mkPoetryApplication should create bins for the scripts

Found it in a Github issue. And it was efficient at the time I tested it to remove the bin error.
For what I can remember.

Without this part, I get the following error :

I removed it and sill get the error about test.default missing.

EDIT truh :
I removed it and sill get the error about test.default missing.

I just set it at the minimum level :

          testApp = mkPoetryApplication {
            projectDir = ./.;
            overrides = p2n-overrides;

            dependencies = [
              pkgs.redis
              pkgs.ffmpeg
            ];

          };

With the package inside the pyproject.toml, I have this error :

Not sure why it is not working in my test package. But in the original package specifying the packages inside the pyproject.tom worked well.

I have now errors complaining about Flask not present.
Do you know why the packages/libraries from the pyproject.toml are not present during run time ?

Anyway thank you for your attention and idea to fix my issue.

I have some thing like

        devShells.a = pkgs.mkShell {
          packages = with pkgs; [
            (mkPoetryEnv {
              projectDir = a/.;
              python=pkgs.python39;
            })
          ];
        };

        devShells.b = pkgs.mkShell {
          packages = with pkgs; [
            (mkPoetryEnv {
              projectDir = b/.;
              python=pkgs.python39;
            })
          ];
        };

I'm trying to set up a python enviroment with poetry2nix. I need to override a package rpds-py to make it function correctly. It already has a override at line 3082 to 3147 in overrides/default.nix But that doesn't have the hash to the latest version. How do I force it to use the correct hash for the latest release?
I know it's a simple override, but everything I try fails to set the hash to what it should be.

I'm trying the following:

{rpds-py = prev.rpds-py.overridePythonAttrs (old: {
          cargoDeps = nixpkgs.rustPlatform.fetchCargoTarball {
            inherit (old) src;
            name = "${old.pname}-${old.version}";
            hash = "sha256-qIXdoCEVGCGUnTicZp4bUTJyGpFy9dwWY03lXUbxiHg=";
          };
          buildInputs = old.buildInputs or [ ] ;
          nativeBuildInputs = old.nativeBuildInputs or [ ] ++ [
            nixpkgs.rustPlatform.cargoSetupHook
            nixpkgs.rustPlatform.maturinBuildHook
          ];
        });
      }

Hey! I'm wondering how to correctly set up a devShell using poetry2nix. Previously, I was using:

      devShells.default = pkgs.mkShell {
        packages = with pkgs; [ poetry ];
        LD_LIBRARY_PATH = "${pkgs.stdenv.cc.cc.lib}/lib/";
      };

together with

PYTHON_VERSION=$(python --version | awk '{print $2}' | cut -d. -f1-2 | tr -d '\n')
export PYTHONPATH=$PYTHONPATH:$(poetry env info --path)/lib/python${PYTHON_VERSION}/site-packages

in my .envrc, but I was hoping to get the same effect more gracefully using mkPoetryEnv, so I tried:

      devShells.default = mkPoetryEnv {
        projectDir = ./.;
      };

but for some reason the dependencies aren't available:

» grep pandas pyproject.toml
pandas = "2.1.3"

» python -c "import pandas"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ModuleNotFoundError: No module named 'pandas'

Any idea what I'm doing wrong?

Hey! Whats going on with ipympl?
I've encountered a problem with the ipympl library.

First I added ipympl as a dependency:

poetry add ipympl
Using version ^0.9.4 for ipympl

Then, when I tried to enter the development environment with the command nix develop I received the following message:

nix develop
warning: Git tree '/home/user/test-jupyter' is dirty
error: builder for '/nix/store/yn9990741wv439qncd2wpl2pdbwkjzyz-python3.12-ipympl-0.9.4.drv' failed with exit code 2;

       >   File "<frozen importlib._bootstrap>", line 1324, in _find_and_load_unlocked
       > ModuleNotFoundError: No module named 'hatchling'

I tried to override ipympl:

myapp = mkPoetryApplication {
    projectDir = self;
    overrides = withDefaults (final: prev: {
        ipympl = prev.ipympl.overridePythonAttrs (old: {
            nativeBuildInputs = old.nativeBuildInputs or [ ] ++ [ final.hatchling ];
        });
    });
};

But it was unsuccessful:
