1 个解决方案

#1

The transaction middleware was deprecated in Django 1.6, and removed in Django 1.8. Remove the following line from your middleware classes.

事务中间件在Django 1.6中已弃用，在Django 1.8中被删除。从中间件类中删除以下行。

'django.middleware.transaction.TransactionMiddleware',

There is a new feature ATOMIC_REQUESTS which you can use instead.

ATOMIC_REQUESTS有一个新功能，您可以使用它。

For more information, have a look at the section of the docs which explains the changes to transactions.

有关更多信息，请查看解释事务更改的文档部分。
