Files changed (1)

+This module provides an API to the django-postman application,
+for an easy usage from other applications in the project.
+Suppose an application managing Event objects. Whenever a new Event is generated,
+you want to broadcast an announcement to Users who have subscribed
+to be informed of the availability of such a kind of Event.
+from postman.api import pm_broadcast
+events = Event.objects.filter(...)
+for e in events:
+    pm_broadcast(
+        recipients=e.subscribers,
+        subject='New {0} at Our School: {1}'.format(e.type, e.title),
+        body=e.description)
+    from django.utils.timezone import now   # Django 1.4 aware datetimes
+except ImportError:
+    from datetime import datetime
+    now =
+from postman.models import Message, STATUS_PENDING, STATUS_ACCEPTED
+def pm_broadcast(sender, recipients, subject, body='', skip_notification=False):
+    """
+    Broadcast a message to multiple Users.
+    For an easier cleanup, all these messages are directly marked as archived and deleted on the sender side.
+    Optional argument:
+        ``skip_notification``: if the normal notification event is not wished
+    """
+    message = Message(subject=subject, body=body, sender=sender,
+        sender_archived=True, sender_deleted_at=now(),

+    if not isinstance(recipients, (tuple, list)):
+        recipients = (recipients,)
+    for recipient in recipients:
+        message.recipient = recipient

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
