Devise super do with current record in user controller for sending mails in Ruby on Rails - devise

Question

I'm trying to set up a registration confirmation through email for the users. I'm using devise for authentication. But I could'nt access the saved user resource from the devise controller, though I tried a few tinkers in futile. If some Could lend a helping head, that's great!!!
I'm trying to send a confirmation link to the registered user after the user got saved. But I could not grab the new user records as any usual instance variable in the devise controller.
Now my user registrations controller looks like this:
class Users::RegistrationsController < Devise::RegistrationsController
before_action :select_plan, only: :new
# Extend the default Devise gem behaviour so that
# the users signing up with a Pro account(plan_id 2) should be
# saved with a Stripe subscription function
# Otherwise, save the sign up as usual.
def create
super do |resource|
# #user = User.new(configure_permitted_parameters)
if params[:plan]
resource.plan_id = params[:plan]
if resource.plan_id == 2
resource.save_with_subscription
else
resource.save
end
//These do not works and returns null
//#user = User.find_by_email(params[:email])
//#user = User.find(params[:id]
//#user = resource
UserMailer.registration_confirmation(params[:email]).deliver
flash[:success] = "Please confirm your email address to continue"
redirect_to root_url
end
end
end
private
def select_plan
unless (params[:plan] == '1' || params[:plan] == '2')
flash[:notice] = "Please select a membership plan to sign up."
redirect_to root_url
end
end
end
User model:
class User < ApplicationRecord
before_create :confirmation_token
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
belongs_to :plan
has_one :profile
attr_accessor :stripe_card_token
# If Pro user passes the validation for email, password etc. then call Stripe
# and tell Stripe to add a subscription by charging customer's card
# Stripe then returns a customer token in response
# Store the token id as customer id and save the user
def save_with_subscription
if valid?
customer = Stripe::Customer.create(description: email, plan: plan_id, card: stripe_card_token)
self.stripe_customer_token = customer.id
save!
end
end
private
def confirmation_token
if self.confirm_token.blank?
self.confirm_token = SecureRandom.urlsafe_base64.to_s
end
end
def email_activate
self.email_confirmed = true
self.confirm_token = nil
save!(:validate => false)
end
end
Anyone has any idea of sending the email confirmation email from devise controller? Thanks in advance!!!

Answer 1

While using devise we can solve the super do requirements in many ways, like
adding an after_create action in the User model to send a confirmation email.
But I think this solution is handy is you really need to work in with the super do your action with the devise registration controller.
Add the codes after the resource saves.
class Users::RegistrationsController < Devise::RegistrationsController
def create
super do |resource|
# Your super codes here
resource.save
yield resource if block_given?
if resource.persisted?
# We know that the user has been persisted to the database, so now we can send our mail to the resource(user) now!
UserMailer.registration_confirmation(resource).deliver
# ....
end
# ....
end
end
# .....
end
Make sure no double rendering or multi redirect is implied with the devise
