[Answered ]-Using a database in a Django view

In Django you access database via models.

First you configure your database access and credentials in settings.py:

https://docs.djangoproject.com/en/dev/ref/settings/#databases

Then you can perform queries against your models:

https://docs.djangoproject.com/en/dev/topics/db/queries/

E.g.

User.objects.get(username=request.POST["username"])

Then there is a special case for safe user authentication for which Django has its own procedure:
