backbone.celery.js

A Backbone.js plugin for Celery. I am still working on this, it is not entirely useful yet. Ideas and suggestions are very welcome.

Create individual tasks and bind to their events:

var task = new CeleryTask({
    id: '785ba181-4c8b-4b35-a6c4-f47ad6b8d11a'
},
{
    interval: 5000,
    autoPoll: true
});
task.bind('task_SUCCESS', taskSucceeded);
task.bind('task_FAILED', taskFailed);

Or create task collections and deal with tasks as groups:

var tasks = new CeleryTasks();
tasks.add({id: '...'});
tasks.add({id: '...'});
tasks.pollAll();

This repo includes a demonstration Django project so the plugin has something to query. The demonstration task (which takes no args yet) will return 3 after sleeping for 5 seconds.

There is also a very simple Backbone.js app, which shows how the Model/Collection can be used, and how to automatically update a Backbone view to display the latest results from a task.

Getting started

Download the app, syncdb etc.

Start celerycam (so Task information is stored in the database):

./manage.py celerycam

Start celeryd (-E tells celeryd to send events, which are picked up by celerycam:

./manage.py celeryd -l info -E

Run the development server:

./manage.py runserver 127.0.0.1:8080

Open the test page in a browser:

http://127.0.0.1:8080/tasks/app/

Click 'New task' to create a new task which will be automatically polled.
