This is actually part 3 of our django-mediagenerator Python canvas app series (see part 1 and part 2), but since it has nothing to do with client-side Python we name it differently. In this part you'll see how to make your web app load without an Internet connection. HTML5 supports ...

In part 1 of this series we've seen how to use Python/pyjs with django-mediagenerator. In this part we'll build a ridiculously simple HTML5 canvas drawing app in Python which can run on the iPad, iPhone, and a desktop browser.

Why ridiculously simple? There are a few details ...

This is the first part in a short series (see also part 2 and part 3) on building a simple client-side offline-capable HTML5 canvas drawing app in Python via Pyjamas/pyjs, using django-mediagenerator. Canvas drawing apps are the "Hello world" of the web apps world, so why not make it ...

This is a quick update: Rob Vaterlaus has started working on a Cassandra backend and Alberto Paro is working on an ElasticSearch backend for Django-nonrel.

The Cassandra backend is still experimental and lacks support for ListField (from djangotoolbox.fields), but overall it already looks very very interesting. This backend comes ...

In part 1 and part 2 we introduced the concept of denormalization, materialized views and background tasks in order to emulate JOINs in the to-one direction on NoSQL databases. Now we'll talk about all remaining little but important snippets of the puzzle left over and discuss how to ensure ...

In part 1 we discussed a workaround for JOINs on non-relational databases using denormalization in cases for which the denormalized properties of the to-one side don't change. In this post we'll show one way to handle JOINs for mutable properties of the to-one side i.e. properties of ...

Non-relational databases like App Engine or MongoDB natively don't support operations like JOINs because they don't scale. However in some situations there just exists the need to use such operations. This is the first part of a series presenting one way to handle JOINs (at first in the ...

With the just released django-dbindexer you can use all Django lookup types ("iexact", "month", "day", etc.) on non-relational DBs like App Engine and MongoDB, even if they're not natively supported by that DB! Also, django-dbindexer can help you with optimizing your code. For instance, case-insensitive filters on MongoDB can ...
