geoDjango - ImportError：無法導入名稱SpatialBackend

Question

我試圖做一個應用程序與geoDjango但我實際上有一些問題，使其運行。 當我excecute的 「蟒蛇manage.py執行syncdb」 命令，我有以下錯誤：

File "/media/datos/Proyectos/CualBondi/git/cualbondi/myapp/models.py", line 10, in <module> 
from django.contrib.gis.db import models 
File "/usr/local/lib/python2.6/dist-packages/django/contrib/gis/db/models/__init__.py", line 5, in <module> 
from django.contrib.gis.db.models.aggregates import * 
File "/usr/local/lib/python2.6/dist-packages/django/contrib/gis/db/models/aggregates.py", line 2, in <module> 
from django.contrib.gis.db.models.sql import GeomField 
File "/usr/local/lib/python2.6/dist-packages/django/contrib/gis/db/models/sql/__init__.py", line 2, in <module> 
from django.contrib.gis.db.models.sql.query import GeoQuery 
File "/usr/local/lib/python2.6/dist-packages/django/contrib/gis/db/models/sql/query.py", line 4, in <module> 
from django.contrib.gis.db.models.fields import GeometryField 
File "/usr/local/lib/python2.6/dist-packages/django/contrib/gis/db/models/fields/__init__.py", line 3, in <module> 
from django.contrib.gis.db.backend import SpatialBackend, gqn 
ImportError: cannot import name SpatialBackend 

我這裏給您一些額外的信息：

• 的Django 1.3.1
• Python 2.6
• Ubuntu 10.04
• PostgreSQL 8.4.8

你有什麼想法嗎？ 非常感謝！

也許這有幫助，SpatialBackend似乎不推薦使用。閱讀下面的警告。

All functionality of `SpatialBackend` has been moved to the `ops` attribute of the spatial database backend.

我在django 1.3.0，似乎工作良好，但只有警告。
