如何从第三方模块访问Django设置？

Question

i'm writing a django-agnostic module, that will be importet anywhere inside django subdir tree.

I want that if this module is imported from within any arbitrary django project, it will detect that it's running in a django environment, and it will find and import settings.py, from anywhere inside the project?

eg \\django \\app \\import XXX.settings ?

\\django \\project \\somewhere \\import XXX.settings

(I'm, looking for a general purpose solution, not in particular to a specific dir.)

Answer 1

Your module should access django settings in the standard way:

from django.conf import settings

from https://docs.djangoproject.com/en/1.8/topics/settings/#using-settings-in-python-code

Also note that your code should not import from either global_settings or your own settings file. django.conf.settings abstracts the concepts of default settings and site-specific settings; it presents a single interface. It also decouples the code that uses settings from the location of your settings.

If your module has it's own settings, they can be configured in the project's settings.py. You can hard-code sensible defaults in your module, and you can raise ImproperlyConfigured if you require a settings.py value.
