Question

I’d like to translate the OpenIdAuthentication plugin into another language but I’d like not to change the plugin directly.

Here’s the basic structure of the messages I want to translate:

module OpenIdAuthentication    class Result     ERROR_MESSAGES = {       :missing      => 'Sorry, the OpenID server couldn't be found',       :invalid      => 'Sorry, but this does not appear to be a valid OpenID',       :canceled     => 'OpenID verification was canceled',       :failed       => 'OpenID verification failed',       :setup_needed => 'OpenID verification needs setup'     }    end  end

It is something possible to translate them without changing the plugin directly?

Thanks!

You can simply overwrite OpenIdAuthentication::Result::ERROR_MESSAGES by redefining it at any time after the plugin loads.

You may do so through a different plugin (that loads after OpenIdAuthentication), or from a file required after the plugin loads (e.g. require lib/open_id_authentication_suppl.rb in environment.rb):

The code will essentially be a copy-paste job, as follows:

module OpenIdAuthentication    class Result     ERROR_MESSAGES = {       :missing      => '<message in foreign language>',       :invalid      => '<message in foreign language>',       :canceled     => '<message in foreign language>',       :failed       => '<message in foreign language>',       :setup_needed => '<message in foreign language>'     }    end 

To integrate this with I18N-rails (built into Rails 2.2.2, available as a gem/plugin in previous versions), do:

  class I18NResultMessages     def [](key)       I18n.t(key, :scope => 'openidauthentication.errors.messages')     end   end    class Result     ERROR_MESSAGES = I18NResultMessages.new   end 

Then define and load your I18n yml file for openidauthentication.errors.messages‘s various locales on Rails startup, and don’t forget to set your I18n.locale every time you start processing a controller action based on the logged-in user’s locale.
