How to use Active Support core extensions

Question

I have Active Support 3.0.3 installed and Rails 3.0.3 with Ruby 1.8.7.

When I try to use 1.week.ago I get

NoMethodError: undefined meth         


        

Answer 1

You can granularly add libraries via the already mentioned

require 'active_support/core_ext/some_class/some_file'

There is also another level up where you can

require 'active_support/core_ext/some_class'

But, at the moment, this is unfortunately not available for Time, Date and DateTime.

A way around this is to require 'active_support/time' which will give you Time, Date and DateTime which would solve the OP was asking for without requiring everything.

My Rails patch, which adds active_support/core_ext/date and date_time, made it into Rails v4.0.0, so now you can require these individually. YAY!
