👋 Hi everyone! I'm having issues running pytest with alembic and pants. It seems the

alembic.ini

file is not being included in the pex runtime. I have attempted to explicitly include the ini file using the file and resource pattern. Still not managing to get this right. Any advice?

Could you provide the associated BUILD file?

Including the alembic.ini file explicitly sounds right, as dep inference won’t know about it. Whether it should be a

file

or a

resource

depends on how it’s loaded by alembic.

That's great advice! Let me give that a swing

@adamant-piano-24321 Did you ever work this one out?

I have indeed! The real trick is to utilise pants listing ability, i.e.:

./pants list ::

From this you can see which file with their appropriate path are available to the pants vm. To include a given file, navigate to the BUILD file in that source dir. You then have the option to either include a single or multiple files:

file(name="filename", source="filename.yml")

Run list to get the exact file pointer used by pants:

./pants list ::

Then where the file is needed:

python_tests(
    name="tests",
    dependencies=["path/path:filename"],
)

It was actually a different issue for me. Turned out that I needed the

prepend_sys_path

config option set in the

alembic.ini

to point to my python first party root for alembic to correctly find the models referenced in my env.py Seems to be something to do with their use of importlib to load modules when using alembic the cli tool
