Each such detected template will be added as # # a separate part to the message. # # # # for example, if the following templates existed: # # * signup_notification.text.plain.rhtml # # * signup_notification.text.html.rhtml # # * signup_notification.text.xml.rxml # # * signup_notification.text.x-yaml.rhtml # # # # 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. # end # end # # # After this post_notification will look for "templates/application_mailer/post_notification.rhtml" # ApplicationMailer.template_root = "templates" # # ApplicationMailer.create_comment_notification(david, hello_world) # => a tmail object # ApplicationMailer.deliver_comment_notification(david, hello_world) # sends the email # # = Configuration options # # These options are specified on the class level, like ActionMailer::Base.template_root = "/my/templates" # # * template_root - template root determines the base from which template references will be made. # # * logger - 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. # # * server_settings - Allows detailed configuration of the server: # * :address Allows you to use a remote mail server. Just change it away from it's default "localhost" setting. # * :port On the off change that your mail server doesn't run on port 25, you can change it. # * :domain If you need to specify a HELO domain, you can do it here. # * :user_name If your mail server requires authentication, set the username and password in these two settings. # * :password If your mail server requires authentication, set the username and password in these two settings. # * :authentication 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 # # * raise_delivery_errors - whether or not errors should be raised if the email fails to be delivered. # # * delivery_method - Defines a delivery method. Possible values are :smtp (default), :sendmail, and :test. # Sendmail is assumed to be present at "/usr/sbin/sendmail". # # * perform_deliveries - Determines whether deliver_* methods are actually carried out. By default they are, # but this can be turned off to help functional testing. # # * deliveries - Keeps an array of all the emails sent out through the Action Mailer with delivery_method :test. Most useful # for unit and functional testing. # # * default_charset - 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 @charset. class Base include ActionMailer::AdvAttrAccessor private_class_method :new #:nodoc: cattr_accessor :template_root cattr_accessor :logger @@server_settings = { :address => "localhost", :port => 25, :domain => 'localhost.localdomain', :user_name => nil, :password => nil, :authentication => nil } cattr_accessor :server_settings @@raise_delivery_errors = true cattr_accessor :raise_delivery_errors @@delivery_method = :smtp cattr_accessor :delivery_method @@perform_deliveries = true cattr_accessor :perform_deliveries @@deliveries = [] cattr_accessor :deliveries @@default_charset = "utf-8" cattr_accessor :default_charset @@default_content_type = "text/plain" cattr_accessor :default_content_type adv_attr_accessor :recipients, :subject, :body, :from, :sent_on, :headers, :bcc, :cc, :charset, :content_type, :template attr_reader :mail # Instantiate a new mailer object.
