Python 不同的结果后序列化取决于环境

我从rest web json表单和custom_answers字段发送请求，其中包含转换后的列表数据，但当我使用ApiClient从测试发送相同的数据时，custom_answers null list

从restf web json表单打印已验证的_数据创建序列化程序方法

{'custom_answers': [OrderedDict([('user', <SimpleLazyObject: <User: 123>>), ('question', <Question: Вопрос 2>), ('text', 'TExt')]), OrderedDict([('user', <SimpleLazyObject: <User: 123>>), ('question', <Question: Вопрос 1>), ('text', 'tes')])], 'poll': <Poll: Опрос 1>, 'user': <SimpleLazyObject: <User: 123>>}

您发送的数据的默认内容类型是不支持嵌套数据的html表单

您需要明确指出您正在发送json数据：

{custom_answers': [{'text': 'TExt', 'question': 2}, {'text': 'tes', 'question': 1}], 'poll': 1}

response = self.client.post(reverse('api_v1:complete-poll'), data, format='json')
