module ActionMailer #:nodoc:
# 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>. 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
# 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>"])
# 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
# manner; <tt>attachments['filename.png'] = File.read('path/to/filename.png')</tt>
#
# * <tt>attachments.inline[]=</tt> - Allows you to add an inline attachment to 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, not adding
# another field of the same name.)
#
# * <tt>headers(hash)</tt> - Allows you to specify multiple headers in your email such
# as <tt>headers({'X-No-Spam' => 'True', 'In-Reply-To' => '1234@message.id'})</tt>
#
# * <tt>mail</tt> - Allows you to specify your email to send.
#
# The hash passed to the mail method allows you to specify any header that a Mail::Message
# will accept (any valid Email header including optional fields).
#
# The mail method, if not passed a block, will inspect your views and send all the views with
# the same name as the method, so the above action would send the +welcome.text.plain.erb+ view
# file as well as the +welcome.text.html.erb+ view file in a +multipart/alternative+ email.
#
# If you want to explicitly render only certain templates, pass a block:
#
# mail(:to => user.email) do |format|
# format.text
# format.html
# end
#
# The block syntax is useful if also need to specify information specific to a part:
#
# mail(:to => user.email) do |format|
# format.text(:content_transfer_encoding => "base64")
# format.html
# end
#
# Or even to render a special view:
#
# mail(:to => user.email) do |format|
# format.text
# format.html { render "some_other_template" }
# end
#
# = Mailer views
#
# Like Action Controller, 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.text.plain.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) %>
#
# If you need to access the subject, from or the recipients in the view, you can do that through message object:
#
# You got a new note from <%= message.from %>!
# <%= truncate(@note.body, 25) %>
#
#
# = Generating URLs
#
# URLs can be generated in mailer views using <tt>url_for</tt> or named routes. Unlike controllers from
# Action Pack, the mailer instance doesn't have any context about the incoming request, so you'll need
# to provide all of the details needed to generate a URL.
#
# When using <tt>url_for</tt> you'll need to provide the <tt>:host</tt>, <tt>:controller</tt>, and <tt>:action</tt>:
#
# <%= url_for(:host => "example.com", :controller => "welcome", :action => "greeting") %>
#
# When using named routes you only need to supply the <tt>:host</tt>:
#
# <%= users_url(:host => "example.com") %>
#
# You will want to avoid using the <tt>name_of_route_path</tt> form of named routes because it doesn't
# make sense to generate relative URLs in email messages.
#
# It is also possible to set a default host that will be used in all mailers by setting the <tt>:host</tt>
# option in the <tt>ActionMailer::Base.default_url_options</tt> hash as follows:
#
# ActionMailer::Base.default_url_options[:host] = "example.com"
#
# This can also be set as a configuration option in <tt>config/environment.rb</tt>:
#
# config.action_mailer.default_url_options = { :host => "example.com" }
#
# If you do decide to set a default <tt>:host</tt> for your mailers you will want to use the
# <tt>:only_path => false</tt> option when using <tt>url_for</tt>. This will ensure that absolute URLs are
# generated because the <tt>url_for</tt> view helper will, by default, generate relative URLs when a
# <tt>:host</tt> option isn't explicitly provided.
#
# = 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.welcome(david).deliver # sends the email
# mail = Notifier.welcome(david) # => a Mail::Message object
# mail.deliver # sends the email
#
# You never instantiate your mailer class. Rather, you just call the method you defined on the class itself.
#
# = Multipart Emails
#
# Multipart messages can also be used implicitly because Action Mailer 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.yaml.erb
