update_attributes and validations
I have a Person model. Person has_many lab_urls. The LabUrl model has a title and a url, which are both required. Now, I want to update a LabUrl object and stick some invalid data in there. And I want the person that has that invalid LabUrl to now be invalid, too. That doesn''t seem like too much to ask for. How can I do that? Right now, this is happening: >> me = Person.find(1)
