Validate Before Delete
I have an Order model with a ''status'' column. What I want to be able to do
is validate that the status of the Order is not completed before it is
allowed to be deleted. I tried the following method in my Model, but it
appears that this only works for an :update or :create on the record.
Anyone know how to do this, and if it should be in the model or the
controller?

Possible to check if form field is required?
Hi list,
is it possible to check if form field will be required when form is

method)? I could do this manually but it doesn''t seems to me very DRY.
For example, I would like to be able to dynamically add asterisk with
some helper method if city is required here:

DRY principle form validations
We are wondering how you''d validate a credit card number or a SSN

Would it be through Rails'' AJAX support?
