Forum: Ruby on Rails Help with rails validates

I have a question on rails validates. I need to validate that one field 
is
filled out if another field has a certain value. The code is below, but 
if
license has extended selected then the extended license type needs to be
filled in. I have this but it isn't working, when I fill the form out 
and
select extended and don't check anything for extended_license_type, it
validates fine and I get no error message.

  validates :license, presence: true
  validates :extended_license_type, presence: true, :if =>
:license_extended?

private
    def license_extended?
      license == 'extended'
    end

Seems to look okay, but maybe try removing "private"
from the license_extended? method?

Meant to add: this could be the problem since the Validator object 
cannot
access the method on your model instance, so it's always returning 
"false".

I actually figured this out. Looged at the debug console on my app and
noticed that with the extended_license_type it was passing a '0' back 
since
none of the check boxes were checked. My validates only checks for the
presence of that field and '0' is something so that is what it was.
