46 ''' mail_thread model is meant to be inherited by any model that needs to
47 act as a discussion topic on which messages can be attached. Public
48 methods are prefixed with ``message_`` in order to avoid name
49 collisions with methods of the models that will inherit from this class.
51 ``mail.thread`` defines fields used to handle and display the
52 communication history. ``mail.thread`` also manages followers of
53 inheriting classes. All features and expected behavior are managed
54 by mail.thread. Widgets has been designed for the 7.0 and following
57 Inheriting classes are not required to implement any method, as the
58 default implementation will work for any model. However it is common
59 to override at least the ``message_new`` and ``message_update``
60 methods (calling ``super``) to add model-specific behavior at
61 creation and update of a thread when processing incoming emails.
