Today in #rubyonrails, kiwinewt asked:
How can I have a model with a text field and have that text field in multiple languages?
To which he meant that he has a model and he wants different versions of text displayed based on whatever the locale is set to. This is quite the common question in the channel and previously I’ve drawn blanks, but today I had a Moment of Clarity +10 and coded up something amazingly simple.
It has two parts. The first is the code in the model:
class Page < ActiveRecord::Base
def self.with_locale(&block)
page = scoped_by_locale(I18n.locale.to_s) { block.call }.first
page ||= scoped_by_locale(I18n.default_locale.to_s) { block.call }.first
raise ActiveRecord::RecordNotFound, "The page you were looking for does not have a version in #{I18n.locale}" if page.nil?
page
end
end
And the second is how you use it:
@page = Page.with_locale { Page.first }
Now if you set I18n.locale in your application and use with_locale it will automatically find records based on that locale.
