How do I use serializer_alias in OpenAPI schema?

[camuthig]

I am running into an issue trying to get my aliases working right for my use case.

I have a Django model with a field global_access on it

class MyModel(models.Model):
    global_access = models.BooleanField()

In my API, I need this field to be returned as the key global, which is a reserved keyword in Python. I am able to make this work, but I am not currently able to get it to both return as global AND be displayed as global in the generated OpenAPI schema. It seems like the primary issues is that for schema generation the validation_alias always supersedes the serialization_alias.

I am using by_alias=True on my router.

This configuration results in the API response being correct, but the schema being wrong. The schema shows this key as global_access rather than global

class MyResponse(Schema):
    global_access: bool = Field(
        ...,
        serialization_alias="global",
    )

If I put alias="global", then I must also set the validation_alias="global_access" or the API response fails. But as long as validation_alias is set, that is the key that appears in the schema. Does anyone know if there is a way, for response schemas, to leverage the serialization_alias instead of the validation_alias on the OpenAPI schema?
