How do I add instance variables to Devise email templates?

Question

I am trying to edit the confirmation_instructions.html.erb file to address the new user by first name instead of email.

Current the beginning of the file reads...

Hi, <%= @email %>,

How do I add an instance variable @first_name to the controller/mailer?

I ran rails generate devise:controllers users, but I just don't see any .rb files where I could add instance variables to confirmation mailer (if there is one)

Thanks

This is easy, you can just create a Mailer for this:

class ConfirmationsMailer < Devise::Mailer
  default from: '<[email protected]>'

  def confirmation_instructions(record, token, opts={})
   @token = token
   #you can add your instance variables here
   devise_mail(record, :confirmation_instructions, opts)
  end
end

And then just tell Devise to use this class:

config/initializers/devise.rb

Devise.setup do |config|
...
config.mailer = 'ConfirmationsMailer'
...
end

Restart your server, and you should be good to go!

Can you give me an example of how to get an attribute from the user model? For instance the following isnt working @first_name = current_user.first_name – Clip

Instead of using current_user, you can just use the record argument from the method, so in your case @first_name = record.first_name – Strawn

i came here to say that I figured it out with @first_name = record.first_name and then saw your post. thanks for your help – Clip

where would I find what is available in the opts={} – Clip

You can find it in here github.com/plataformatec/devise/blob/… but is basically the headers for the email, for example subject, from, to, etc – Strawn

thanks. I also noticed you can change the subject in the devise lcoal file – Clip

You are welcome! If you found the answer useful show me some love by accept it :) thanks – Strawn
