Serializer

验证

class OrderSerializer(serializers.Serializer):
    order = serializers.IntegerField()
    node = serializers.CharField()

    @staticmethod
    def validate_order(value):
        try:
            order = Order.objects.get(id=value)
            if order:
                return order
            else:
                raise serializers.ValidationError("工单不可", code=403)
        except WebOrder.DoesNotExist:
            raise serializers.ValidationError("工单不存在", code=404)

    @staticmethod
    def validate_node(value):
        if re.match("^\d{8}$", value):
            node_user = User.objects.get(id=value)
        if node:
            return node
        raise serializers.ValidationError("参数有误", code=403)

serializer = OrderSerializer(data=request.GET)
if not serializer.is_valid():
    return_msg = "\n".join([i + ": " + '\t'.join(serializer.errors[i])
                            for i in serializer.errors.keys()])
    return JsonResponse({"status": 400, "data": {}, "msg": return_msg})
data = serializer.validated_data

递归字段

from rest_framework import serializers
from rest_framework_recursive.fields import RecursiveField

class TreeSerializer(serializers.Serializer):
    name = serializers.CharField()
    children = serializers.ListField(child=RecursiveField())
