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.

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 from its default "localhost" setting. # * :port On the off chance 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 in this setting. # * :password If your mail server requires authentication, set the password in this setting. # * :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. # * default_content_type - 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 @content_type. # * default_mime_version - The default mime version used for the message. Defaults to nil. You # can also pick a different value from inside a method with @mime_version. When multipart messages are in # use, @mime_version will be set to "1.0" if it is not set inside a method. # * default_implicit_parts_order - 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 # @implicit_parts_order. class Base include AdvAttrAccessor, PartContainer 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 @@default_mime_version = nil cattr_accessor :default_mime_version @@default_implicit_parts_order = [ "text/html", "text/enriched", "text/plain" ] cattr_accessor :default_implicit_parts_order # Specify the BCC addresses for the message adv_attr_accessor :bcc # Define the body of the message.
