returns the error that Django cannot find the model.

有什么主意吗?谢谢！

它应该起作用，请确保在__init__.py中从first_model.py和second_model.py导入所有模型.

It should work, make sure that in __init__.py you are importing all the models from first_model.py and second_model.py.

from .first_model import FirstModel
from .second_model import SecondModel

如果要以'app_label.model_name'检索模型，则必须将它们导入__init__.py，否则可以尝试以下操作:

If you want to retrieve the models as 'app_label.model_name', then you will have to import them in __init__.py, otherwise you can try the following:
