在 Django Admin 中添加/编辑内联外键字段时出现问题

我有两个模型，School 和 UserProfiles，其中 UserProfiles 有一个指向 School 的外键。在 Django 管理中，我希望能够选择一所学校并让它显示所有具有外键的用户配置文件。

我这样做的方法是创建一个新的内联，模型是 UserProfile，并将其添加到新的 SchoolAdmin 并注册它。

当我去添加新的用户配置文件时，我的问题出现了。发生的情况是，我从下拉框中选择一个现有用户，然后单击“保存”。但是，我收到一条错误消息，指出“该用户的用户配置文件已存在”。

似乎在保存后，它会尝试为我选择的用户创建一个新的用户配置文件。我会以错误的方式这样做吗？

这是我设置的代码，用于在创建用户时自动创建用户配置文件。

def create_user_profile(sender, instance, created, **kwargs):
"""Create the UserProfile when a new User is saved"""
    print "User Profile Creation: False"
    if created:
        print "User Profile Creation: ", created
        UserProfile.objects.get_or_create(user=instance)



post_save.connect(create_user_profile, sender=User)

编辑：作为旁注，我如何才能跟踪程序流程以进行调试？我发现仅处理打印语句很困难。

原文

I have two models, School and UserProfiles, where UserProfiles has a ForeignKey to School. In the Django Admin, I want to be able to pick a school and have it display all the userprofiles that have a foreign key to it.

The way that I did this was to create a new Inline, with the model being the UserProfile, and adding it to the new SchoolAdmin and registering it.

My problem arises when I go to add a new userprofile. What happens is that I pick an existing user from the dropdown box and click save. However, I then get an error stating that a "User Profile with this User already exists."

It seems that upon saving, it tries to create a new User Profile for the user I pick. Am I going about doing this the wrong way?

Here is the code that I have set up to auto-create the user profiles when a user is created.

def create_user_profile(sender, instance, created, **kwargs):
"""Create the UserProfile when a new User is saved"""
    print "User Profile Creation: False"
    if created:
        print "User Profile Creation: ", created
        UserProfile.objects.get_or_create(user=instance)



post_save.connect(create_user_profile, sender=User)

EDIT: As a side-note, how can I go about tracing the program flow for debugging? I find it difficult to deal with just print statements.
