django-excel, pyexcel, save_to_database ['function' 对象没有属性 '_meta']
django-excel, pyexcel, save_to_database ['function' object has no attribute '_meta']
我想将 excel 数据传输到数据库（postgres 数据库）。
作为pyexcel的引导线，我使用函数save_to_database
但它不起作用，我不知道哪里出了问题..请帮助我
我收到这个错误：
内部服务器错误：/weekly_upload

我不知道django-excel或save_to_database方法，但很明显model=weekly_upload这里是不正确的。 weekly_upload 是您的视图函数，但您可能打算使用的模型 class 称为 Weekly_upload（大写字母 W）。
尝试在此处更改最后一行：
from .models import Weekly_upload
...
def weekly_upload(request):
...
request.FILES['file'].save_to_database(model=weekly_upload, ...)
至：
request.FILES['file'].save_to_database(model=Weekly_upload, ...)
此外，我建议为 classes 采用 python pep8 约定命名约定：WeeklyUpload.
这样可以更容易地避免这种错误。也许尝试为模型或视图函数找到一个不同的、更具描述性的名称，这样您就不会将它们相互混淆。
