Send to multiple recipients in Rails with ActionMailer

Question

I'm trying to send multiple emails based on a boolean value in my database. The app is a simple scheduling app and user can mark their shift as "replacement_needed" and this should send out emails to all the users who've requested to receive these emails. Trouble is, it only every seems to send to one email. Here's my current code:

 def request_replacement(shift)
      @shift = shift
      @user = shift.user
      @recipients = User.where(:replacement_emails => true).all
      @url  = root_url
      @recipients.each do |r|
        @name = r.fname
        mail(:to => r.email,
           :subject => "A replacement clerk has been requested")
      end
  end

Answer 1

You can just send one email for multiple recipients like this.

def request_replacement(shift)
  @shift = shift
  @user = shift.user
  @recipients = User.where(:replacement_emails => true)
  @url  = root_url
  emails = @recipients.collect(&:email).join(",")
  mail(:to => emails, :subject => "A replacement clerk has been requested")
end

This will take all your @recipients email addresses and join them with ,. I think you can also pass an array to the :to key but not sure.

The only problem is you won't be able to use @name in your template. :(
