Django loaddata settings error

When trying to use loaddata on my local machine (win/sqlite):

python django-admin.py loaddata dumpdata.json

I get the following error:

raise ImportError("Settings cannot be imported, because environment variable %s is undefined." % ENVIRONMENT_VARIABLE) ImportError: Settings cannot be imported, because environment variable DJANGO_SETTINGS_MODULE is undefined.

I am using djangoconfig app if that helps:

"""
Django-config settings loader.
"""

import os

CONFIG_IDENTIFIER = os.getenv("CONFIG_IDENTIFIER")
if CONFIG_IDENTIFIER is None:
    CONFIG_IDENTIFIER = 'local'

# Import defaults
from config.base import *

# Import overrides
overrides = __import__(
    "config." + CONFIG_IDENTIFIER,
    globals(),
    locals(),
    ["config"]
)

for attribute in dir(overrides):
    if attribute.isupper():
        globals()[attribute] = getatt开发者_开发百科r(overrides, attribute)

Don't use django-admin.py for anything other than setting up an initial project. Once you have a project, use manage.py instead - it sets up the reference to your settings file.

---

syncdb will load content_types, you need to clear that table before loading data. Something like this:

c:\> sqlite3 classifier.db
sqlite> delete from django_content_type;
sqlite> ^Z
c:\> python django-admin.py loaddata dumpdata.json

Also, make sure you do not create a superuser, or any user, when you syncdb, as those are likely to also collide with your data fixture ...

There are two standard ways to provide your settings to Django.

• Using set (or export on Unix) set DJANGO_SETTINGS_MODULE=mysite.settings
• Alternatively as an option with django-admin.py --settings=mysite.settings

Django-config does things differently because it allows you to have multiple settings files. Django-config works with manage.py to specify which to use. You should use manage.py whenever possible; it sets up the environment. In your case try this where --settings points to the specific .py file you want to use from django-config's config folder.

django-admin.py loaddata dumpdata.json --settings=<config/settings.py>

Actually --settings wants python package syntax so maybe <mysite>.config.<your settings>.py
