You can define initialize method in the Financing model something
along the lines
# lets set the default params for a new awardation
def initialize(params = {})
params[:start_of_period] ||=
Financing.find.previous.end_of_period
super(params)
end
It basically pre-initializes a record with some values.
Hope it makes sense.
