[BUG]: Nested objects not decoded with to_dict() or to_json()

[bmmcwhirt]

Is there an existing issue for this?

• I have searched the existing issues

Description of the bug

When using the to_dict() or to_json() of the DataClassJSONMixin object you get a bound method error unless you are at the very bottom level.

Each class that is inheriting DataClassJSONMixin needs to implement to_dict() and to_json() and decode the subsequent classes. This needs to be done for every object type that contains other objects of type DataClassJSONMixin so that the bottom level all the way to the top can be serialized.

Currently what happens is you are returning a dict or json that contains a SnyKClient object.

Steps To Reproduce

import json

from snyk import SnykClient
from snyk.models import Organization, Project

from utils import get_default_token_path, get_token


def get_client() -> SnykClient:
    snyk_token_path = get_default_token_path()
    snyk_token = get_token(snyk_token_path)
    client = SnykClient(token=snyk_token)
    return client


def demo_bug(snyk_client: SnykClient, org_id: str, project_id: str):
    organization: Organization = snyk_client.organizations.get(org_id)
    project: Project = organization.projects.get(project_id)
    with open(file='organization_output.json',
              mode='w', encoding='utf-8') as file:
        file.write(json.dumps(organization.to_dict(), indent=4))
        file.close()
    with open(file='project_output.json', mode='w', encoding='utf-8') as file:
        file.write(json.dumps(project.to_json(), indent=4))
        file.close()


def run(function):
    function(snyk_client=get_client(),
             org_id='',
             project_id='')


if __name__ == '__main__':
    run(demo_bug)
