The error traceback you've posted doesn't seem to have anything to do with the actual code - it seems to be some sort of problem with middleware (presumably when rendering the 500 error page).

您发布的错误回溯似乎与实际代码没有任何关系 - 它似乎是中间件的某种问题（大概是在渲染500错误页面时）。

However, your error is probably caused by your use of the undefined variable name attach in the calls to mail.attach. You don't have an attach variable - you've called the posted files image1 etc, so you should use those names.

但是，您的错误可能是由于在对mail.attach的调用中使用未定义的变量名附加引起的。你没有附加变量 - 你已经调用了发布的文件image1等，所以你应该使用这些名称。

mail.attach(image1.name, image1.read(), image1.content_type)
mail.attach(image2.name, image2.read(), image2.content_type)
mail.attach(image3.name, image3.read(), image3.content_type)
