You cannot access the 'objects' attribute through an instance of a
class, you must do it through the class method.
In addition to what Matt said ('objects', not 'object'), this could
happen if you typed exactly what you had said if you had redefined
what 'List' refers to. Eg:
>>> Link.objects.get(id=1)
<Link: a link>
>>> Link = Link.objects.get(id=1)
>>> Link.objects.get(id=1)
Traceback (most recent call last):
File "<console>", line 1, in <module>
File "…/django/db/models/manager.py", line 219, in __get__
raise AttributeError("Manager isn't accessible via %s instances" %
type.__name__)
AttributeError: Manager isn't accessible via Link instances
If you are still having problems, copy and past your entire console
session so that we can see what you have done!
Cheers
Tom
