Python 2.7 - erreur de serveur django 1.3 - Stack Overflow

I am using django version 1.3. Python manage.py runserver 0.0.0.0:8000 gives the following error.

Validating models...

Unhandled exception in thread started by < bound method Command.inner_run of < django.contrib.staticfiles.management.commands.runserver.Command object at 0x20eb110>>

Its working fine with django 1.4.2+, I was using django1.4 then upgraded it

pip install django==1.4.5 --upgrade

Django 1.3 had the issues of smart_bytes, and from your traceback it shows the same error, its been resolved in Django 1.4, Try upgrading Django to the latest version of 1.5.

See https://github.com/django/django/blob/master/django/utils/encoding.py#L149

Also, always check the release notes before upgrading your Django.

Update:

Sorry about that, wow, what a brainfart ;).

I don't know the full history of that function, but looking at django.utils.encoding on Github.. tagged 1.3.7; this file does not contain the function that Tastypie is attempting to import. https://github.com/django/django/blob/1.3.7/django/utils/encoding.py

If you cannot upgrade Django, you'll need to patch your Tastypie.utils.dict file to work with what you have.
