query across tables
I am trying to do things the proper rails way and use the auto generated
id to refernce other tables. Now I''ve hit a wall in trying to write a
query.
timesheets:
id, employee_id, code_id, ... values
codes:

How to copy between databases?
I want to copy data from one database to another using rails. But, it seems
that rails only will talk to one database at a time. Is there a way around
this?
Any help would be greatly appreciated.

In a find, can''t you use both :include and :limit ?
I''m trying to do a find that includes a join. It has to be a find

Here''s the type of thing I want to do:

Polymorphic associations?
I''ve read the stuff about polymorphic associations here:
http://wiki.rubyonrails.org/rails/pages/UnderstandingPolymorphicAssociations
But I''m not sure what exactly they are and what their advantage is. Are
they the same as HABTM, but they''re "two-way"?

Changing default date format in Rails
I''ve spent all day digging through the rails api and postgres-pr on
this, I think it''s time to ask the list.
Postgres stores a Date in YYYY-MM-DD format. My users want the dates
in MM/DD/YYYY format.
Sure, I could explicitly convert it on the app level every place where
a date is displayed, but that seemed like a DRY violation.
