PostgreSQL DATE, TIMESTAMP, and INTERVAL cheat sheet

Working with DATE, TIMESTAMP, and INTERVAL in PostgreSQL can be confusing. In this article I will go over the three date/time related data types, and the two most useful date/time functions: DATE_PART and DATE_TRUNC. Finally, I will provide some real life examples of how these types and functions can be used within queries.

Types

PostgreSQL Date/Time Documentation

DATE

The DATE type contains the year, month, and day of a date. It is not possible to do any type of time related functions on a DATE without first converting it to a TIMESTAMP. Subtracting two DATE values from one another results in an INT representing the # of days between.

TIMESTAMP

The TIMESTAMP type contains a year, month, day, hour, minute, second, and microsecond. This is the type that I most often use.

Why?

I got sick of writing the same Serializer & ModelViewSet classes over and over so I found and wrote some code to do it for me, and somehow it works! Please note that there are a lot of caveats to running an API like this and while this may work, I know there's A LOT of room for improvement, feel free to fork and help!

USAGE

Import the router module to your main sites urls.py file as the injection point like so... Make sure to remove any other imports from other viewsets that you don't need that may conflict!

Docker migrate to overlay2 from aufs script

Crazy that this is pretty much forced change without proper transition script

note. Based on https://www.sylvaincoudeville.fr/2019/12/docker-migrer-le-stockage-aufs-vers-overlay2/ NOT WORKING!!!! IF FOLLOWING THE ABOVE.. SOMEHOW THE CONTAINERS DO NOT RE-APPEAR!

The only way I found that is somewhat automated is the the docker-compose way..

Which is still not 100% and require manual fixing of stupid errors of the docker-compose tool (mainly things that ere not interpreted right, like dates & userIds that need to manually surrounded by quotes etc)
