QuerySet API reference (stock portfolio example)

An in-depth guide to Django QuerySet (Django 3.0, updated June 2020).

When QuerySets are evaluated

Internally, a QuerySet can be constructed, filtered, sliced, and generally passed around without actually hitting the database. No database activity actually occurs until you do something to evaluate the queryset. Examples of that "something" that cause a QuerySet to evaluate:

1. Iteration: QuerySet executes its database query the first time you iterate over it

   for q in Quote.objects.all():
       print(q.symbol)

Demystifying Docker Volumes for Mac and PC Users

1. Docker runs on a Linux kernel

Docker can be confusing to PC and Windows users because many tutorials on that topic assume you're using a Linux machine.

As a Linux user, you learn that Volumes are stored in a part of the host filesystem managed by Docker, and that is /var/lib/docker/volumes. When you're running Docker on a Windows or Mac OS machine, you will read the same documentation and instructions but feel frustrated as that path don't exist on your system. This simple note is my answer to that.

When you use Docker on a Windows PC, you're typically doing one of these two things:

• Run Linux containers in a full Linux VM (what Docker typically does today)
