将Django模型导入python-cli脚本
原标题:Importing a Django model into a python cli script

我刚刚运行了这个django应用程序(也是一个经验不足的python用户),希望能够访问模型。

我有以下内容:

import sys, os
sys.path.append( /Users/jx/dev/arc/django/second/ )
os.environ[ DJANGO_SETTINGS_MODULE ] =  mysite.settings 
from django.db import models
from testproject.models import Location
loc=Location.objects.get(name= Joes )

print loc.name

但是得到以下错误:

Traceback (most recent call last):
  File "zz.py", line 6, in <module>
    from testproject.models import Location
ImportError: No module named testproject.models

有没有一种方法可以确定它是否正确加载了settings.py?或者是否存在明显的语法问题?PYTHONPATH是否应该反映模型的位置(如果打印os.environment,则目前没有)?

thx

  1. Make sure you have added the folder containing testproject folder to sys.path. For example if you have the following structure /foo/bar/testproject/models.py then you should add /foo/bar to sys.path
  2. Make sure the testproject folder has a __init__.py file in it (which can be empty).

Django支持创建自定义Django管理命令(文档)。

对于创建访问模型的命令行脚本非常有用。

如果它没有正确加载您的设置,那么从django.db导入模型的将失败。事实上,您的测试项目包找不到;将包含testproject/的目录添加到sys.path。
