Please tell us more about your question or problem

Hey!

I'm wondering whether it's possible to track a specific branch of our internal Python dependency using Poetry manager in Renovate.

Context

We have a following repository_core dependency defined in pyproject.toml

[tool.poetry.dependencies]
python = "3.13.0"
repository_core = { git = "https://gitlab.com/my-company/my-team/repository-core", rev = "12345commithash"}

and in a Dockerfile

FROM gcr.io/my-company-gcr/repository-core:12345commithash
...

Problem

I found a way to track the default (dev) branch of repository-core and update the commit hash in both places. But I can't seem to find a way to update the commit hash from a specific branch (other than default dev).

It's possible to use the regex manager for that (already implemented in the config for Dockerfile) but in Poetry I can't find a way to do it. Is tracking a specific branch of git-refs supported by Poetry manager?

Alternatively, if it's not possible - is it possible to run poetry lock after updates using per-project config (not global)? I am able to replace commit hashes in both places using regex manager but it leaves us with broken poetry.lock file.
