Question

我正在开发一些项目，该项目从rest API读取数据，然后反序列化数据以存储到数据库中。下面是模型和反序列化器

class ExchangeInfo(models.Model):
    server_time = models.BigIntegerField()
    timezone = models.CharField(max_length=20)

class ExchangeInfoSerializer(serializers.ModelSerializer):
    server_time = serializers.IntegerField(source='serverTime')
    timezone = serializers.CharField(max_length=20)


    class Meta:
        model = ExchangeInfo
        fields = '__all__'

以下是我用于反序列化数据的代码

def load_exchange_info():
    exchange_info = client.get_exchange_info()
    from common.models import ExchangeInfo
    from common.serializers import ExchangeInfoSerializer
    exchange_info_serializer = ExchangeInfoSerializer(data=exchange_info)
    exchange_info_serializer.is_valid()
    print(exchange_info_serializer.errors)

is_valid总是如何返回False，错误如下。

{'server_time': ['This field is required.']}

关于这个问题的任何建议？

修改：

正确的序列化程序是：

class ExchangeInfoSerializer(serializers.ModelSerializer):
    serverTime = serializers.IntegerField(source='server_time')
    timezone = serializers.CharField(max_length=20)

    class Meta:
        model = ExchangeInfo
        fields = ('serverTime', 'timezone')

当使用source属性声明自定义字段时，django rest框架modelserializer is_valid返回false
