Can't build documentation after creating submodules

[fabifont]

Problem Description

I had a project with that structure:

buchino/
|-- init.py
|-- data.py
|-- controller.py
|-- documents/
|-- user.py
|-- place.py
|-- validation.py
|-- config.py
|-- bot.py
|-- scraper.py
|-- booker.py
|-- main.py

and I could build the documentation with: pdoc -d google *.py -o docs/
Then I decided to put some files into some folders and the last project structure is:

buchino/
|-- db/
|    |-- __init__.py
|    |-- init.py
|    |-- data.py
|    |-- controller.py
|    |-- user.py
|    |-- place.py
|-- utils/
|    |-- __init__.py
|    |-- validation.py
|    |-- config.py
|-- __init__.py
|-- bot.py
|-- scraper.py
|-- booker.py
|-- main.py

But now when I try to build the documentation with the same command I get that error:

Traceback (most recent call last):
  File "/usr/lib/python3.9/pathlib.py", line 736, in __str__
    return self._str
AttributeError: _str

During handling of the above exception, another exception occurred:

Steps to reproduce the behavior:

1. https://github.com/fabifont/buchino.git
2. cd buchino
3. git checkout dev
4. pdoc -d google *.py -o docs/

System Information

pdoc: 7.1.1
Python: 3.9.6
Platform: Linux-5.13.5-arch1-1-x86_64-with-glibc2.33

Thanks for the excellent repro steps! I'd generally recommend to use pdoc buchino over pdoc *.py, but we certainly should not crash.

I have just pushed a fix to main. Could you please update and verify that it works for you?

pip install -U https://github.com/mitmproxy/pdoc/archive/main.zip

Thanks for the reply. With your latest update now pdoc partially builds the documentation.
I get that error:

Project structure is the same. I tried both http (pdoc -d google buchino) and html (pdoc -d google buchino -o buchino/docs/) mode but they give the same error.

[mhils]

I think the core problem is really is that you have a __init__.py, which signals that your project is a module. However your imports do not match that: from db import controller as controller states that you want to import the module db, but if buchino is a module that should either be buchino.db or .db. So you should kind of make up your mind what you want to do here. :)

[fabifont]

There is always a problem:

• if I remove __init__.py it says module buchino not found
• if I add buchino. in front of imports it builds better but:
  • I can't execute anymore my program with python3 main.py: ModuleNotFoundError: No module named 'buchino'
  • pdoc can't build doc for bot.py:
