Question

I am trying to generate a quick registration form to use Facebook, Twitter and Linked sign in on my app. But I do have user model that validates some fields on the previous sign up procedure.

I am trying to extend the Registration controller, based on Devise, in order to use the same database for quick registration from the external sign in. This question is formulated because I am running a trial and then I have the sign up form asking for the credit card.

I have this controller:

class Users::QuickRegistrationController < Users::RegistrationsController

  self.model_class = Users::RegistrationsController

end

And then I have this user model:

class User < ActiveRecord::Base  
  validates :name, :presence => true
  validates :first_surname, :presence => true
  validates :prefered_language, :presence => true
  validates :dni, :presence => true, :uniqueness => true #, :format => {:with => /(^\d{7,8}[a-zA-Z]$)|(^[a-zA-Z]\d{7}[a-zA-Z]$)/, :unless => "dni.blank?"}
  validates :phone_number, :presence => true, :format => { :with => /^((\d{9})|([+]\d{11}))$/, :unless => "phone_number.blank?"}, :uniqueness => true
  validates :birthdate, :presence => true, :age => {:adult => :over}
  validates :legal_conditions, :acceptance => {:accept => true}
  validates :email, :confirmation => true
  validates :email_confirmation, :presence => true
  validates :password_confirmation, :presence => true, :if => "new_record?"
  validates :country, :presence => true

Can I say something like validates :first_surname, :presence => false for the Users::QuickRegistrationController and :first_surname, :presence => true for Users::RegistrationsController?

Additionally, there’s a solution to solve this issue on Ruby, can you provide any tutorial or related link?

As 23tux says, validations are based on the model. What I’d do is add a new column to your model:

add_column :products, :quick_registration, :boolean, default => true

Then in your User model:

class User < ActiveRecord::Base  
  validates :name, :presence => true
  validates :email, :confirmation => true
  validates :email_confirmation, :presence => true


  with_options :unless => :quick_registration? do |u|

    # These only validate during full registration
    u.validates :first_surname, :presence => true
    u.validates :prefered_language, :presence => true
    u.validates :dni, :presence => true, :uniqueness => true #, :format => {:with => /(^\d{7,8}[a-zA-Z]$)|(^[a-zA-Z]\d{7}[a-zA-Z]$)/, :unless => "dni.blank?"}
    u.validates :phone_number, :presence => true, :format => { :with => /^((\d{9})|([+]\d{11}))$/, :unless => "phone_number.blank?"}, :uniqueness => true
    u.validates :birthdate, :presence => true, :age => {:adult => :over}
    u.validates :legal_conditions, :acceptance => {:accept => true}
    u.validates :password_confirmation, :presence => true, :if => "new_record?"
    u.validates :country, :presence => true

  end
end

Then in your controller, you can ‘switch on’ the additional validations by setting quick_registration to false:

@user.quick_registration = false
@user.save   # all validations should fire
