Introduction

I have created a web-app python project with the following structure (source files omitted from tree command for clarity)

$ tree -I *__pycache__* -L 2 -P *.py my_project/

my_project/
├── __init__.py
├── backend
│   ├── __init__.py
│   ├── clients.py
│   ├── config.py
│   ├── fetchers.py
│   ├── filters.py
│   ├── logger.py
│   ├── matchers.py
│   ├── plotters.py
│   ├── types.py
│   └── utils.py
└── frontend
    ├── __init__.py
    ├── assets
    ├── callbacks.py
    ├── components.py
    ├── config.py
    ├── ids.py
    ├── layout.py
    ├── main.py
    └── maindash.py

The contents of the __init__.py files are the following:

$ cat my_project/__init__.py

from .backend import (
    CDFConfig,
    client_credentials,
    client_interactive,
    TransmitterTypeFilter,
    CDFFetcher,
    RollingCorrelationMatcher,
    EmptyTimeseriesFilter,
    utils,
    Logger,
    PlotFactory,
)

from .frontend import (
    ids,
    callbacks,
    config,
    layout,
    maindash,
    main,
    components,
)

__all__ = [
    "CDFConfig",
    "CDFFetcher",
    "client_credentials",
    "client_interactive",
    "TransmitterTypeFilter",

    "ids",
    "callbacks",
    "config",
    "layout",
    "maindash",
    "main",
    "components",
]

$ cat my_project/backend/__init__.py

from .config import CDFConfig
from .clients import client_credentials, client_interactive
from .filters import TransmitterTypeFilter, EmptyTimeseriesFilter
from .fetchers import CDFFetcher
from .matchers import RollingCorrelationMatcher
from .utils import get_reference_fetcher
from .logger import Logger
from .plotters import PlotFactory

__all__ = [
    "client_credentials",
    "client_interactive",
    "CDFConfig",
    "CDFFetcher",
    "TransmitterTypeFilter",
    "RollingCorrelationMatcher",
    "EmptyTimeseriesFilter",
    "get_reference_fetcher",
    "Logger",
    "PlotFactory",
]

$ cat my_project/frontend/__init__.py

from . import ids
from . import callbacks
from . import config
from . import layout
from . import maindash
from . import main
from . import components

__all__ = [
    "ids",
    "callbacks",
    "config",
    "layout",
    "maindash",
    "main",
    "components",
]

Problem

I am building my documentation with sphinx, using the following rst file for the API documentation:

==========
My Project
==========

Backend
=======
.. automodule:: my_project.backend
    :members:
    :undoc-members:
    :show-inheritance:
    :private-members:
    :special-members: __init__


Frontend
========
.. automodule:: my_project.frontend
    :members:
    :undoc-members:
    :show-inheritance:
    :private-members:
    :special-members: __init__

The backend is documented as expected, but only the header is shown for the frontend. Why is that? I think it has to do with the init files and the way I import functionality into the namespace, but I cannot figure what is wrong.
