我正在为我的应用程序编写测试。我在互联网上搜索了相同的错误，但找不到任何东西。我昨天有这个错误，但是最后期限很紧。今天，我面临着同样的错误。似乎仅当我尝试将用户onetoone字段两次分配给两个不同的模型时，才会出现此错误。发生的事情是我正在尝试创建两个不同的配置文件。一个配置文件是卖方配置文件，另一个是买方配置文件。测试代码->

在添加以下测试之前，一切正常。
# Test editing seller profile

# Initialize data
user = User.objects.get(pk=1)
with open('test_data/profile2.jpg', 'rb') as dp:

这是我执行测试时收到的错误消息->
