Description

Description

Currently, swagger-codegen only recognizes that last inline object defined in an allOf: array. The OpenAPI Specification is silent on this issue and leaves it to the tools to decide.

https://github.com/OAI/OpenAPI-Specification/issues/848

I am writing this issue so that this issue can be defined in swagger-codegen.

Swagger-codegen version

2.2.2-SNAPSHOT

Swagger declaration file content or url

See issue # 4226 for example.

Suggest a Fix

Specify a constraint that only one inline object can be created within a model definition.
OR
Handle it properly. If this option is chosen, how are discriminators dealt with in the inline objects? What other issues will come up when this is addressed?

IIUC, 2.2.3 addresses inheritance, interfaces and composition in a more complete way, right? So maybe for 2.2.2, the constraint is the best option.

Research direction

Review issue #4226 for the referenced example, then read the OpenAPI Specification discussion in issue #848 and the swagger-codegen 2.2.2 composition behavior. The work would need a decided policy for multiple inline objects in allOf, including how discriminators are handled, or an explicit constraint limiting them.
