After some hacking about with the rather badly documented Python FUSE bindings, I have finally managed to mount a CouchDB document's attachments directly onto a virtual filesystem!

Use Cases

• If you've read My Couch or Yours? Shareable Apps Are The Future by jchris, this is a great time-saver if you want to edit HTML, JavaScript, CSS or even image files directly using your favourite editor.
• Uploading large numbers of files repetitively through Futon or even via a Python prompt becomes tedious very quickly: drag'n'drop or cp * is the way forward!

Installation

You need the following:

1. Python FUSE bindings
2. CouchDB-Python 0.5 or greater
3. CouchDB-FUSE

Running python setup.py install should install a couchmount script on your path.

Usage

$ mkdir mnt
$ couchmount http://localhost:5984/jasondavies/_design%2Flinks mnt/
$ ls mnt/
$ touch mnt/foo
$ ls mnt/
foo
$ 

...you get the idea...

Happy Couching!

Finally, Django 1.0 is released!

After countless hours of hard work by many talented people, it is a pleasure to see the long-awaited version 1.0 released to the world. Finally, a version number that reflects the quality of the codebase, which in fact I have been using in production for many months.

New features that I am excited about include:

Re-factored admin application

Developed under the newforms-admin branch for a long while, the re-factored admin application is much more customisable and means I don't have to do so many ugly hacks and workarounds any more. See the admin reference for details.

Re-factored ORM

The internals of the ORM were pretty much rewritten from scratch in the queryset-refactor branch, resulting in many annoying bugs being fixed. This also includes support for model inheritance, which allows for more elegant models. See the wiki for more details.

Have fun!

Lets you see your Python program's execution as a tree of function invocations, each tree node exposing the real time, and CPU time (user/sys) of that call.

This looks pretty cool, I will have to try this out on some of my Django projects.

I have long been a fan of list comprehensions in Python, but it's only recently that I discovered a related piece of sugary syntax: generator expressions.

Now, instead of something like:

sum([item.price for item in self.item_set.all()])

I do:

sum(item.price for item in self.item_set.all())

Just that little bit cleaner and more efficient...
