django-cors-headers VS psycopg2

django-cors-headers, a Django app to add CORS headers to the application.

Django does not include tools to handle CORS configuration from the core package. To make this work, you'll need to reach for a third party package. Since CORS configuration is handled through HTTP headers, you'll find that the very appropriately named django-cors-headers package is exactly what you need.

This might not be of any help at all since i dont use bottle, but in django its common to use django-cors-headers.

For more information about django-cors-headers, check this document.

This is a solution I found when looking at the source code of the well known package Django Corsheaders. It is very, very simple. Just define a wrapper over the django.conf.settings, and specify a property per each setting that your library allows to customize.

I'm only guessing, check if you have the middleware in the list as high as possible.

And set the headers as per your requirement using the Documentation

You can practice both by using https://www.psycopg.org from your Python code to communicate with your database. When I wanted to practice some SQL, that's what I did (we use psycopg at work, so that's what I practiced with, making a dream journal thingy for myself that was better than just noting stuff in a notepad because I could then look up e.g. what other stuff was correlated with Y, how many times I dreamed of X, etc. etc.)

But seems like it should work with Django 3, which you have specified https://github.com/psycopg/psycopg2/issues/1293

If you're using Postgres for your SQL, look at the "copy' method of the psycopg module (see https://www.psycopg.org/articles/2020/11/15/psycopg3-copy/) . It's much faster than INSERTs in my experience (YMMV).

Back when I used Psycopg2, there was no -binary package, so you'd get libpq set up similarly to pg-native. Docs say:

> The binary package is a practical choice for development and testing but in production it is advised to use the package built from sources.

I dunno, this seems worse to me.

Just go to the more easily readable docs here. I’m sorry, but the linked article is terrible.

psycopg2-binary. See https://github.com/psycopg/psycopg2/issues/1286.

psycopg2-binary, PostgreSQL Database adapter for python.

... # psycopg2==2.9.3 # https://github.com/psycopg/psycopg2 ...

I sometimes do this in testing. For example, consider the library used to communicate with a Postgres database, psycopg.
