SQLAlchemy 的类导入问题

    我本来是吧所有类放到一个models.py文件下，每个类继承相同的Base,这样在建表的时候直接import models模块
    现在我想把类分开放到不同的文件里，但都放到models包里，但是这样我在from models import * 时就是不能创建表，只能from models import user 这样才行，又没有什么好的方法直接导入全部呢？

  • models
  • import
  • 导入

    你的 __init__.py 里设置 __all__ 了吗？

    @coolrice 你需要设置这个字典，详见 https://docs.python.org/3/tutorial/modules.html#importing-from-a-package

    @billlee 貌似懂了，不过要自己手动写好，有没有方法能得到这个包下的所有模块名字？

    @coolrice find models/ -maxdepth 1 -name *.py -print0 | xargs -0 basename -s .py
