Rails - Mar 2007 - how to have default param if loading page the first time

lo there,
i have a page with a date_select on it. When the date is passed, i
need it to pass back to the same action (reloading the page with a new
date). Now, i want the default date to be yesterday. This is for the
first time the page is hit, but i don''t know how to set my controller
up like that.

def pull_records_from_date
    @start = params[:start]
     do some stuff here
end

how do i let the controller know to pick yesterday for a start date
( ruby date object ) if nothing was passed to the action ?

thanks

Greatest little operator in Ruby: ||
def pull_records_from_date
   @start = params[:start]
###
   @start ||= Date.yesterday
###
    do some stuff here
end

Which basically says "if there''s nothing here yet, do another
assignment
check!"
