In Rails when using the Devise gem how to create a user without email and password?

devise, ruby-on-rails, ruby-on-rails-4

Solution

you can override them in your user model:

def password_required?
  false
end

def email_required?
  true
end

Edit:

def password_required?
   new_record? ? false : super
end

Problem

In my Rails app, Admins are the people who add users to the system. If the user doesn't have an email, a password won't be generated for him and he can't log in. But if the user have an email, a password will be generated. But the problem is, devise won't allow blank passwords. How can we fix this?
