Я закодировал сериализатор и представления, которые должны обновлять экземпляры объекта модели. Когда я тестирую API с помощью Django Rest Browsable API, процесс работает нормально, но не при использовании curl. запросы curl (GET, PATCH и PUT) показывают 302 на сервере, и ничего не обновляется, когда метод является patch:
команда curl равна:
curl -X PATCH -H "Content-Type: application/json" -d '{ "status": "undefined", "started_at": "2022-03-31T08:22:54"}' http://localhost:8000/wf/machineworks/b79ac69b-e9a6-410b-bfbd-a79b0163f69a
, а для команды curl команда сервер выдает:
[31/Mar/2020 12:50:33] "PATCH /wf/machineworks/b79ac69b-e9a6-410b-bfbd-a79b0163f69a HTTP/1.1" 302 0
, тогда как то же самое обновление в API для просмотра дает:
[31/Mar/2020 13:20:25] "PATCH /fr/wf/machineworks/b79ac69b-e9a6-410b-bfbd-a79b0163f69a/ HTTP/1.1" 200 12588

Я видел много проблем, близких к этому, но я не нашел ответа, который работает ... кажется простым, но я совсем растерялся ...
