Continue reading »]]> I am proud to have published my first useful ruby gem.
It is called gettext_column_mapping, you can check out the code in my github repository.
I already released it as a gem through gemcutter/rubygems

It is based upon Masao Mutoh (gettext and gettext_active_record) and Michael Grosser (fast_gettext and gettext_i18n_rails) works.

Thanks to them

History

In my company we need a mean to translate bad written fields/table name in our database. Why ? because our applications are internationalized and we need to have cleaner name than “libelle” (the french word standing for label) to send to translators.

We also have some “constants” name saved in our tables so we need to translate them.

Then started this library a year ago.

Formerly, it was a library that depends on Rails … But I decided that it ccould be nice if it reaches these requirements :

• Use of Rubygem to spread it more easily
• Must be Rails agnostic
• Can use either mutoh’s gettext or grosser/fast_gettext
• Can be implemented easily on rails 2.3.x and 3.0 or other ruby web framework
• Can have some built-in configurable rake tasks

All is done!

But now I would like to improve this gems (API, tests, documentation, implementation) , so if someone who reads this post can help … I must remind you that this project is open source. Partly, it has been developped at work but I burnt most many hours of my sparetime than at work

TODO ?

• other database implementation (only mysql for now)
• ORM agnosticism ?
• More testing
• More documentation
• Rails < 2.3 compatibility backward
• … and so many

Try it and give me feedback

Well I did not test other gems of the mutoh gettext set of libraries but here is the gulty code that breaks rails.
Since Activerecord::Errors changed its implementation a bit, an error like this is raised :

NoMethodError: undefined method `gsub' for #<ActiveRecord::Error:0x00000002919738>
        from /home/hallelujah/Jail/lib/ruby/gems/1.9.1/gems/gettext_activerecord-2.0.4/lib/gettext_activerecord/validations.rb:165:in `localize_error_message'
        from /home/hallelujah/Jail/lib/ruby/gems/1.9.1/gems/gettext_activerecord-2.0.4/lib/gettext_activerecord/validations.rb:112:in `block (2 levels) in each_with_gettext_activerecord'
        from /home/hallelujah/Jail/lib/ruby/gems/1.9.1/gems/gettext_activerecord-2.0.4/lib/gettext_activerecord/validations.rb:112:in `each'
        from /home/hallelujah/Jail/lib/ruby/gems/1.9.1/gems/gettext_activerecord-2.0.4/lib/gettext_activerecord/validations.rb:112:in `block in each_with_gettext_activerecord'
        from /home/hallelujah/Jail/lib/ruby/gems/1.9.1/gems/gettext_activerecord-2.0.4/lib/gettext_activerecord/validations.rb:112:in `each_key'
        from /home/hallelujah/Jail/lib/ruby/gems/1.9.1/gems/gettext_activerecord-2.0.4/lib/gettext_activerecord/validations.rb:112:in `each_with_gettext_activerecord'

You can add this piece of code after your gems and rails are loaded (e.g at the bottom of config/environment.rb )

module ActiveRecord
  class Errors
    def localize_error_message_with_patch(attr,obj, append_field)
      obj = obj.respond_to?(:message) ? obj.message : obj
      localize_error_message_without_patch(attr,obj,append_field)
    end
    alias_method_chain :localize_error_message, :patch
  end
end

I think I will patch gettext_activerecord and the muto gettext set of library to fit in rails 2.3.4
Maybe I may keep an eye on Rails 3.0 development.
