hi guys, a question, ammm, how is the correct way the use "aggregate sum",
what happens is that gives me a message a error
[image: Captura de pantalla 2018-09-14 a la(s) 10.39.42.png]
<about:invalid#zClosurez>
AttributeError: Got AttributeError when attempting to get a value for field
`fecha_ticket` on serializer `VentasSerializer`.
The serializer field might be named incorrectly and not match any attribute
or key on the `str` instance.
i don't know if this is the correct way.
thanks for read me
