# 或者: from rest_framework.serializers import py [as 别名]
def get_fields(self):
""" Return the field_mapping needed for serializing the data."""
# Re-implement the logic from the superclass methods, but make sure to handle field and query facets properly.

# 或者: from rest_framework.serializers import py [as 别名]

# 需要导入模块: from rest_framework import serializers [as 别名]
# 或者: from rest_framework.serializers import py [as 别名]
def get_distinct_count(self, instance):

# The instance is expected to be formatted as a three tuple containing the field name, normal count and
# distinct count. This is consistent with the superclass implementation here:
