Validation is only intended from external data (basic Python types) to more
complex structures (Django models). This happens during deserialization.
Here, you are already providing a complex model like it was basic Python types.
In order to work this around, it should be:
data = {
‘owner_id’: 1,
‘code’: ‘foo’
}
ser = SnippetSerializer(data=snippet, many=False)
ser.is_valid(raise_exception=True)
