I have a legacy Rails application which I want to upgrade to recent Rails and Ruby versions.To start with I am trying to setup the application with Ruby 2.1.2
$ rails -v
Rails 2.3.18
$ ruby -v
ruby 2.1.2p95 (2014-05-08 revision 45877) [i686-linux]
When I tried to run the rake task rake db:schema:load RAILS_ENV=test I encountered following error
can not load translations from /activesupport-2.3.18/lib/active_support/locale/en.yml, the file type yml is not known
Searching through Google I found the following reference https://github.com/rails/rails/issues/10514 which mentioned that there is incompatibility between Rails 2.3 and Ruby 2+ versions.
Can anybody please help me applying a monkey-patch mentioned about in the reference link?
Thanks, Jignesh
Finally resolved the error
can not load translations from /activesupport-2.3.18/lib/active_support/locale/en.yml, the file type yml is not known
by monkey-patching the Rails’s I18n::Backend::Base#load_file(filename) method.
The solution is as follows:
1.1 Created a file named ruby2.rb at /config/initializers
1.2 Added following contents to /config/initializers/ruby2.rb
if Rails::VERSION::MAJOR == 2 && RUBY_VERSION >= '2.0.0'
module I18n
module Backend
module Base
def load_file(filename)
type = File.extname(filename).tr('.', '').downcase
# As a fix added second argument as true to respond_to? method
raise UnknownFileType.new(type, filename) unless respond_to?(:"load_#{type}", true)
data = send(:"load_#{type}", filename) # TODO raise a meaningful exception if this does not yield a Hash
data.each { |locale, d| store_translations(locale, d) }
end
end
end
end
end
1.3 Finally ran
$ rake db:schema:load RAILS_ENV=test
and the schema was successfully loaded.
Most helpful references I could find and which helped me get to the solution:
