Rails 3 translations within models in production

Question

I\'m trying to translate an app into Japanese and everything was going smoothly until I put it into production.

As cache_classes is now true any translation within a mod

Answer 1

Don't think you're improving performance by caching the names in the class. Make it a method instead.

class TimeseriesForecast < ActiveRecord::Base
  def self.field_names
    { :location_name => I18n.t('forecast_timeseries.location_name'),
      :local_date_time => I18n.t('forecast_timeseries.local_date_time'),
      :zulu_date_time => I18n.t('forecast_timeseries.zulu_date_time'),
      :temp_mean => I18n.t('forecast_timeseries.temp_mean') }
  end
end

# usage
TimeseriesForecast.field_names

Better yet, return just the actual fields and do the translation in the view, if you're gonna be strict MVC about it (some Rails methods - like collection_select - make it harder to do that though, hence the suggestion above).
