Django elasticsearch DSL DRF suggetions issue

问题

I am implementing Django elasticsearch DSL DRF in my project to create rest API for elasticsearch. Elastic search is working fine but having the issue in search suggestions. As per documentation if I use the suggest in URL then it gives error screen. But I don't add that then I got an incorrect response. I am attaching screenshots of my code.

Code for View

        'field': 'id',
        # Note, that we limit the lookups of id field in this example,

回答1:

You should inherit from DocumentViewSet instead of BaseDocumentViewSet.
