python-pydantic-v1: Return the primitive type in to_dict for anyOf models

[chiragjn]

Python pydantic definitions for models with multiple schemas using anyOf implement to_dict incorrectly when one of the types is not a pydantic BaseModel.
The function should just return the type as is instead of json dumping it

I don't know if this is considered a breaking change

PR checklist

• Read the contribution guidelines.
• Pull Request title clearly describes the work in the pull request and Pull Request description provides details about how to validate the work. Missing information here may result in delayed response from the community.
• Run the following to build the project and update samples:

  ./mvnw clean package 
  ./bin/generate-samples.sh ./bin/configs/*.yaml
  ./bin/utils/export_docs_generators.sh
  

  (For Windows users, please run the script in Git BASH)
  Commit all changed files.
  This is important, as CI jobs will verify all generator outputs of your HEAD commit as it would merge with master.
  These must match the expectations made by your contribution.
  You may regenerate an individual generator by passing the relevant config(s) as an argument to the script, for example ./bin/generate-samples.sh bin/configs/java*.
  IMPORTANT: Do NOT purge/delete any folders/files (e.g. tests) when regenerating the samples as manually written tests may be removed.
• File the PR against the correct branch: master (upcoming 7.6.0 minor release - breaking changes with fallbacks), 8.0.x (breaking changes without fallbacks)
• If your PR is targeting a particular programming language, @mention the technical committee members, so they are more likely to review the pull request.

@multani Would appreciate a review on this.

Currently this serialization bug is preventing me from using the pydantic v1 generator.

[multani]

@chiragjn Could you provide a test to exercise this code and prevent further regressions in the future?

[chiragjn]

@multani Sorry, I am bit lost, should I be editing

https://github.com/OpenAPITools/openapi-generator/blob/master/modules/openapi-generator/src/test/java/org/openapitools/codegen/python/PythonPydanticV1ClientCodegenTest.java ?

[multani]

This file (or the whole folder actually) contains hand-written tests for such a case: https://github.com/OpenAPITools/openapi-generator/blob/master/samples/openapi3/client/petstore/python-pydantic-v1/tests/test_model.py (there's a similar folder for the asyncio generator)

It would be great it you could extend this test suite to show how the issue is fixed by this change. Thanks!

[chiragjn]

Before this change, this would render as '"#123456"'

which is incorrect for to_dict

[chiragjn]

@multani Updated test, hope this helps

[multani]

Looks good to me, @wing328 can you check?

[multani]

Thanks for the added tests @chiragjn !

[chiragjn]

Sorry for being annoying, Bumping this again to @wing328
Hoping this can land so I can start using this generator soon

[wing328]

@chiragjn just merged the PR. Thanks again for your contributions.
