ModuleNotFoundError: No module named 'drf_multiple_model'

Answer 1

Django Rest Framework提供了一些令人难以置信的用于序列化数据的工具，但是有时您需要将许多序列化器和/或模型组合到单个API调用中。 drf-multiple-model是一款专为此目的设计的应用。

（from the documentation）

好吧，我想您找到了答案，但是如果其他人也遇到了同样的问题，也许就是这样：

pip install django-rest-multiple-models

请确保将drf_multiple_model添加到您的INSTALLED_APPS中，然后将视图导入任何views.py中。
