我发送的发帖请求。

django不读取字段，如响应所示： “名称”： [ “这是必填栏。” ]， “ drone_category”：[ “这是必填栏。” ]， “生产日期”： [ “这是必填栏。” ]

您需要更改此

class UserDroneSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
         model = Drone
         fields = (
            'url',
            'name',
        'drone_category',
        'manufacturing_date',
        'has_it_competed',
        'inserted_timestamp',
        'owner')

发送此字段后，仍然出现“此字段为必填”错误
