policyportal2020.PolicyPortalUser.user_ptr ：（字段E305）“ PolicyPortalUser.user_ptr”的反向查询名称与“ PolicyPortalUser.user_ptr”的反向查询名称发生冲突。提示：在“ PolicyPortalUser.user_ptr”或“ PolicyPortalUser.user_ptr”的定义中添加或更改related_name参数。
**同时运行这两个应用程序policyportal和policyportal2020相互冲突，我尝试过，简而言之，我想在Django应用程序中复制粘贴应用程序，但使用不同的名称和相同的功能。 **

您可以像这样更改PolicyPortalUser类，这将解决您的问题
class PolicyPortalUser(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE, related_name ='PolicyPortal2020User_user')
...other fields...
class PolicyPortalUser(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE, related_name ='PolicyPortalUser_user')
