pytkdocs/django compatibility issues

[jmcgill298]

Please open an issue on pytkdocs instead
if this is related to Python docstrings parsing or the collection of Python objects!

Describe the bug
Having pytkdocs >= 0.12.0 causes mkdocstrings build to crash with Django projects. Installation of pytkdocs with pip installs a version of pytkdocs >= 0.12.0.

To Reproduce
Steps to reproduce the behavior:

1. pip install mkdocstrings
2. add mkdocs config to load docstrings for Django project
3. run mkdocs build cli command
4. See error

Expected behavior
I expected the docs to be built

I am just a beginner

I am running the same version of pytkdocs and am not having an issue. I am no expert but I do want to try to help.

I had received a similar error or maybe even the same, I am not near my work station right now, but my issue was a bad mkdocs.yml. I had copied the config from somewhere online and produced and error. After checking the mkdocstring documentation, I removed a few lines I had in the handler config. If your handler does not look the same as mine below, that might be the issue.

plugins:
  - search
  - mkdocstrings:
      handlers:
        python:
          setup_commands:
            - import os
            - import sys
            - import django
            - sys.path.insert(0, os.path.abspath('../src/'))
            - os.environ.setdefault("DJANGO_SETTINGS_MODULE", "graphql_api.settings")
            - django.setup()

@jmcgill298 I hope that can be of some help.

I have the same AttributeError problem, but it's on my form.
AttributeError: 'ModelFormOptions' object has no attribute 'get_fields'
Did you manage to solve the problem?

A new Python handler is available and fixes all these AttributeError issues since it does not execute the code anymore, but only parses/visits it. Note however that this new handler is experimental and might not work as you expect, or as the legacy handler does, particularly with third-party libs like Django. Beta-tests and feedback are greatly appreciated! Closing for now, feel free to reopen, or open new issues.

Hi @BrayanMota,
I have exactly the same issue.
The new handler is still not supporting Django, so I'm stuck.
Did you find a solution to bypass those errors (for a class, a function or a whole module) and continue generating the documentation ?

[pawamoy]

If someone is willing to fix this, PRs are welcome in pytkdocs! I'm reopening this and moving the issue to pytkdocs' repo.
