Here are a few guidelines that you should keep in mind during the addition of system notifications :
|
- avoid unnecessary content, swamping users with irrelevant messages will lead
|
||||||
|
to them ignoring all messages
|
||||||
- avoid unnecessary content; if a message has no interest, do not implement it
|
- use short sentences
|
||||||
- use short sentences
|
- do not include the document name, this is done by the thread widget

- do not include the document name, as it is managed by the thread widget

- use a simple and clean style

Subscription management

Subscription management

There are a few default subscription tricks that you should know before playing with subscription:
|
The default subscription behavior is the following:
|
||||||
|
|
||||||
- users that click on 'follow' follow the document. An entry in ``mail.subscription`` is created.
|
* Subscriptions are set up by creating a :class:`mail.followers`` entry
|
||||||
- users that click on 'unfollow' are no longer followers to the document. The related entry in ``mail.subscription`` is created.
|
* If a user creates or updates a document, they automatically follow it. The
|
||||||
- users that create or update a document automatically follow it. An entry in ``mail.subscription`` is created.
|
corresponding :class:`mail.followers` entry is created
|
||||||
|
* If a user explicitly cliks on the document's :guilabel:`Follow` button,
|
||||||
|
they follow the document. The corresponding :class:`mail.followers` entry
|
||||||
|
is created
|
||||||
|
* If a user explicitly clicks on the document's :guilabel:`Unfollow` button,
|
||||||
|
they stop following the document. The corresponding :class:`mail.followers`
|
||||||
|
entry is deleted
|
||||||
|
|
||||||
If you want to override this default behavior, you should avoid doing it manualle. You should instead override the ``message_get_subscribers`` method from mail.thread. The default implementation looks in the ``mail.suscription`` table for entries matching ``user_id=uid, res_model=self._name, res_id=current_record_id``. You can add subscribers by overriding the ``message_get_subscribers`` and adding user ids to the returned list. This means that they will be considered as followers even if they do not have an entry in the mail.subscription table.
|
You should not directly manipulate :class:`mail.followers` entry, if you need
|
||||||
|
to override the default subscription behavior you should override the relevant
|
||||||
|
:class:`mail.thread` methods.
|
||||||
|
|
||||||
As an exemple, let us say that you want to automatically add the my_task responsible along with the project manager to the list of followers. The method could look like:
|
.. TODO: wtf are the relevant mail.thread methds? message_get_subscribers
|
||||||
|
has disappeared and nothing looks like a replacement
|
||||||
::
|
|
||||||
|
|
||||||
def message_get_subscribers(self, cr, uid, ids, context=None):
|
|
||||||
# get the followers from the mail.subscription table
|
|
||||||
sub_ids = self.message_get_subscribers_ids(cr, uid, ids, context=context);
|
|
||||||
# add the employee and its manager if specified to the subscribed users
|
|
||||||
for obj in self.browse(cr, uid, ids, context=context):
|
|
||||||
if obj.user_id:
|
|
||||||
sub_ids.append(obj.user_id)
|
|
||||||
if obj.project_id and obj.project_id.user_id:
|
|
||||||
sub_ids.append(obj.project_id.user_id)
|
|
||||||
return self.pool.get('res.users').read(cr, uid, sub_ids, context=context)
|
|
||||||
|
|
||||||
This method has the advantage of being able to implement a particular behavior with as few code addition as possible. Moreover, when changing the task responsible of the project manager, the subscribers are always correct. This allows to avoid to implement complex corner cases that could obfuscate the code.
|
|
||||||
|
|
||||||
The drawback of this method is that it is no longer possible to those subscribers to unfollow a document. Indeed, as user ids are added directly in a list in ``message_get_subscribers``, it is not possible to unsubscribe to a document. However, this drawback is mitigated by
|
|
||||||
|
|
||||||
- only important users shoudl be added using this method. Important users should not unsubscribe from their documents.
|
|
||||||
- users can hide the notifications on their Wall
|
|
||||||
|
|
||||||
Messages display management
|
|
||||||
++++++++++++++++++++++++++++
|
|
||||||
|
|
||||||
By default, the mail_thread widget shows all messages related to the current document beside the document, in the History and comments section. However, you may want to display other messages in the widget. For example, the OpenChatter on res.users model shows
|
|
||||||
|
|
||||||
- messages related to the user, as usual (messages with ``model = res.users, res_id = current_document_id``)
|
|
||||||
- messages directly pushed to this user (containing @login)
|
|
||||||
|
|
||||||
The best way to direct the messages that will be displayed in the OpenChatter widget is to override the ``message_load`` method. For example, the following method fetches messages as usual, but also fetches messages linked to the task project that contain the task name. Please refer to the API for more details about the arguments.
|
|
||||||
|
|
||||||
::
|
|
||||||
|
|
||||||
def message_load(self, cr, uid, ids, limit=100, offset=0, domain=[], ascent=False, root_ids=[False], context=None):
|
|
||||||
msg_obj = self.pool.get('mail.message')
|
|
||||||
for my_task in self.browse(cr, uid, ids, context=context):
|
|
||||||
# search as usual messages related to the current document
|
|
||||||
msg_ids += msg_obj.search(cr, uid, ['|', '&', ('res_id', '=', my_task.id), ('model', '=', self._name),
|
|
||||||
# add: search in the current task project messages
|
|
||||||
'&', '&', ('res_id', '=', my_task.project_id.id), ('model', '=', 'project.project'),
|
|
||||||
# ... containing the task name
|
|
||||||
'|', ('body', 'like', '%s' % (my_task.name)), ('body_html', 'like', '%s' % (my_task.name))
|
|
||||||
] + domain, limit=limit, offset=offset, context=context)
|
|
||||||
# if asked: add ancestor ids to have complete threads
|
|
||||||
if (ascent): msg_ids = self._message_add_ancestor_ids(cr, uid, ids, msg_ids, root_ids, context=context)
|
|
||||||
return msg_obj.read(cr, uid, msg_ids, context=context)
