module ActionMailer #:nodoc:
# ActionMailer allows you to send email from your application using a mailer model and views.
#
#
# = Mailer Models
#
# To use ActionMailer, you need to create a mailer model.
#
# $ script/generate mailer Notifier
#
# The generated model inherits from ActionMailer::Base. Emails are defined by creating methods within the model which are then
# used to set variables to be used in the mail template, to change options on the mail, or
# to add attachments.
#
# Examples:
#
# class Notifier < ActionMailer::Base
# def signup_notification(recipient)
# recipients recipient.email_address_with_name
# from "system@example.com"
# subject "New account information"
# body :account => recipient
# end
# end
#
# Mailer methods have the following configuration methods available.
#
# * <tt>recipients</tt> - Takes one or more email addresses. These addresses are where your email will be delivered to. Sets the <tt>To:</tt> header.
# * <tt>subject</tt> - The subject of your email. Sets the <tt>Subject:</tt> header.
# * <tt>from</tt> - Who the email you are sending is from. Sets the <tt>From:</tt> header.
# * <tt>cc</tt> - Takes one or more email addresses. These addresses will receive a carbon copy of your email. Sets the <tt>Cc:</tt> header.
# * <tt>bcc</tt> - Takes one or more email address. These addresses will receive a blind carbon copy of your email. Sets the <tt>Bcc</tt> header.
# * <tt>sent_on</tt> - The date on which the message was sent. If not set, the header wil be set by the delivery agent.
# * <tt>content_type</tt> - Specify the content type of the message. Defaults to <tt>text/plain</tt>.
# * <tt>headers</tt> - Specify additional headers to be set for the message, e.g. <tt>headers 'X-Mail-Count' => 107370</tt>.
