Hello,
Still working my way through James Bennett's Practical Django
Projects. Now on p. 64.
I get this import error when I try to syncdb the Coltrane models.
from tagging.models import Tag
File "/usr/lib/python2.5/site-packages/tagging/models.py", line 9,
in <module> from tagging.managers import TagManager,
TaggedItemManager
File "/usr/lib/python2.5/site-packages/tagging/managers.py", line 6,
in <module>
from django.db.models.query import QuerySet, parse_lookup
ImportError: cannot import name parse_lookup
Googling around I find this note:
While the public interface for the ORM-layer should stay the same, the
internals have undergone massive change. So if you're relying on some
private part of the API, you will have to check if it still works.
Affected of this if for example the popular django-tagging app (guess
what it does ;-)) which in its current state (r132) uses the no longer
available django.db.models.query.parse_lookup function. A patch by
Joes Watts is available here and seems to solve this issue. For more
details check out this ticket on django-tagging's google code project
page.
I've never patched code before. Can some kind soul please walk me
through the process step-by-step so I can continue on to page 65?
Many thanks,
Lloyd
