Inconsistency between date_select and datetime_select (patch proposal)

rubyonrails-core

[sorry for posting this twice, but i can’t see the first post on the list…] Help needed:

I’m working on a patch to datetime_select that covers two inconsistencies compared to date_select:

  • should support :order
  • should support :discard_year

I have basically copied and worked with code from date_select and copied the relevant down to datetime_select. But in my opinion, it’s not as beautiful as it could be. So, I’m posting here to get more eyes on it before submitting as a patch.

Any feedback appreciated.

Background on why we should eliminate these inconsitencies in rails core: http://groups.google.com/group/rubyonrails-core/browse_frm/thread/346cda3cd39e6fa9
