是什么，我该如何解决？该代码在所有其他情况下都能正常工作，包括渲染资产等。只有在这种情况下，rails才会抛出错误。

遇到过同样的事情。他们的github问题清单上有这个错误

https://github.com/rails/rails/issues/5849

然后是拉取请求

https://github.com/rails/rails/pull/6105

但讨论没有得到任何解决方案。常见的陈述就像是

不喜欢模块中的不受欢迎。

因此，您必须从模块名称

中删除下划线

由于模块命名空间中的下划线，从rails 3.1升级到rails 3.2时出现路由错误
