这两个都在“生产”中工作，后者只在测试中工作。现在我已经在生产和测试中得到了一些工作，我想了解为什么我必须走整个游标路线而不是 Django 路线。我相信问题与交易有关，但我并不积极，因为我晚上 8:30 坐在这里，这让我很烦。
这与这个问题有关，我认为我有我的答案（和理解），但可惜我没有。我的测试是一个 A/B，其中 A 在 Django 外部注入，B 与已知的 A 进行比较。提供的答案解决了我的部分问题，但是当我添加更多测试时，问题不断浮出水面。
我深入研究并假设它是 RawQuery 没有提交交易，但没有金额transaction.commit似乎可以解决它。我还从中删除了django.testing.TestCase它并直接进行了单元测试。我想我已经尝试了每一种组合，但我对 SQL 或事务支持不是很精通，现在我想知道为什么一个有效而一个无效......
如果有人在这里有任何见解，我将不胜感激！
