An import should be generated I think that this used to work

EDIT: moved to https://github.com/OpenAPITools/openapi-json-schema-generator/issues/3 as my original comment is in fact a separate, unrelated issue and I don't want to cause confusion to anyone else reading this.

@mikeknep can you make a separate issue for that? The property that you mention is a codegenProperty whereas the one that I am mentioning is a codegenModel so they work differently. Hmm this may be because Animal sees Age as an AnyTypeSchema but a Dog instance is a DynamicSchema instance but it should be let through because Age is a DictSchema. Why are you AllOf including Animal in Dog and Cat? Doing that is not adding any useful validation.

FYi if you want to use this it is working in the v2.0.0 release of openapi-json-schema-generator. That is where further development is being done on the python generator. Here is the definition of the component schema RefPet

    RefPet:
      $ref: '#/components/schemas/Pet'

And here is the generated class

from petstore_api.components.schema import pet
RefPet = pet.Pet
