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]

way cool, thanks very much sk

def pull_records_from_date   @start = params[:start] || (Date.today - 1).to_s   ... end
