JSON Encoding & Decoding ======================== By default Quart-Schema extends the DefaultJSONProvider to use the pydantic encoder if the value cannot be encoded. This can be altered by overriding this change after initialising the Quart-Schema extension i.e. .. code-block:: python QuartSchema(app) app.json_encoder = MyJSONEncoder # To override This is best as the pydantic decoder must be used (to create pydantic models) and hence this ensures consistency.
