user input validation and field dependencies

[Ilya Obshadko <il...@gmail.com>]

If form fields are dependent on each other, and I have to check other
fields' values to decide if current field input is valid or not, how could I
check other fields' values inside the Validator implementation?

I couldn't find a way to do that, so maybe writing a mixin would be better?

Thanks in advance.
