Describe the bug
Currently, when we have a column of type "DATE", it is not properly serialized by the method "to_json" in the BaseMixin class.
Expected behavior
As currently done with datetime objects (or columns of type "TIMESTAMP"), the data should be string serialized (in isoformat or with a known date format).
