iconv deprecation warning with ruby 1.9.3

Question

I\'m getting this warning when I run rspec:

/gems/activesupport-3.1.0/lib/active_support/dependencies.rb:240:in `block in require\': iconv will be deprecated in          


        

Answer 1

You can pin down the exact location of the warning by generating exceptions for ActiveSupport::Deprecation, instead of just printing to the log. At the top of application.rb:

ActiveSupport::Deprecation.behavior = Proc.new do |message, backtrace|
  raise message
end

Once you've figured out where the warning is coming from (by inspecting the full backtrace), remove this again.
