What''s the best idion when you need to present the user a single form, whose data is loaded into several models? Issues: * How to display the errors together * How do you handle one model being valid but not the other * How do you do validations if one model''s validity depends on the other (I guess transactions could be used to handle #2 and #3...) -- Posted via http://www.ruby-forum.com/.
Transactions can be used, but you can also validate by hand.
For #1 I would write a helper just like error_messages_for(), but then
something that accepts an array of models and creates error messages
like:
The #{attribute} of #{themodel} should be at least 4 characters.
