Why string.classify is not working as expected?

Using rails 4, 'popup_cta'.classify results into PopupCtuminstead of PopupCta

I tried 'popup_cta_'.classify generates the expected result PopupCta

Also, when add a resource of popup_cta in the routes the rails will create popup_ctam helper

Any idea?

Solution

  • That's because classify works under the assumption that you're passing as parameter a table name, which are usually in plural and transform it to singular.
    I'm not an native english speaker, so I'm not quite sure what's that specific rule where words in plural that finish with a, in their singular form finish with um, but what you want to achieve, it can be done with camelize:

    'popup_cta'.camelize # => "PopupCta"

    About your issue with routes, you could override the helper name with :as.
