Snippet List

RestfulView

In the same vein as [snippet 436](http://www.djangosnippets.org/snippets/436/), this allows you to differentiate view logic by HTTP method such as GET, POST, PUT, DELETE. This is also very useful combined with the [HttpMethodsMiddleware snippet](http://www.djangosnippets.org/snippets/174/). I am not the author, but I have found it to be very helpful.

backupdb command

`backupdb` command allows to make a database backup automatically. It's supposed to do this just before a `syncdb`, `reset` or `flush` command in a server deployment. A usual upgrade task in production server could be: ./manage.py backupdb ./manage.py reset myapp ./manage.py syncdb Put this code in your project's `management/commands/backupdb.py` file.

Call resize_image to replace the image with a resized and normalized version of itself. I recommend doing this with celery, but you could also hook it up to the admin interface if you're not impatient.

Django profiler

The script that can be used to profile any Django-powered web-site and find how many SQL-queries are used per page, how heavy html-pages are, etc. To use the the script it's enough to put django-profile.py somewhere in PYTHONPATH and call it from the directory that holds projects' settings.py.
