First time poster, so let me know if I need to provide more info! I have a Django project of the following structure:
a/b/c/d/
├── e
│ ├── BUILD.pants
│ ├── myapp
│ │ ├── BUILD.pants
│ │ ├── migrations
│ │ ├── models.py
│ │ ├── ...
│ │ └── tests
│ ├── BUILD.pants
│ ├── settings.py
│ ├── ...
│ └── wsgi.py
├── BUILD.pants
├── ...
└── manage.py
The Django app can be run using manage.py runserver perfectly fine, but it uses relative and app-level imports which causes Pants and Pyright issues within my repo. I want to set it up on Pants anyways, so I have switched all my relative imports to absolute imports (which breaks it running via Django directly).
This is my BUILD.pants at a/b/c/d:
python_sources()
pex_binary(
name="manage",
entry_point="manage.py",
dependencies=["a/b/c/d/e"],
restartable=True,
)
Running manage.py through Pants, instead of starting the app, produces the following:
./pants run a/b/c/d:manage -- runserver --noreload

ModuleNotFoundError: No module named 'd'
In manage.py main() it looks like the offending line is:
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'b.c.d.e.settings').
(In my repo all absolute imports are relative to b, even though the file is located in directory a/b). Trying to change this line to some other import path will unsurprisingly give the same error, just with a different module not being found.
I've tried:
This example repo structure is a bit different because it uses a service architecture, but I tried to mimic the patterns I could pick out. --noreload also doesn't do anything for me.
This post I've used to try and structure my build files, but I don't think this is the same core issue, since running ./pants dependencies shows the correct dependencies for my directories.
I think the issue is something silly, where I'm not using the correct directory structure/import structure in one of the build/settings files, but I've tried all the combinations I can think of and nothing seems to work. I'm a total noob with Pants so I'm not sure how to setup the pex_binary() and python_sources() in the BUILD.pants files.
