I just used before_save callback in user model like this.
class User < ActiveRecord::Base
before_save :limited_sign_up_inactive
private
def limited_sign_up_inactive
@allowed_emails = LimitedSignup.pluck(:email)
unless @allowed_emails.include? self.email
self.status = false #getting error in this line
end
end
end
Am getting this error
NoMethodError at /users
undefined method `users_url' for #<Devise::RegistrationsController:0xb4b8c18>
while using this line
self.status = false
I want to change status to false before save based on condition. Help me to solve this problem.
Thanks in advance.

Solution:
changed before_save to after_create
and used this line
self.update_attribute(:status, false)
You have User model and status - is User instance attribute
You can change
self.status = false
to
update_attribute(:status, false)
Then you can use this flag in your business logic..
(But obvious you have to have a field status in users table in db)
