我是Django的初学者，所以无法弄清楚问题是什么。我试图寻找类似问题的解决方案，但无法解决问题。我遇到了属性错误，然后在AssetSerializer中输入many=True后解决了这个问题，但现在我遇到了这个KeyError。在试图找出错误时，我注意到这个错误是在执行serializer.data时抛出的。感谢您的帮助。
在您的代码中，只需要对语法进行一个小的更改。
而不是：
user = Asset.objects.filter(devUserId=devUserId).values()
写入：
user = Asset.objects.filter(devUserId=devUserId)
这应该能解决问题！
尝试
user = Asset.objects.values('fieldnamehere').filter(devUserId=devUserId)
