Rails - Jul 2006 - date_select and ActiveRecord find()

If I pass a date through date_select to a controller, can a Active
Record object be found based on this date that is passed?  Here is
what my log says:

ArgumentError (Unknown key(s): publication_date(2i),
publication_date(3i), publication_date(1i)):

Does this mean that I will have to drop down to select_date?  Do only
the methods new, create, and update_attributes work with date_select
on a AR object?

Thanks for all the help,

After much frustration, I found the solution to my own problem.  The way 
to do it seems to be to use date_select, then parse the params in a 
method in application.rb:

class ApplicationController < ActionController::Base
  def convert_date_from_params
    Date.new(params[:date][:year].to_i, params[:date][:month].to_i, 
params[:date][:day].to_i)
  end
end

If anyone else has a better solution, I''d love to hear it.

Best,

Scott Taylor