#
# Each would be rendered and added as a separate part to the message, with the corresponding content
# type. The content type for the entire message is automatically set to <tt>multipart/alternative</tt>,
# which indicates that the email contains multiple different representations of the same email
# body. The same instance variables defined in the action are passed to all email templates.
#
# Implicit template rendering is not performed if any attachments or parts have been added to the email.
# This means that you'll have to manually add each part to the email and set the content type of the email
# to <tt>multipart/alternative</tt>.
#
# = Attachments
#
# You can see above how to make a multipart HTML / Text email, to send attachments is just
# as easy:
#
# class ApplicationMailer < ActionMailer::Base
# def welcome(recipient)
# attachments['free_book.pdf'] = File.read('path/to/file.pdf')
# mail(:to => recipient, :subject => "New account information")
# end
# end
#
# Which will (if it had both a <tt>welcome.text.plain.erb</tt> and <tt>welcome.text.html.erb</tt>
# template in the view directory), send a complete <tt>multipart/mixed</tt> email with two parts,
# the first part being a <tt>multipart/alternative</tt> with the text and HTML email parts inside,
# and the second being a <tt>application/pdf</tt> with a Base64 encoded copy of the file.pdf book
# with the filename +free_book.pdf+.
#
# = Inline Attachments
#
# You can also specify that a file should be displayed inline with other HTML. For example a
# corporate logo or a photo or the like.
#
# To do this is simple, in the Mailer:
#
# class ApplicationMailer < ActionMailer::Base
# def welcome(recipient)
# attachments.inline['photo.png'] = File.read('path/to/photo.png')
# mail(:to => recipient, :subject => "Here is what we look like")
# end
# end
#
# And then to reference the image in the view, you create a <tt>welcome.html.erb</tt> file and
# make a call to +image_tag+ passing in the attachment you want to display and then call
# +url+ on the attachment to get the relative content id path for the image source:
#
# <h1>Please Don't Cringe</h1>
#
# <%= image_tag attachments['photo.png'].url -%>
#
# As we are using Action View's +image_tag+ method, you can pass in any other options you want:
#
# <h1>Please Don't Cringe</h1>
#
# <%= image_tag attachments['photo.png'].url, :alt => 'Our Photo', :class => 'photo' -%>
#
# = Observing and Intercepting Mails
#
# Action Mailer provides hooks into the Mail observer and interceptor methods. These allow you to
# register objects that are called during the mail delivery life cycle.
#
# An observer object must implement the <tt>:delivered_email(message)</tt> method which will be
# called once for every email sent after the email has been sent.
#
# An interceptor object must implement the <tt>:delivering_email(message)</tt> method which will be
# called before the email is sent, allowing you to make modifications to the email before it hits
# the delivery agents. Your object should make and needed modifications directly to the passed
# in Mail::Message instance.
#
# = Default Hash
#
# Action Mailer provides some intelligent defaults for your emails, these are usually specified in a
# default method inside the class definition:
#
# class Notifier < ActionMailer::Base
# default :sender => 'system@example.com'
# end
#
# You can pass in any header value that a <tt>Mail::Message</tt>, out of the box, <tt>ActionMailer::Base</tt>
# sets the following:
#
# * <tt>:mime_version => "1.0"</tt>
# * <tt>:charset => "UTF-8",</tt>
# * <tt>:content_type => "text/plain",</tt>
# * <tt>:parts_order => [ "text/plain", "text/enriched", "text/html" ]</tt>
#
# <tt>parts_order</tt> and <tt>charset</tt> are not actually valid <tt>Mail::Message</tt> header fields,
# but Action Mailer translates them appropriately and sets the correct values.
#
# As you can pass in any header, you need to either quote the header as a string, or pass it in as
# an underscorised symbol, so the following will work:
#
# class Notifier < ActionMailer::Base
# default 'Content-Transfer-Encoding' => '7bit',
# :content_description => 'This is a description'
# end
#
# Finally, Action Mailer also supports passing <tt>Proc</tt> objects into the default hash, so you
# can define methods that evaluate as the message is being generated:
#
# class Notifier < ActionMailer::Base
# default 'X-Special-Header' => Proc.new { my_method }
#
# private
#
# def my_method
# 'some complex call'
# end
# end
#
# Note that the proc is evaluated right at the start of the mail message generation, so if you
# set something in the defaults using a proc, and then set the same thing inside of your
# mailer method, it will get over written by the mailer method.
#
# = Configuration options
#
# These options are specified on the class level, like
# <tt>ActionMailer::Base.template_root = "/my/templates"</tt>
#
# * <tt>default</tt> - You can pass this in at a class level as well as within the class itself as
# per the above section.
#
# * <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 <tt>:smtp</tt> 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 <tt>:plain</tt>, <tt>:login</tt>, <tt>:cram_md5</tt>.
