Rails module names with acronym inflections

Question

Looks like inflections don't work for module names with the nesting level more than one.

If you have the following in your config/initializers/inflections.rb:

ActiveSupport::Inflector.inflections do |inflect|
  inflect.acronym 'VCloud'
end

Then when you create a directory under app/, say app/services/vcloud/ you will get two modules:

Vcloud #=> Vcloud
VCloud #=> VCloud

But if you create a directory with a higher nesting level, say app/services/vmware/vcloud/ you will get only one module:

Vmware::Vcloud #=> Vmware::Vcloud
Vmware::VCloud #=> NameError: uninitialized constant Vmware::VCloud

Is this a bug?

Answer 1

I would go with this is a bug. You can go around it with (within initializers):

module ActiveSupport::Inflector
  def underscore_with_acronym_fix(string)
    words = string.split('::')
    return words.map(&method(:underscore)).join('/') unless words.one?
    underscore_without_acronym_fix(string)
  end

  alias_method_chain :underscore, :acronym_fix
end

I'll make a pull request to fix this, however will need slightly more time to confirm it will not break anything. There are quite a lot of cases here.
