Manage two pyproject.toml and local dependency

[mihalikv]

I have the following structure of the project(with old requirements.txt managed by hand and installed by pipy):
core_package -> standalone project, with separate git and own requirements.txt(most of the packages)
project_specific_package -> project that needs core_package to live, and have own requirements.txt i.e.

-r core_package/requirements.txt
mssql==1.0.1

I can add requirements.txt to core_package and project_specific_package when developing these things.
The project structure is:

project_specific_package/
     .git
     requirements.txt
     pyproject.toml - in the future with Rye
     core_package/
         .git
         requirements.txt
         pyproject.toml - in the future with Rye

Is it possible somehow create just one virtualenv in root of project_specific_package? and when I run rye sync inside core_package/ it will generate core_package/requirements.lock just from core_package/pyproject.toml

I tried to use following pyproject.toml:

[project]
name = "project_specific_package"
version = "0.1.0"
description = "Add a short description here"
authors = [
    { name = "", email = "" }
]
dependencies = [
    "core_package @ file:///home/user/project_specific_package/core_package",
]
readme = "README.md"
requires-python = ">= 3.8"

[build-system]
requires = ["setuptools>=61.0"]
build-backend = "setuptools.build_meta"

[tool.rye]
managed = true

And when I run rye sync it works like expected it will generate requirements.lock with all dependencies from core_package and it will install it to virtualenv. What if I want to add package to core_package ? If I navigate to core_package and run rye add it just won't work.

One more experience with pip-tools, that I also tried and I am in beginning of using it. I am managing dependencies only in core_package and when I want to generate core dependencies I simply run
pip-compile --resolver=backtracking --upgrade -o sbcore/requirements.txt sbcore/pyproject.toml. Is it maybe some option to define source of pyproject.toml with some switch ?

Thanks.

So my new observation is, that I can use

[tool.rye.workspace]
members=["core_package"]

to have only one virtualenv as I need.

But I still have problem to add package to core_package/pyproject.toml with rye add

What's the error when you try to add a dependency? Sounds like a bug should be filed if you can provide the info
