Rails ActionMailer - format sender and recipient name/email address

问题

Is there a way to specify email AND name for sender and recipient info when using ActionMailer?

Typically you'd do:

@recipients   = "#{user.email}"
@from         = "info@mycompany.com"
@subject      = "Hi"
@content_type = "text/html"

But, I want to specify name as well-- MyCompany <info@mycompany.com>, John Doe <john.doe@mycompany>.

Is there a way to do that?

回答1:

If you are taking user input for name and email, then unless you very carefully validate or escape the name and email, you can end up with an invalid From header by simply concatenating strings. Here is a safe way:

require 'mail'
address = Mail::Address.new email # ex: "john@example.com"
address.display_name = name.dup   # ex: "John Doe"
# Set the From or Reply-To header to the following:
address.format # returns "John Doe <john@example.com>"

@recipients   = "\"#{user.name}\" <#{user.email}>"
@from         = "\"MyCompany\" <info@mycompany.com>"

In rails3 I place the following in each environment. i.e. production.rb

ActionMailer::Base.default :from => "Company Name <no-reply@production-server.ca>"

Placing quotations around the company name did not work for me in Rails3.

within Rails 2.3.3 a bug within the ActionMailer was introduced. You can see the ticket over here Ticket #2340. It's resolved in 2-3-stable and master so it will be fixed in 3.x and 2.3.6.

For fixing the problem within 2.3.* you can use the code provided within the ticket comments:

module ActionMailer
  class Base
    def perform_delivery_smtp(mail)
      destinations = mail.destinations
      mail.ready_to_send
      sender = (mail['return-path'] && mail['return-path'].spec) || Array(mail.from).first

      smtp = Net::SMTP.new(smtp_settings[:address], smtp_settings[:port])
      smtp.enable_starttls_auto if smtp_settings[:enable_starttls_auto] && smtp.respond_to?(:enable_starttls_auto)
      smtp.start(smtp_settings[:domain], smtp_settings[:user_name], smtp_settings[:password],
                 smtp_settings[:authentication]) do |smtp|
        smtp.sendmail(mail.encoded, sender, destinations)
      end
    end
  end
end

The version I like to use of this is

%`"#{account.full_name}" <#{account.email}>`

` << are backticks.

Update

You could also change that to

%|"#{account.full_name}" <#{account.email}>|
%\"#{account.full_name}" <#{account.email}>\
%^"#{account.full_name}" <#{account.email}>^
%["#{account.full_name}" <#{account.email}>]

Another irritating aspect, at least with the new AR format, is to remember that 'default' is called on the class level. Referencing routines that are instance-only causes it to silently fail and give when you try to use it:

 NoMethodError: undefined method `new_post' for Notifier:Class

Here's what I ended up using:

def self.named_email(name,email) "\"#{name}\" <#{email}>" end
default :from => named_email(user.name, user.email)
