Current activity types master data cannot be unlinked through a quite harsh
override of unlink using xml id existence, introduced at 2602642a78dff6c15d615fadf4c55a6b6ca315df.
Some of them are real master data, other could be unlinked if users want it.
Finally custom activity types may cause errors when removed if used in some
side models like server actions or automated actions.
To allow more flexibility we remove the removal constraint and implement
a fallback mechanism. It is implemented in mail.activity.mixin when calling
activity_schedule(xmlid, ...). If the given xmlid is not found
_default_activity_type() specifies the default activity to use. It can
be overridden in modules if some specific behavior is wanted.
e.g.
def _default_activity_type(self):
"""Define a default fallback activity type when xml id not found
only used in in activity_schedule() for now.
"""
try:
return self.env.ref('mail.mail_activity_data_todo')
except Exception:
return False
In this commit we also
* restrict deletion of activity type (hr.plan and ir.actions.server);
* fallback on default activity type if xmlid ref not found in
activity_schedule;
* correct calls to activity_schedule and replace some manual creation calls
by activity_schedule;
