Django Rest Framework notes

１．DjangoFilterBackend，精确搜索

from django_filters.rest_framework import DjangoFilterBackend

filter_backends = (DjangoFilterBackend,)
filter_fields = ("username",) 这里的tupl是个坑，一定要多个

对应URL:http://localhost:8000/hostaccount/v1/userkey?username=guoguo1

The relationship between the database table:
category and source is a one-to-many relationship
