human_attribute_name defaults to the wrong locale

Question

I am developing a localised application with Rails 3.2.8, deployed on Heroku. I created a localisation it.yml file with the following structure:

it:
  activerecord:
    attributes:
      company:
        name:             "Nome"
        address:          "Indirizzo"
        phone:            "Telefono"

I then use:

Company.human_attribute_name(:name)

to get localised labels in my views. The default locale is :it.

When I switch to English everything works fine on my local environment, but once I deploy to Heroku something goes wrong with the localisation, and human_attribute_name seems to return Italian even when I switch the locale.

Am I doing something wrong with the above, or missing something?

Answer 1

Found the cause. In my production environment I had:

config.i18n.fallbacks = true

Switching it to false made the application behave correctly.
