I swapped hy = { git = "https://github.com/hylang/hy.git", python = ">=3.9,<3.11" } for hy = {version = "1.0a4", allow-prereleases = true, python = ">=3.9,<3.11"}, did a poetry update and now mkPoetryEnv returns Hy 1.04a, which is the latest pre-release. It would be nice to get the tip of the master branch but this works fine for my purposes now

i'm trying to build a package that depends on cryptography 36.0.2, and it fails with:

error: hash mismatch in fixed-output derivation '/nix/store/cb7576730h5ny4x6177dcxy3gl2qvfvl-cryptography-36.0.2-vendor.tar.gz.drv':
         specified: sha256-kozYXkqt1Wpqyo9GYCwN08J+zV92ZWFJY/f+rulxmeQ=
            got:    sha256-6C4N445h4Xf2nCc9rJWpSZaNPilR9GfgbmKvNlSIFqg=

this is because the hash is hard-coded here, and it's now wrong.

what's the idea here? how do we keep that hash updated? should i just override on my end?

Is there a way to use the environment of a derivation to add more files to it right before the Python package is created? I’m creating a derivation for a Django project, and I’d like to collect static files to a directory that’s inside my package. I’m currently doing this by using mkPoetryApplication to create the package, and then have a second mkPoetryApplication with ${appWithoutStatic}/bin/django-admin collectstatic in configurePhase. This works but I was wondering if this is achievable without creating 2 derivations.

i'm newbie with nix, but as far as i can understand, proper way to achieve desired, is to make override with custom build paramaters. poetry2nix uses nixpkgs.buildPythonPackage. So i believe there are plenty of post* hooks, which you can use to add aditional step to your build. You only need to figure out proper way to override resulting derivation.

are you replying to me? sorry can't see what you're replying to

could poetry2nix automatically detect and handle this edge case?