# * <tt>:enable_starttls_auto</tt> - When set to true, detects if STARTTLS is enabled in your SMTP server
# and starts to use it.
#
# * <tt>sendmail_settings</tt> - Allows you to override options for the <tt>:sendmail</tt> delivery method.
# * <tt>:location</tt> - The location of the sendmail executable. Defaults to <tt>/usr/sbin/sendmail</tt>.
# * <tt>:arguments</tt> - The command line arguments. Defaults to <tt>-i -t</tt> with <tt>-f sender@addres</tt>
# added automatically before the message is sent.
#
# * <tt>file_settings</tt> - Allows you to override options for the <tt>:file</tt> delivery method.
# * <tt>:location</tt> - The directory into which emails will be written. Defaults to the application
# <tt>tmp/mails</tt>.
#
# * <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 <tt>:smtp</tt> (default),
# <tt>:sendmail</tt>, <tt>:test</tt>, and <tt>:file</tt>. Or you may provide a custom delivery method
# object eg. MyOwnDeliveryMethodClass.new. See the Mail gem documentation on the interface you need to
# implement for a custom delivery agent.
#
# * <tt>perform_deliveries</tt> - Determines whether emails are actually sent from Action Mailer when you
# call <tt>.deliver</tt> on an mail message or on an Action Mailer method. This is on by default but can
# be turned off to aid in functional testing.
#
# * <tt>deliveries</tt> - Keeps an array of all the emails sent out through the Action Mailer with
# <tt>delivery_method :test</tt>. Most useful for unit and functional testing.
#
# * <tt>default_charset</tt> - This is now deprecated, use the +default+ method above to
# set the default +:charset+.
#
# * <tt>default_content_type</tt> - This is now deprecated, use the +default+ method above
# to set the default +:content_type+.
#
# * <tt>default_mime_version</tt> - This is now deprecated, use the +default+ method above
# to set the default +:mime_version+.
#
# * <tt>default_implicit_parts_order</tt> - This is now deprecated, use the +default+ method above
# to set the default +:parts_order+. Parts Order is used 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.

# mail.attachments['filename.jpg'] = {:mime_type => 'application/x-gzip',

#

# but then it is up to you to pass in the content pre-encoded, and don't expect
# Mail to know how to decode this data:
#
# file_content = SpecialEncode(File.read('/path/to/filename.jpg'))
# mail.attachments['filename.jpg'] = {:mime_type => 'application/x-gzip',
# :encoding => 'SpecialEncoding',
# :content => file_content }
#
# You can also search for specific attachments:
#
# # By Filename
# mail.attachments['filename.jpg'] #=> Mail::Part object or nil
#
# # or by index
# mail.attachments[0] #=> Mail::Part (first attachment)
#
def attachments
@_message.attachments
end
# The main method that creates the message and renders the email templates. There are
# two ways to call this method, with a block, or without a block.
#
# Both methods accept a headers hash. This hash allows you to specify the most used headers
# in an email message, these are:
#
# * <tt>:subject</tt> - The subject of the message, if this is omitted, Action Mailer will
# ask the Rails I18n class for a translated <tt>:subject</tt> in the scope of
# <tt>[:actionmailer, mailer_scope, action_name]</tt> or if this is missing, will translate the
# humanized version of the <tt>action_name</tt>
# * <tt>:to</tt> - Who the message is destined for, can be a string of addresses, or an array
# of addresses.
# * <tt>:from</tt> - Who the message is from
# * <tt>:cc</tt> - Who you would like to Carbon-Copy on this email, can be a string of addresses,
# or an array of addresses.
# * <tt>:bcc</tt> - Who you would like to Blind-Carbon-Copy on this email, can be a string of
# addresses, or an array of addresses.
# * <tt>:reply_to</tt> - Who to set the Reply-To header of the email to.
# * <tt>:date</tt> - The date to say the email was sent on.
#
# You can set default values for any of the above headers (except :date) by using the <tt>default</tt>
# class method:
#
# class Notifier < ActionMailer::Base
# self.default :from => 'no-reply@test.lindsaar.net',
# :bcc => 'email_logger@test.lindsaar.net',
# :reply_to => 'bounces@test.lindsaar.net'
# end
#
# If you need other headers not listed above, use the <tt>headers['name'] = value</tt> method.
#
# When a <tt>:return_path</tt> is specified as header, that value will be used as the 'envelope from'
# address for the Mail message. Setting this is useful when you want delivery notifications
# sent to a different address than the one in <tt>:from</tt>. Mail will actually use the
# <tt>:return_path</tt> in preference to the <tt>:sender</tt> in preference to the <tt>:from</tt>
# field for the 'envelope from' value.
#
# If you do not pass a block to the +mail+ method, it will find all templates in the
# view paths using by default the mailer name and the method name that it is being
# called from, it will then create parts for each of these templates intelligently,
# making educated guesses on correct content type and sequence, and return a fully
# prepared Mail::Message ready to call <tt>:deliver</tt> on to send.
#
# For example:
#
# class Notifier < ActionMailer::Base
# default :from => 'no-reply@test.lindsaar.net',
#
# def welcome
# mail(:to => 'mikel@test.lindsaar.net')
# end
# end
#
# Will look for all templates at "app/views/notifier" with name "welcome". However, those
# can be customized:
#
# mail(:template_path => 'notifications', :template_name => 'another')
#
# And now it will look for all templates at "app/views/notifications" with name "another".
#
# If you do pass a block, you can render specific templates of your choice:
#
# mail(:to => 'mikel@test.lindsaar.net') do |format|
# format.text
# format.html
# end
#
# You can even render text directly without using a template:
#
# mail(:to => 'mikel@test.lindsaar.net') do |format|
# format.text { render :text => "Hello Mikel!" }
# format.html { render :text => "<h1>Hello Mikel!</h1>" }
# end
#
# Which will render a <tt>multipart/alternative</tt> email with <tt>text/plain</tt> and
# <tt>text/html</tt> parts.
#
# The block syntax also allows you to customize the part headers if desired:
#
# mail(:to => 'mikel@test.lindsaar.net') do |format|
# format.text(:content_transfer_encoding => "base64")
# format.html
