flask_restx fields.Raw 不允许 None

Question

I just switched from flaks_restplus to flask_restx. I start getting the marshal error.

jsonschema.exceptions.ValidationError: None is not of type 'object'

I defined this field in my modal, and the dict I passed in.

"my_field": fields.Raw

{... 'my_field': None}

How can I allow None for the field?

Answer 1

I guess I found the answer. The field I defined is wrapped in field.Nested()

I have to pass in the optional parameter field.Nested(myModel, skip_none=True)

It is not intuitive...
