Research direction

Start in openapi_python_client/parser/properties/init.py around line 463 and reproduce the failure with openapi-python-client generate --url https://sand-docs.ilevelsolutions.eu/openapi.yaml. Trace how list-valued enum defaults are represented and check the relevant parser tests. Done means the specification generates successfully without the TypeError and existing behavior remains intact.

Description

🐞bug

Describe the bug
When generating models for an API where a default argument is a list of enums, a TypeError is raised on this line:

return f"{prop.class_info.name}.{inverse_values[default]}"

A possible fix could be to explicitly check for this case. Below is a proposed fix, but I'm not familiar enough with the codebase to know whether this is a correct fix. However, I was able to parse the API docs correctly with this fix in place:

if type(default) is list:
    return [f"prop.class_info.name.inverse_values[d]" for d in default]
else:
    return f"{prop.class_info.name}.{inverse_values[default]}"

To Reproduce
Steps to reproduce the behavior:

  1. Run openapi-python-client generate --url https://sand-docs.ilevelsolutions.eu/openapi.yaml
  2. See error

Expected behavior
The API docs should be able to be parsed
