Question

In my ROR app, I am trying to send confirmation emails to my registered users when they signup, my website is on localhost currently. I am getting this error:

Answer 1

This is your user_mailer.rb

user_mailer.rb

class UserMailer < ActionMailer::Base
  def registration_confirmation(user)
    recipients   user.email
    from         "myemailid@gmail.com"
    subject      "Thank you for registration"
    body         :user => user  
  end

Try instead:

class UserMailer < ActionMailer::Base
  default from: "myemailid@gmail.com"

  def registration_confirmation(user)
    mail(to: user.email, subject: "Thank you for registration")
  end
end

And set up the appropriate view in views/user_mailer e.g. registration_confirmation.html.erb
