Why "Action Mailer" is not rendering the email template?

Question

I am using "Action Mailer" in Ruby on Rails application to send emails. I have the following action mailer:

class SecurityUserMailer < ActionMailer::Base

  default from: '[email protected]'

  def password_reset(security_user)
    @security_user = security_user
    mail to: security_user.email, subject: 'Password Reset'
  end

  def email_confirmation(security_user)
    @security_user = security_user
    mail to: security_user.email, subject: 'Account Created'
  end

end

I am successfully sending emails but the second method (email_confirmation) is not using the corresponding template.

The email templates are in views/security_users_mailer folder and named as follows:

1. email_confirmation.txt.erb
2. password_reset.txt.erb

Why only the password_reset template is used?

Note, firstly, I thought that maybe there is something wrong with the code in my template but then I replace it with text content and it is not rendered again.

Rails 4 I had this same issue, but mine was caused by having an empty layout in layouts/mailer.html.erb
