json_schema_extra at the class level

[JoanPuig]

Is there a feature that would allow the generated code to keep the extra fields in the OpenAPI schema at the class level?

Example OpenAPI fragment:

info:
  title: Example API
  version: '1.0'
openapi: 3.0.0
components:
  schemas:
    MyType:
      x-type-metadata:
        type-metadata-1: type md 1 value
        type-metadata-2: type md 2 value
      type: object
      properties:
        myProperty:
          type: string
          x-field-metadata:
            field-metadata-1: field md 1 value
            field-metadata-2: field md 2 value

Expected generated code:

class MyType(BaseModel):
   json_schema_extra={ # <-- is it possible to have this generated?
        "type-metadata": {
            "type-metadata-1": "type md 1 value",
            "type-metadata-2": "type md 2 value",
        }
    },
    myProperty: Optional[str] = Field(
        None,
        json_schema_extra={
            "field-metadata": {
                "field-metadata-1": "field md 1 value",
                "field-metadata-2": "field md 2 value",
            }
        },
    )

I tried to look for it https://github.com/koxudaxi/datamodel-code-generator/issues?q=json_schema_extra+ but I could only find field level extra fields.

Any help would be appreciated.

Thanks,
Joan
