Devise 3 (rails 4) can't update user without password

Question

I\'m trying to update a user without having to provide a password, but approaches that worked on older devise/rails versions no longer work with devise 3 and rails 4 strong para

Answer 1

I went round in circles on this for ages. The answers are all in validatable as suggested by mrstif above. If you use the validatable module Devise works out of the box (with configuration options) allowing you to update user details without supplying a password so be very careful about rolling your own password validations.
