Django elasticsearch DSL DRF建议问题 [英] Django elasticsearch DSL DRF suggetions issue

问题描述

我正在我的项目中实现Django elasticsearch DSL DRF，以创建用于Elasticsearch的其余API.弹性搜索工作正常，但搜索建议中存在问题.根据文档，如果我在URL中使用建议，那么它将显示错误屏幕.但是我没有添加，然后我得到了错误的答复.我正在附上我的代码的屏幕截图.

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.

推荐答案

您应该继承自 DocumentViewSet ，而不是 BaseDocumentViewSet .

You should inherit from DocumentViewSet instead of BaseDocumentViewSet.
