Re: Python question about positioning of "from... import" statement

Hi!

If i'm not wrong, the reason is that you try to import rango.models before django.setup()

Try moving django.setup() after you import django and then your

from rango.models import Category, Page

Though i'm not sure it will work either, because you call:

os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'tango.settings')

after from rango.models import...

Let me know if that helped :)

Hi, this is more of a Python question but here is something I don't understand in a Django script.

The following script works fine:

import os

import django

if __name__ == '__main__':

    print("Starting Rango delete data script...")

    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'tango.settings')

    django.setup()

    from rango.models import Category, Page

    Page.objects.all().delete()

    Category.objects.all().delete()

    print("Deleted all data from tables: Page and Category.")

...but when I move the "from... import" statement to the top of the file:

import os

import django

from rango.models import Category, Page

if __name__ == '__main__':

    print("Starting Rango delete data script...")

    os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'tango.settings')

    django.setup()

    Page.objects.all().delete()

    Category.objects.all().delete()

    print("Deleted all data from tables: Page and Category.")

...I get an error:

  File "C:\landy\lib\site-packages\django\conf\__init__.py", line 40, in _setup

    % (desc, ENVIRONMENT_VARIABLE))

django.core.exceptions.ImproperlyConfigured: Requested setting DEFAULT_INDEX_TAB

LESPACE, but settings are not configured. You must either define the environment

 variable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing s

ettings.

What is going on?

Thanks
