pretalx

[fricklerhandwerk]

Pretalx is one of the leading open source tools capable of handling the full organisation of events from Call for Proposals to user feedback, and is used by many large open source events already (MozFest, FOSDEM, Pycon, NSEC, etc).

• NLnet project
• pretalx.com
• source code
  • schedule component
• prior work:
  • pretalx configuration for NixCon

Since this project supports "components", it will need a configurable setup. Break down into separate issues as needed.

The goal here is to provide turnkey setup for self-hosting.

@ngi-nix/algae will look into this, starting 2023-07-31.

@ngi-nix/algae is progressing, packaging pretalx via poetry2nix. At the moment, it runs in a basic configuration (webserver started via shell, using an SQLite database). We'd like to introduce services soon and at that point #28 would be helpful. We haven't yet looked into a solution for components.

A note regarding "optional dependencies": As of now, we have:

• psycopg2-binar for PostgreSQL
• mysqlclient for MySQL
• django-redis for Redis
• Faker and freezegun for (integration) testing

See also:

ngipkgs/pkgs/pretalx/pyproject.toml

Lines 12 to 16 in 4d5af8f

	psycopg2-binary = "*"
	Faker = "*"
	freezegun = "*"
	mysqlclient = "*"
	django-redis = "*"

It looks like the preferred way to specify such dependencies is Poetry extras. However, according to nix-community/poetry2nix#400 there's no good support for exposing extras via poetry2nix.

NixOS/nixpkgs#231684 exists and is probably further along.

[lorenzleutgeb]

Cool, especially that you managed to package it without poetry2nix! We've merged our work in the meantime. Overall, the approach is quite similar, as would be expected. There are some differences though (handling secrets, using pretalx create_test_event). It might be worth it for you to check out our contribution.

The PR to nixpkgs is awaiting further review with our contributions but in the meantime it seems we're done here
