我正在使用Pycharm 4开始一个新的Django项目。我已经定义了各种模型,如果我运行测试,比如这个,
from django.test import TestCase
from models import OwnerDatabase
class TestZero(TestCase):
def test_Settings(self):
item=OwnerDatabase.objects.first
一切正常。但是在项目的不同部分,如果我有这个代码(一个独立的脚本)
from models import OwnerDatabase
该程序有以下追溯
File "/home/piffy/PycharmProjects/Russeau/russeau/datasetcreate.py", line 9, in <module>
from russeau.models import OwnerDatabase, PublishedDatabase
File "/home/piffy/PycharmProjects/Russeau/russeau/models.py", line 4, in <module>
class OwnerDatabase(models.Model):
File "/home/piffy/PycharmProjects/Russeau/russeau/models.py", line 5, in OwnerDatabase
time = models.DateTimeField()
File "/usr/local/lib/python2.7/dist-packages/django/db/models/fields/__init__.py", line 1098, in __init__
super(DateField, self).__init__(verbose_name, name, **kwargs)
File "/usr/local/lib/python2.7/dist-packages/django/db/models/fields/__init__.py", line 146, in __init__
self.db_tablespace = db_tablespace or settings.DEFAULT_INDEX_TABLESPACE
File "/usr/local/lib/python2.7/dist-packages/django/conf/__init__.py", line 46, in __getattr__
self._setup(name)
File "/usr/local/lib/python2.7/dist-packages/django/conf/__init__.py", line 40, in _setup
% (desc, ENVIRONMENT_VARIABLE))
django.core.exceptions.ImproperlyConfigured: Requested setting DEFAULT_INDEX_TABLESPACE, but settings are not configured. You must either define the environment variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.
但是,在manage.py中,我已经有了
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "Russeau.settings")
虽然我对Django和Python比较陌生,但我的其他项目并没有这样的问题。关于如何继续,我也不知所措。
谢谢!
---更新:
感谢下面的Daniel,我添加了
import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "Russeau.settings")
所以错误现在改为
django.core.exceptions.AppRegistryNotReady: Models aren't loaded yet.
在良好的轨道上,但是......?
答案 0 :(得分:2)
如果是独立脚本,则需要先设置Django设置。在这种情况下,manage.py
与它无关,因为您没有使用它来调用您的脚本。要解决此问题,您有两种选择:
将此内容写在脚本的顶部:
sys.path.append("/path/to/project") #Set it to the root of your project
os.environ["DJANGO_SETTINGS_MODULE"] = "<project>.settings"
django.setup()
之后,您应该可以从项目中导入模型或任何需要的模型。如果需要,您可以查看this以获取更详细的说明。
创建custom management command,以便您可以致电python manage.py mycommand
。
