I'm trying to get editablePackageSources to work such that I can run pytest in a flake devshell and it will test my package, but be sensitive to local edits. Can I get some help?

I put together a repo for this request: https://github.com/MatrixManAtYrService/pytest_poetry2nix

pytest typically runs against the source code, so you shouldn't need to do anything special to achieve this. It's only if you want to run tests against the compiled application that you'd need to re-run nix develop to test against changed files.

Oh that makes sense. So instead of figuring out how to get an editable install via poetry2nix, I should be trying to figure out why the import (test module importing app) is failing for whatever other reason.

This is what I needed to hear l0b0 , thanks for the hint.

When I set editablePackageSources.myapp = ./src, this should work right? So that when I edit ./src/myapp/test.py, I thought I should be able to see that change when I run python -m myapp.test, but the same code is executed for me.

Update: I've created a PR with the relevant failing test.

Anyone experienced "missing attribute" error recently? Wrt. `inputs.flake-utils.lib.eachDefaultSystem`. Once I made it follow my existing `flake-utils` input I get nix complaining about line 82 in poetry2nix's `flake.nix` on current `master` (`5a62572`).

Here's my flake.nix, stripped of non-Nix/poetry2nix related sturr:

{
  description = "A Nix-flake for poetry based python development ";

  inputs = {
    flake-utils.url = "github:numtide/flake-utils";
    nixpkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable";
    poetry2nix = {
      url = "github:nix-community/poetry2nix";
      inputs.nixpkgs.follows = "nixpkgs";
      inputs.flake-utils.follows = "nixpkgs";
    };
  };

  outputs = {
    self,
    ...
  } @ inputs:
    inputs.flake-utils.lib.eachDefaultSystem (system: let
      pkgs = import inputs.nixpkgs {localSystem = {inherit system;};};
      inherit (inputs.poetry2nix.lib.mkPoetry2Nix { inherit pkgs; }) mkPoetryApplication;
      myapp = mkPoetryApplication {projectDir = self;};
    in {
      devShells.default = pkgs.mkShell {
        inputsFrom = [myapp];
        packages = with pkgs; [
          poetry
          (
            python3.withPackages (
              exts: [
                exts.ipython
              ]
            )
          )
        ];

        shellHook = ''
          ${pkgs.python3}/bin/python3 --version
          ${pkgs.poetry}/bin/poetry --version
        '';
      };
      packages = {
        inherit myapp;
      };
      packages.default = myapp;
    });
}

You could try nixpkgs.follows = "poetry2nix/nixpkgs"; rather than the other way around.

Thanks for taking a look @truh! Huhm...
I agree that there's a channel mismatch between the two...

But how do you figure it's related to the error message? I don't see anywhere there might be a reference to a flake-utils version missing https://github.com/numtide/flake-utils?tab=readme-ov-file#eachdefaultsystem--system---attrs.

  `inputs.flake-utils.follows = "nixpkgs";` this shouldn't follow nixpkgs
