Steps to reproduce
- Create the above
api.yaml.
- Create the above
config.yaml.
- Create an empty
templates directory.
- Run the above
generate command.
Expected result
Should create a gen/openapi_client/model/test.pyi file according to templates/model-stub.mustache.
Related issues/PRs
Suggest a fix
It would appear that the use of templateType: model is causing the generator to add __init__model.mustache to the file list multiple times. There does not appear to be a way to prevent this.
As I am not redefining or providing a template for __init__model.mustache, it should not be trying to add it again.
