Unable to display username in emails with action mailer

Question

I am trying to do something extremely simple, which is display username on the registration email. However it's outputting a blank space instead of displaying the user. I have just setup ActionMailer and everything else I have done works fine.

Code from register template:

<%= @user.name %>,

Thank you for registering!

Code from user_mailer.rb:

  def registration_confirmation(user)
    @user = user
    mail(:to => user.email, :subject => "Registered")
  end

Answer 1

在尝试这样的事情：

mail(:to => "#{user.name}<#{user.email}>", :subject => "Registered")