#
# The <tt>body</tt> method has special behavior. It takes a hash which generates an instance variable
# named after each key in the hash containing the value that that key points to.
#
# So, for example, <tt>body "account" => recipient</tt> would result
# in an instance variable <tt>@account</tt> with the value of <tt>recipient</tt> being accessible in the
# view.
#
#
# = Mailer views
#
# Like ActionController, each mailer class has a corresponding view directory
# in which each method of the class looks for a template with its name.
# To define a template to be used with a mailing, create an <tt>.erb</tt> file with the same name as the method
# in your mailer model. For example, in the mailer defined above, the template at
# <tt>app/views/notifier/signup_notification.erb</tt> would be used to generate the email.
#
# Variables defined in the model are accessible as instance variables in the view.
#
# Emails by default are sent in plain text, so a sample view for our model example might look like this:
#
# Hi <%= @account.name %>,
# Thanks for joining our service! Please check back often.
#
# You can even use Action Pack helpers in these views. For example:
#
# You got a new note!
# <%= truncate(note.body, 25) %>
#
#
# = Generating URLs for mailer views
#
# If your view includes URLs from the application, you need to use url_for in the mailing method instead of the view.
# Unlike controllers from Action Pack, the mailer instance doesn't have any context about the incoming request. That's
# why you need to jump this little hoop and supply all the details needed for the URL. Example:
#
# def signup_notification(recipient)
# recipients recipient.email_address_with_name
# from "system@example.com"
# subject "New account information"
# body :account => recipient,
# :home_page => url_for(:host => "example.com", :controller => "welcome", :action => "greeting")
# end
#
# You can now access @home_page in the template and get http://example.com/welcome/greeting.
#
# = Sending mail
#
# Once a mailer action and template are defined, you can deliver your message or create it and save it
# for delivery later:
#
# Notifier.deliver_signup_notification(david) # sends the email
# mail = Notifier.create_signup_notification(david) # => a tmail object
# Notifier.deliver(mail)
#
# You never instantiate your mailer class. Rather, your delivery instance
# methods are automatically wrapped in class methods that start with the word
# <tt>deliver_</tt> followed by the name of the mailer method that you would
# like to deliver. The <tt>signup_notification</tt> method defined above is
# delivered by invoking <tt>Notifier.deliver_signup_notification</tt>.
#
#
# = HTML email
#
# To send mail as HTML, make sure your view (the <tt>.erb</tt> file) generates HTML and
# set the content type to html.
#
# class MyMailer < ActionMailer::Base
# def signup_notification(recipient)
# recipients recipient.email_address_with_name
# subject "New account information"
# body "account" => recipient
# from "system@example.com"
# content_type "text/html" # Here's where the magic happens
# end
# end
#
#
# = Multipart email
#
# You can explicitly specify multipart messages:
#
# class ApplicationMailer < ActionMailer::Base
# def signup_notification(recipient)
# recipients recipient.email_address_with_name
# subject "New account information"
# from "system@example.com"
#
# part :content_type => "text/html",
# :body => render_message("signup-as-html", :account => recipient)
#
# part "text/plain" do |p|
# p.body = render_message("signup-as-plain", :account => recipient)
# p.transfer_encoding = "base64"
# end
# end
# end
#
# Multipart messages can also be used implicitly because ActionMailer will automatically
# detect and use multipart templates, where each template is named after the name of the action, followed
# by the content type. Each such detected template will be added as separate part to the message.
#
# For example, if the following templates existed:
# * signup_notification.text.plain.erb
# * signup_notification.text.html.erb
# * signup_notification.text.xml.builder
# * signup_notification.text.x-yaml.erb
#
# Each would be rendered and added as a separate part to the message,
# with the corresponding content type. The same body hash is passed to
# each template.
#
#
# = Attachments
#
# Attachments can be added by using the +attachment+ method.
#
# Example:
#
# class ApplicationMailer < ActionMailer::Base
# # attachments
# def signup_notification(recipient)
# recipients recipient.email_address_with_name
# subject "New account information"
# from "system@example.com"
#
# attachment :content_type => "image/jpeg",
# :body => File.read("an-image.jpg")
#
# attachment "application/pdf" do |a|
# a.body = generate_your_pdf_here()
# end
# end
# end
#
#
# = Configuration options
#
# These options are specified on the class level, like <tt>ActionMailer::Base.template_root = "/my/templates"</tt>
#
# * <tt>template_root</tt> - template root determines the base from which template references will be made.
#
# * <tt>logger</tt> - the logger is used for generating information on the mailing run if available.
# Can be set to nil for no logging. Compatible with both Ruby's own Logger and Log4r loggers.
#
# * <tt>smtp_settings</tt> - Allows detailed configuration for :smtp delivery method:
# * <tt>:address</tt> Allows you to use a remote mail server. Just change it from its default "localhost" setting.
# * <tt>:port</tt> On the off chance that your mail server doesn't run on port 25, you can change it.
# * <tt>:domain</tt> If you need to specify a HELO domain, you can do it here.
# * <tt>:user_name</tt> If your mail server requires authentication, set the username in this setting.
# * <tt>:password</tt> If your mail server requires authentication, set the password in this setting.
# * <tt>:authentication</tt> If your mail server requires authentication, you need to specify the authentication type here.
# This is a symbol and one of :plain, :login, :cram_md5
#
# * <tt>sendmail_settings</tt> - Allows you to override options for the :sendmail delivery method
# * <tt>:location</tt> The location of the sendmail executable, defaults to "/usr/sbin/sendmail"
# * <tt>:arguments</tt> The command line arguments
# * <tt>raise_delivery_errors</tt> - whether or not errors should be raised if the email fails to be delivered.
#
# * <tt>delivery_method</tt> - Defines a delivery method. Possible values are :smtp (default), :sendmail, and :test.
#
# * <tt>perform_deliveries</tt> - Determines whether deliver_* methods are actually carried out. By default they are,
# but this can be turned off to help functional testing.
#
# * <tt>deliveries</tt> - Keeps an array of all the emails sent out through the Action Mailer with delivery_method :test. Most useful
# for unit and functional testing.
#
# * <tt>default_charset</tt> - The default charset used for the body and to encode the subject. Defaults to UTF-8. You can also
# pick a different charset from inside a method with <tt>@charset</tt>.
# * <tt>default_content_type</tt> - The default content type used for the main part of the message. Defaults to "text/plain". You
# can also pick a different content type from inside a method with <tt>@content_type</tt>.
# * <tt>default_mime_version</tt> - The default mime version used for the message. Defaults to "1.0". You
# can also pick a different value from inside a method with <tt>@mime_version</tt>.
# * <tt>default_implicit_parts_order</tt> - When a message is built implicitly (i.e. multiple parts are assembled from templates
# which specify the content type in their filenames) this variable controls how the parts are ordered. Defaults to
# ["text/html", "text/enriched", "text/plain"]. Items that appear first in the array have higher priority in the mail client
# and appear last in the mime encoded message. You can also pick a different order from inside a method with
# <tt>@implicit_parts_order</tt>.
