Python will be able to import db_testing.views just fine even if you
don't import viewsi from . in db_testing/__init__.py. All Python cares
about is that there is a correct Python file in the correct location.

If you're interested in more details about what's going wrong here,
there's an explanation here:
https://docs.djangoproject.com/en/1.10/ref/applications/#how-applications-are-loaded

In particular, the following paragraphs:

What's happening here is that the root of your "db_testing" package
(i.e. db_testing/__init__.py) indirectly imports models, because it
imports the views module, which in turn imports models.

Just removing the "from . import views" line should let you move
forward – unless you also have other imports in the __init__.py file,
in which case you can most likely just remove them, too. In general,
in an average Django package, there's little reason to import stuff in
its root package.

Good luck,

Michal
