Facebook like notification updates using django signal or notification - django

How can i use django-notifications or django-signals to make something like facebook updates notification that shows in the user profile if any other user likes or posts comments on user's blog or posts?


For the activity feed, we use https://github.com/justquick/django-activity-stream Documentation: http://justquick.github.com/django-activity-stream/
For the js widget and live notifications, we use https://github.com/subsume/django-subscription yourlabs example, it depends on redis but you can easily add a model backend if you really want to. Redis is a good choices it's half a megabyte of dependency. Documentation: http://django-social.rtfd.org
There is no application that does meta-notifications ("notification groupping") properly but a lot of research has been done. Basically you need another app, with a MetaNotification model, and something (management command, signal ...) that will visit notifications and create MetaNotification instances. Then you should display MetaNotification lists rather than Activity or notification list.
Finnaly, if you want configurable email notifications then you can use django-notifications: https://github.com/jtauber/django-notification or this app which looks nicer: http://www.tomaz.me/django-notifications/
I'm not aware of any app that does it all. It is going to be some work for you.
"It's a long way to the top if you wanna rock'n'roll" or as I like to say "patience and perseverance" :)


https://pypi.python.org/pypi/feedly allows you to build newsfeed and notification systems using Cassandra and/or Redis. Examples of what you can build are applications like the Facebook newsfeed, your Twitter stream or your Pinterest following page.

how to create realtime notification in django without using django channels

For every action such as-
log in
sign up
password reset
Notifications should be seen to the user with a notification bell icon (just like Facebook)
where real-time notifications are shown according to each action performed.
Also, an email should be sent to that user.
Note - (YOU CAN USE ANY DJANGO LIBRARY EXCEPT DJANGO CHANNELS)
this is the question that I want to solve. please help me.

You can use the Google Firebase Cloud Messaging service. There a lot of packages that work with this service. I recommend you to use fcm-django package for simplicity.

What scaleable way to send notification emails in django?

On a custom django app I'd like to send notification email on many events, e.g. when a user's comment is being liked or comment is posted on her profile.
However I am worried that this will have scaling implications for the app so I am wondering what is the best way to do it so that it does not block the views.

Use Django-Celery to put it in a Task Queue, that way it all happens in the background.

How do I remove a Facebook app notification from the app?

If I post an app-to-user notification as per the docs (https://developers.facebook.com/docs/reference/api/user/#notifications), it does only have a 'Create' section in the docs, but I'm just wondering if there is any way I can then remove them, like you can with apprequests (https://developers.facebook.com/docs/reference/api/user/#apprequests)?
We're building a game which allows for random-user play, so need app-to-user communication, but don't want to use an app-to-user apprequest because they don't get notifications. But with app-to-user notifications, they clutter up notification list if you're not able to delete them from the app.
I know in you can call https://graph.facebook.com/me/notifications/, but you need the 'manage_notifications' extended permissions for that, which then gives you access to all your notifications, which we think is overkill and unnecessary.
Is there any other way?

IS there any Django app that notify the user about something that happened in your web, and ask him to perform an action?

I mean, there's any generic app that you can use to make notifications like when in Facebook, someone adds you as friend, or invite you to an event?
Basically, I need to show to the user this type of notification for different contents type, with the possibility to do some custom actions (ignore, accept, etc) different for each one.
I wonder if someone have done this before, so I can plug it and create a type of notification simply passing the text of the notification, the options that must show and the views to call for each option.
Thanks.

django-notifications is a GitHub notifications alike app, and it's based on Django Activity Stream.
If you familia with django-activity-stream, the the usage of django-notifications almost the same.
django-notifications also provide notifications_unread templatetag to display unread notifications of current login user.

Django Activity Stream does this, for the most part. It's a generic relationship manager that watches for save events in the datbase, and when a condition is met it puts an "event happened!" record into its own tables.
It would be incumbent upon you to then present that feed of events to the user, along with links to the actions (specific to your project) that you want him to take.
Even if it's not what you want, it's an excellent example of how to start.

Maybe this is more closer to my needs:
django-notification
https://github.com/jtauber/django-notification
any experience with that?

There is also django-notify: http://code.google.com/p/django-notify/

What Web Applications Do You Know Using Webhooks

Description of how a webhook works from http://webhooks.pbwiki.com/ -
How do they work?
By letting the user specify a URL for various events, the application will POST data to those URLs when the events occur...Among other things, you can:
create notifications to you or anybody via email, IRC, Jabber, ...
put the data in another app (real-time data synchronization)
process the data and repost it using the app's API
validate the data and potentially prevent it from being used by the app
Who is using web hooks?
DevjaVu, BitBucket, GitHub, Shopify, Versionshelf, PayPal (IPN), Jott (Links), IMified, PBwiki, Facebook (Platform, sort of), Mailhook.org, SMTP2Web, Astrotrain, Notifixious, Assembla, ZenDesk, Google Code
Do you know of any good uses of webhooks?

AlertGrid is the webhook consumer. You can configure it to accept http calls from ANY source and raise alert (email, sms, phone) to a specified person or group of people (works worldwide!) whenever the parameters in the http callback meet your criteria or when the http call was expected but it didn't occur (kind of 'heartbeat' monitoring). There is a visual editor for you to easily create rules.
Apart from notifying people by sms or email it can also notify existing applications by sending the http requests to their APIs.
It can also visualise data received in http callbacks and show the history.

Unfortunately, the wiki is not the most up to date list of known implementations. I have my own list that I'll put on the wiki when I get around to reorganizing it. Some not mentioned in the current list:
Dropbox
Gnip
Google Code (Project Hosting)
Checkout by Amazon (both for notifications and as actual callbacks with return data)
Hubilicious
Beanstalk
Google Checkout
MailChimp
SurveyGizmo
Hey!Watch
MySpace (for app developers)

I know shopify is using webhooks quite successfully now. By extension so is fetchapp uses them as well. You either are sending an xml file, or receiving one and doing your own processing logic on it.
Oh and shopify's wiki in the link has a whole write up about how to implement it in your app.

OfficeAutopilot has an interesting version of webhooks.. they use their rule interface to trigger API posts. Can trigger in response to any system event.. email opens, clicks, page visits, purchases, etc, etc.

Kiln 1.2 uses webhooks much like GitHub, BitBucket, etc.
(Disclaimer: I'm a Kiln/FogBugz dev.)

Say for example you want to get data from any API( eg. twitter, facebook etc.,). Instead of you polling the data for every few minutes/seconds, it POSTS the data to the specified URL, whenever it is available.
By using this, you will avoid unnecessary polling like say you poll and data is not there yet.

StorageRoom is a JSON-based CMS that supports webhooks, so that you can notify other services or kick of some manual processing on your own servers.
(Please note: I created the service myself)

If you want to connect one service that supports webhooks to another service's API, you can check out IronWorker's webhook support. Here's a blog post that walks through connecting github webhooks to HipChat:
http://blog.iron.io/2012/04/one-webhook-to-rule-them-all-one-url.html
There are some other examples here too, one that takes a chargify callback and posts to Campfire.
