Inherited properties from external parent classes not showing in subclass docs

[ndonkoHenri]

Hey there, and thanks for the awesome package.

I’m documenting a Python package using mkdocs-material along with the mkdocstrings Python handler.
I have a class that inherits from an external item, for example, pandas.DataFrame, and I will like the parent props to be visible in the child's docs.

I tried a bunch of stuffs (preload_module: [pandas], inherit_members: true), but nothing worked as expected.

Can anyone help me out, please?

Could you provide a minimal example that reproduce the issue you describe (no inherited members rendered)? What you tried is supposed to be the solution (preload_modules: [pandas], inherited_members: true). Note that it's preload_modules (plural) and inherited_members (not inherit_members).

Thanks for the quick response!

In my particular case, I have a class named DataColumn2 inheriting from flet.DataColumn, but as you can see on my deployed docs, only the children props are shown.

• mkdocs.yml with preload_modules: [flet] and inherited_members: true
• flet.DataColumn code
• proof of flet in venv

Also, locally I tried copying the source code of the flet.DataColumn into my package and inheriting from it instead, and it worked (props were seen in docs).

Let me please know if you need additional info.

Try running mkdocs serve -v, you'll see a lot of DEBUG messages like the following:

Skip /run/media/pawamoy/Data/dev/tmp/flet-datatable2/.venv/lib/python3.13/site-packages/flet/controls/material/text_button.py, it is not importable. Missing init module?

If you fix them by adding the relevant __init__ modules in flet sources, I believe Griffe will be able to load the data correctly.

Worked, thanks!
