How to install django-utils?

Question

I tried installing django-utils from source code from github and using pip. The installation goes fine however the queue_command does not work within my django app.

So as suggested in the docs, I tried running `python setup.py test' and I get the following error. I have not idea how to fix this. I am running from within virtualenv on mac snow leopard.

Any suggestions? Thank you.

Try using django.db.backends.sqlite3 instead.

Answer 1

What version of Django are you running? 1.3 deprecated the old-style way of specifying databases, for example, using just 'sqlite3'. You now must specify the entire import path, i.e. django.db.backends.sqlite3.

However, I was pretty sure that 1.3 still let you use the old-style way and simply fussed at you, warning that it's deprecated. Perhaps I was wrong though. If you're running off trunk, then, it's almost certainly fully deprecated, which makes that error a little more understandable.

The long and short is that since the last update of django-utils was back in 2009, it's effectively dead, and Django has moved on.

Answer 2

1. Open your settings.py
2. Replace 'ENGINE': 'sqlite3', with 'ENGINE': 'django.db.backends.sqlite3',
3. Save

Try again.
