Description

When generating python docs where the parameters are nested objects, their classes are not imported.

Example in the pet store docs:
https://github.com/OpenAPITools/openapi-generator/blob/master/samples/client/petstore/python/docs/PetApi.md#find_pets_by_tags

In this file, Tag should be imported.

openapi-generator version

latest master branch

OpenAPI declaration file content or url

In the Petstore example https://github.com/OpenAPITools/openapi-generator/blob/master/samples/yaml/pet.yml,
Pet has a $ref to Tag.

Nested imports were fixed in #13137

• in python-experimnetal v6.1.0 and later
• and in python in v6.2.0 and later

For the listed case, the Tag schema is defined inline in the endpoint, and it is generated as a Schema class in the endpoint module here: https://github.com/OpenAPITools/openapi-generator/blob/master/samples/openapi3/client/petstore/python/petstore_api/paths/pet_find_by_tags/get.py#L59

And the Pet model imports the Tag model here:

openapi-generator/samples/openapi3/client/petstore/python/petstore_api/model/pet.py

Line 215 in 085e1e5

from petstore_api.model.tag import Tag

I am still seeing this with python-nextgen 6.5.0 and 6.6.0-SNAPSHOT. Is this only fixed in python?

Yes. Python-nextgen did not exist when this ticket was created and closed. Please make a separate ticket for python-nextgen
