Converting a Rails application from Gettext to I18n
Posted by admin
‘jaap’ wrote a rake task to convert your Rails application from using Gettext translation into the new I18n support, which is really great!
WARNING: Before you run the new rake task rake gettext_to_i18n:transform, read “So How Do You Fix It?” below
OK, so you’ve followed along in the article and now you want to test out your new localization system. Problem is when you try to start the server up script/server you get this error message:
/Users/cblackburn/Source/ruby/bols/lib/active_support/memoizable.rb:71:in `path': can't modify frozen object (TypeError)…or something similar.
What happened? Since you have frozen Rails and the rake task does not exclude the frozen vendor/rails directory, it modified memoizable.rb in ActiveSupport causing this error.
So How Do You Fix It?
Do one of the following:
- Backup lib/active_support/memoizable.rb before you run the rake task, then restore it after.
- Restore lib/active_support/memoizable.rb using your SCM.
For this project in my case it was
svn revert lib/active_support/memoizable.rb
