Скачать или смотреть Django ORM - Querying and Creating Records / Working with Foreign Keys

In this video, we'll cover ways to query databases with the Django ORM, and ways to create data with the ORM.

We'll look at a number of techniques, including the following methods:
Model.objects.all()
Model.objects.filter() / Model.objects.exclude()
Model.objects.first() / Model.objects.last()
Model.objects.create() / Model.objects.get_or_create()

We'll also look at how to create and query Foreign Key relations in Django.
