Routing errors when upgrading from rails 3.1 to rails 3.2 due to underscores in module namespaces

Question

We have a rails application and we have a API namespace defined as Api::V1, Api::V1_2, Api::V1_3 etc.

In routes.rb, we have set the following

namespace :

Came across same thing once. There was this bug on their github issue list

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

Then a pull request

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

But the discussion did not come to any solution. The common statement was like

Don't like undescores in Modules.

So you'll have to remove your underscores from the Module names
