First produce new field. for reference http://guides.rubyonrails.org/migrations.html

Do you have add your new fields in user controller parameter?

   def user_params
      params.require(:user).permit(:email, :password, :password_confirmation)
    end

    def sign_up_params
      params.require(:user).permit(:email, :password, :password_confirmation)
    end

In the application controller

before_filter :configure_permitted_parameters, if: :devise_controller?

  protected

  def configure_permitted_parameters
    devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:email, :password, :password_confirmation)}

    devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:email, :password, :password_confirmation)}
  end

In your registration form that override devise add this

class Users::RegistrationsController < Devise::RegistrationsController
     skip_before_filter :verify_authenticity_token, :only => [:ipn_notification]
  def sign_up_params
      params.require(:user).permit(:email, :password, :password_confirmation)
  end

After that add your new fields in all views _form,show,edit,index.
