Rails - May 2006 - Storing BigDecimal in the db

I need to do some precise math, going to 12-14 decimal places, so I''m
using BigDecimal.  How can I store this in a db?  I''m using postgresql
8.1.0, if that matters at all.  I found a plugin [1] but it gives me
the error "You have a nil object when you didn''t expect it!  The
error
occurred while evaluating nil.each_pair," with no line number.  The
plugin itself never calls #each_pair, so it has to be somewhere inside
Rails or the postgres adapter.  I''m using Rails 1.1.2 and the postgres
0.7.1 adapter.

Hrm, referenced a link and forgot to include it.

Hi Pat

I wrote that :)

Can you be more specific about what you are trying to do?  Maybe I can help 
track down the issue.

Hey Ashley,

I''m using Duane Johnson''s column_comments plugin [1], and
that''s where
the error popped up.  I''m not entirely sure why the error occurs, as I
just wrapped the problem code in an "unless cols.nil?...end" block.
Anyway it''s nothing wrong with your plugin.  Now schema dumps actually
work :)  Thanks for doing this, and I''ll look into the column_comments
plugin and get a solution for Duane.
