Thank you for the report. 

I'll try to reproduced it this week. Meanwhile a full stacktrace would be helpful.

[idlesign]

Unable to reproduce it with a simple app and quickstart sample (http://django-siteprefs.readthedocs.io/en/latest/quickstart.html). Works as expected.

Do you encounter this exception on start? How do you structure your code?

[toxa23]

Yes, the exception appears at the very beginning. Please take a look at my settings.py and trace log. I do not deny, maybe this is me doing something wrong. sources.zip

Some hints:

1. The basic idea with Django is to use apps. So you need to create settings.py in your app (just as in quickstart) and define settings there.
2. Boolean value is handled automatically, no need to define field.
3. To deal with env vars you can use https://github.com/idlesign/envbox or something similar instead of get_env_variable.

Considered closed. Feel free to reopen if required.

I encountered this also, when I try to described preferences in my project/settings.py

Traceback (most recent call last):
  File "/path_to_root/project_wide/settings.py", line 788, in <module>

    app_config = apps.get_containing_app_config(module)

@toxa23 's solution works for me https://github.com/BanzaiTokyo/askapp/blob/f1a5aba/siteprefs/toolbox.py#L24 . I'll submit a patch shortly.
