Real time object access notifications via Pusher

Project description

# django-pusherable

Real-time object access notifications via [Pusher](

## Installation

Install django-pusherable:

pip install django-pusherable

## Configuration

Then add `pusherable` to your `INSTALLED_APPS`. You will also need to add your Pusher
app credentials to ``. These are available on your app keys page:


## Mixins

To begin receiving notifications about an object use the mixins:

from pusherable.mixins import PusherDetailMixin, PusherUpdateMixin

class PostDetail(PusherDetailMixin, DetailView):
model = Post

class PostUpdate(PusherUpdateMixin, UpdateView):
model = Post
form_class = PostUpdateForm

When the view is accessed it will send an event on the channel
`modelname_pk` which contains a JSON representation of the object (model instance)
being accessed as well as the user.

The data will be in the form:

"object": {
"question": "What's up?",
"pub_date": "2013-08-08T11:16:24",
"id": 1
"user": "admin"

Which fields are included and excluded within the `object` is configurable via
`pusher_include_model_fields` and `pusher_exclude_model_fields`. For example,
the following would exclude the `pub_date` from the event payload:

class PostUpdate(PusherUpdateMixin, UpdateView):
model = Post
form_class = PostUpdateForm
pusher_exclude_model_fields = 'pub_date'

## Template tags

To subscribe to these events on your page you can use the templatetags:

{% load pusherable_tags %}

{% pusherable_script %}

The `pusherable_script` tag will include the Pusher library. Place this in the
head of your page:

{% pusherable_subscribe 'update' object %}

The `pusherable_subscribe` tag will begin subscribe you to the channel for the
object. The first argument is the type of event you want to subscribe to.
The default events are `update` and `view`.

When a new event is received it will pass event type and data to a Javascript
function called `pusherable_notify`. Create this function and use it to alert your
users to the new event. For example:

function pusherable_notify(event, data) {
alert(data.user + "has begun to " + event + " " + data.model);

## Running Tests

Pusherable comes with test requirements and a test runner:

pip install -r requirements-test.txt

## Credits

django-pusherable was built by [Aaron Bassett]( for Pusher.
