|

# Action Mailer allows you to send email from your application using a mailer
|
||||
# model and views.
|

#
|
||||
# == Mailer Models
|
||||
#
|
||||
# To use Action Mailer, you need to create a mailer model.
|
||||
#
|
||||
# $ rails generate mailer Notifier
|
||||
#
|
||||
# The generated model inherits from <tt>ActionMailer::Base</tt>. A mailer model defines methods
|
||||
# used to generate an email message. In these methods, you can setup variables to be used in
|
||||
# the mailer views, options on the mail itself such as the <tt>:from</tt> address, and attachments.

# model defines methods used to generate an email message. In these methods,
|
||||
# you can setup variables to be used in the mailer views, options on the mail
|
||||
# itself such as the <tt>:from</tt> address, and attachments.
|
||||
#
|
||||
# Examples:
|
||||
#
|
||||
# class Notifier < ActionMailer::Base
|
||||
# default :from => 'no-reply@example.com',
|
||||
# :return_path => 'system@example.com'
|
||||
# default from: 'no-reply@example.com',
|
||||
# return_path: 'system@example.com'
|
||||
#
|
||||
# def welcome(recipient)
|
||||
# @account = recipient
|
||||
# mail(:to => recipient.email_address_with_name,
|
||||
# :bcc => ["bcc@example.com", "Order Watcher <watcher@example.com>"])
|
||||
# mail(to: recipient.email_address_with_name,
|
||||
# bcc: ['bcc@example.com', 'Order Watcher <watcher@example.com>'])
|

# end
|

# end
|
||||
#
|
||||
# Within the mailer method, you have access to the following methods:
|
||||
#
|
||||
# * <tt>attachments[]=</tt> - Allows you to add attachments to your email in an intuitive

|

|
||||
# your email in the same manner as <tt>attachments[]=</tt>.
|
||||
#
|

# * <tt>headers[]=</tt> - Allows you to specify any header field in your email such
|
||||
# as <tt>headers['X-No-Spam'] = 'True'</tt>. Note, while most fields like <tt>To:</tt>
|
||||
# <tt>From:</tt> can only appear once in an email header, other fields like <tt>X-Anything</tt>
|
||||
# can appear multiple times. If you want to change a field that can appear multiple times,
|
||||
# you need to set it to nil first so that Mail knows you are replacing it and not adding

#
|
