ActiveRecord RecordNotFound localization

Question

I am trying to localize my rails application (webservice). I installed the gem 'rails-i18n', which works fine.

Except that it does not translate ActiveRecord::RecordNotFound message. In rails code: https://github.com/rails/rails/blob/3-2-stable/activerecord/lib/active_record/relation/finder_methods.rb

raise RecordNotFound, "Couldn't find #{@klass.name} with #{conditions.to_a.collect {|p| p.join(' = ')}.join(', ')}"

It seems that the message is hard coded.

Is there any solution, apart not using the Model.find_by_'attribute' ?

Answer 1

Sufficient for my reason to tell user more informative message:

exception.message.match /^Couldn't find (\w+) with (id=([\S]*))?/
msg = t 'activerecord.exceptions.not_found', klass: $1, id: $3

and since I wanted a czech transaltion:

cs:
  activerecord:
    exceptions:
      not_found: "Nelze nalézt %{klass} s id=%{id}"

..when is something hard coded the only way is to hard de-code it
