序列化器嵌套的使用

from .models import Nav
class SonNavModelSerializer(serializers.ModelSerializer):
      """嵌套的子序列化器"""
     class Meta:
         model = Nav
         fields = ["name", "icon", "link", "is_http"]

class NavModelSerializer(serializers.ModelSerializer):
    """导航序列化器"""
    # 序列化器嵌套使用,必须是外键字段才可以使用序列化器嵌套
    son = SonNavModelSerializer(many=True)# 当前序列化器SonNavModelSerializer为多时,使用many=True
    class Meta:
        model = Nav
        fields = ["name","icon","link","is_http","son"]
