Hi,
I wanted to check values before being saved, for example like this:
myobject.qty = 5
myobject.save
class ObjectClass
include DataMapper::Resource
before :save, :fix_qty
def fix_qty
if self.dirty.qty > self.qty
# do something
end
end
end
"self.dirty.qty" should have the new assigned value, and "self.qty"
the value from database
How should I do that?
