Unresolved reference in Django's docstring in PyCharm
PyCharm does not appear to have support for this currently. The active issue for this in JetBrains issue tracker is https://youtrack.jetbrains.com/issue/PY-16760, please consider upvoting it to get it fixed. The only workaround if you want to avoid seeing these "Unresolved reference" errors in your docstrings is to disable the inspection in Preferences > Editor > Inspections > Unresolved references.
Another option that I have tried in the past is removing the "Attributes:" header and writing my attribute documentation on the same indentation level as the rest of the docstring. This no longer gives you a warning, but you are no longer conforming 100% to the Google Docstring Style Guide.
I solved this issue by adding a '# noqa' after the 'Attributes:', because i did not want to disable the unresolved reference warning.
So this would be the final docstring:
"""
Class for posts.
Attributes: # noqa
title(str): Post title.
"""
