如何过滤Django序列化数据？

from django.core import serializers
from myapp.models import User

users = User.objects.all().exclude(email='')
data = serializers.serialize('json', users, fields=('name',))

from django.core import serializers
from myapp.models import User

users = User.objects.all().values('name')
data = serializers.serialize('json', users)

from django.core import serializers
from myapp.models import User

users = User.objects.all().values_list('name', flat=True)
data = serializers.serialize('json', users)

from rest_framework import serializers
from myapp.models import User

class UserSerializer(serializers.Serializer):
    name = serializers.CharField()

    def to_representation(self, instance):
        data = super().to_representation(instance)
        return {key: value for key, value in data.items() if key == 'name'}

users = User.objects.all()
serializer = UserSerializer(users, many=True)
data = serializer.data
