heroku not loading language file

Question

Heroku does not seem to be loading config/locales/pt.yml. (Language is being set correctly to pt.)

I18n is working perfectly on localhost,

Answer 1

I ran into a similar issue, but mine was due to having duplicate keys.

In one file, we defined this:

en:
  dashboard: "Dashboard"

And another we defined

en:
  dashboard:
    title: "Some Title"

Locally, I18n.t("dashboard.title") worked just fine, but on production it did not. The reason was probably due to a load order difference between Heroku and my development machine.

I fixed it by changing the name of the first dashboard key so there was no longer an overlap.

Answer 2

Curiously, data were appearing in I18n.backend as expected but were not individually selectable using I18n.t

This led to the realization that the load path must be configured correctly for Rails to find the translation files, but that it was not parsing them properly.

This led to @ANeves discovering that a BOM was disrupting Heroku's ability to parse the files which resulted in the fix of removing the offending BOM.

Wikipedia on BOM in UTF-8

The Unicode Standard does permit the BOM in UTF-8, but does not require or recommend its use. Byte order has no meaning in UTF-8 so in UTF-8 the BOM serves only to identify a text stream or file as UTF-8.

Many Windows programs (including Windows Notepad) add BOMs to UTF-8 files by default.

If future readers are on ruby-1.9 consider reading about common encoding problems.

Answer 3

Writing this line will also fix the problem in your application.rb

config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s]

Answer 4

This issue does not appear to be Heroku-specific and would happen on any Windows/UNIX co-mingling with Ruby / i18n.

Answer 5

@Alexander Wenzowski sent me on the right track.

It seems the byte order mark was messing up Heroku's loading of localization files...
When I converted the files to not have BOM, using Notepad++, everything got fixed.

At first I was just trying to inspect this new thing for me, I18n.backend... and then I noticed what I had missed at first sight: that even though the data was there, it was all mangled.
