如何在DRF中将电子邮件字段设置为lookup_field？

# models.py
from django.db import models

class User(models.Model):
    email = models.EmailField(unique=True)
    # 其他字段...

# serializers.py
from rest_framework import serializers
from .models import User

class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = User
        fields = '__all__'

# views.py
from rest_framework import viewsets
from .models import User
from .serializers import UserSerializer

class UserViewSet(viewsets.ModelViewSet):
    queryset = User.objects.all()
    serializer_class = UserSerializer
    lookup_field = 'email'  # 设置lookup_field为'email'

# urls.py
from django.urls import path, include
from rest_framework.routers import DefaultRouter
from .views import UserViewSet

router = DefaultRouter()
router.register(r'users', UserViewSet)

urlpatterns = [
    path('', include(router.urls)),
]
