In my app, there are a list of files that people need to upload. I had set things up so that they could pick the type of file from a dropdown list. The list of files are:

DOC_CLASSES = ["CV", "Research Statement", "List of Publications", "Cover Letter"]

In my form, I use collection_select to display these types in a dropdown list. The option I use is to :titleize them all. The problem is that this makes the option “CV” appear as “Cv”. The solution is to define a new acronym for CV.

In config/initializers/inflections.rb

ActiveSupport::Inflector.inflections(:en) do |inflect|
	inflect.acronym 'CV'
end

Now, CV appears as CV in the dropdown list.
