It works like the mail.thread mixin. It defines an activity_ids one2many field toward activities using res_id and res_model_id. Various related / computed fields are also added to have a global status of activities on documents. Activities come with a new JS widget for the form view. It is integrated in the Chatter widget although it is a separate widget. It displays activities linked to the current record and allow to schedule, edit and mark done activities. There is also a kanban widget defined. It defines a small widget to integrate in kanban vignettes. It allow to manage activities directly from the kanban view. Use widget="kanban_activity" on activitiy_ids field in kanban view to use it. Some context keys allow to control the mixin behavior. Use those in some specific cases like import * ``mail_activity_automation_skip``: skip activities automation; it means no automated activities will be generated, updated or unlinked, allowing to save computation and avoid generating unwanted activities; """ _name = 'mail.activity.mixin' _description = 'Activity Mixin' def _default_activity_type(self): """Define a default fallback activity type when requested xml id wasn't found.
