I've done some searching and have found some nested hash references but
not quite enough to get me going with what I need.

I'm looking to build a structure like so...

actuals = {actual_id, {date => count, date => count, date => count}}

An example would be like:

actuals = {"1", {"01-01-2008" => 5, "01-02-2008" => 10}}

Then I can later iterate through the hash and for each ID, get any date
associated with it an associated count.

I'm pulling the data in with an ActiveRecord find that will return a
dozen or so records for a given id but with various dates and counts.

So records returned could look like

1, "01-02-2008", 5
1, "01-03-2008", 10
2, "12-25-2007", 5
1, "01-04-2008", 15

Should result in a hash when I'm finished like so:

actuals =
{"1",{"01-02-2008" => 5, "01-03-2008" => 10 "01-04-2008" => 15}},
{"2",{"12-25-2007" => 5}}

Iterating through those records is no problem...  I just can't wrap my
brain around the nested hash of dates and counts for a given id.

I'm assuming this is the appropriate and most effective data structure
for this data but I would be up for any other suggestions.

I appreciate any responses, thanks.
