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. :(

Answer 2

In the Rails guides (Action Mailer Basics) it says the following regarding multiple emails:

The list of emails can be an array of email addresses or a single string with the addresses separated by commas.

So both "[email protected], [email protected]" and ["[email protected]", "[email protected]"] should work.
