Question

I know that objects in Rails that extend ActiveRecord::Base can use a constructor that takes a hash of attributes names to values, but I can’t seem to find where that hash constructor is actually defined (doesn’t seem to be directly in ActiveRecord::Base). Can anyone point me to where that constructor exists?

In rails 3.2.7 the initialize method appears to be in ActiveRecord::Base.

In the current master (commit c10202208982bfa02ffd16d1614992228391d781 at time of writing), Base includes ActiveRecord::Model, which in turn includes ActiveRecord::Core, where initialize is defined. It appears to be very similar to the method in 3.2.7.
