Many sites need to notify users when certain events have occurred and to allow configurable options as to how those notifications are to be received.

The project aims to provide a Django app for this sort of functionality. This includes:

• Submission of notification messages by other apps.
• Automated generation of notice types defined in your settings.
• Automated Notification settings view.
• Automated Notification settings view for each type of observed object.
• Automated Notification messages with Automated hyperlink integration.
• Automated Notification message modification for observed objects.
• Automated deletion of Notification messages when observed object is deleted.
• Automated mark notice as seen when link is clicked.
• Unsubscribe links.
• Optional Notification Queuing.
• Optional Notification Threading.
• Pluggable backbends (configurable by user): -Notification messages via website. -Notification messages via email.

See the docs for installation help and all base django-notification features.

####1. Create notification types in your settings file:
No need to mess with management files in this version, its automated!

NOTICE_TYPES = [("commented","New Comment", "has commented on your pin"),]

Then run the management command to updated them as required:

python manage.py update_notice_types

Automation Note: Notice descriptions should take the form "has action on your object" where the object = content_type.name. The resulting notification will look like Username has commented on your object. Username & object will be converted to hyperlinks and clicking the object link will mark the notice as seen. However, the settings below will help you compensate when that is not possible. ####2. Configure other settings (see code for more details on how these work):
NOTIFICATION_CONTENT_TYPE_TRANSLATIONS: Provide the system any translations between content_type.name and the message text. IE: convert "profile_picture" to a hyperlink.

{'user':['profile picture', None(url if not = /content_type.name/)]}  

NOTIFICATION_OTHER_KEY_WORDS: Provide the system any other key words in message text that should be converted to hyperlinks. IE: convert "word" to a hyperlink.

{'word':'/url/'}

NOTIFICATION_CHECK_FOR_SENDER_NAMES: Provide the system any content_types that my mascarade as a variable word not rendered by default. IE: Given content_object.name = "post" will convert post.submitter to a hyperlink.

{'post':['submitter','/url/']}

OBSRVATION_DELETE_CONTENT_TYPES: Provide the system any content_type objects that are properties of the model. IE: Given content_object.name = "object" will delete the object object.propery1 and object.propery2 when any associated observations are deleted.

{'object':['property1', 'property2']}

OBSRVATION_AUTO_DELETE: True/False ####3. Send notifications to users (based on example code):

notification.send([target.submitter], "commented", {"from_user": user}, sender=target)

####4. Make some users observe the notification_type you created from some emitter (based on example code):

notification.observe(target, user, "commented")

####5. Send the notifications to users who are observing the sender (based on example code):

notification.send_observation_notices_for(target, "commented", {"from_user": user, "alter_desc":True, "owner":target.submitter}, [user, target.submitter], sender=target)

####6. Change the templates for each notification type to send personalized notifications:
This is not required if you use the automated features but feasible in certain cases.
####7. Display the notifications to the user:
Provide links to all the views provided.
####8. The code is heavily commented so please look through the code for more information.

@receiver(post_save, sender=Comment, dispatch_uid='comment.user')
def pin_comment_handler(sender, *args, **kwargs):
	comment = kwargs.pop('instance', None)
	user = comment.user
	target = comment.content_object
	from notification import models as notification
	#notify post's followers
	sent = notification.send_observation_notices_for(target, "commented", {"from_user": user, "alter_desc":True, "owner":target.submitter}, [user, target.submitter], sender=target)
	#notify user's followers
	notification.send_observation_notices_for(user, "commented", {"from_user": user, "alter_desc":True, "owner":target.submitter}, [user, target.submitter]+sent, sender=target)
	if user != target.submitter:
		#notify post's owner
		notification.send([target.submitter], "commented", {"from_user": user}, sender=target)
		#make comment user observe new comments for post.
		notification.observe(target, user, "commented")
