Django reg extend current事务被中止，命令被忽略，直到事务b结束

Question

我试图根据以下内容扩展django-registration寄存器表单：

Python/Django django-registration add an extra field

但我得到了：

current transaction is aborted, commands ignored until end of transaction block

在调试过程中，我在建议的regbackend.py中添加了一个断点，这表明损坏的代码位于：

from crewcal.models import UserProfile
from forms import *

def user_created(sender, user, request, **kwargs):
    form = CustomRegistrationForm(request.POST)
    data = UserProfile(user=user)
    import ipdb; ipdb.set_trace();
    data.locality = form.data["locality"]
    data.save()

from registration.signals import user_registered
user_registered.connect(user_created)

问题（如下）可能与我的models.py中定义的创建用户配置文件的方式有关：

^{pr2}$

在上面列出的regbackend.py断点产生的shell中，我可以生成：

    > /Users/project/app/regbackend.py(8)user_created()
      7     import ipdb; ipdb.set_trace();
----> 8     data.locality = form.data["locality"]
      9     data.save()

ipdb> data
<UserProfile: gub>
ipdb> vars(data)
{'user_id': 81, 'locality': None, '_user_cache': <User: gub>, '_state': <django.db.models.base.ModelState object at 0x103eb6990>, 'receive_email': True, 'id': None}
ipdb> form.data['locality']
u'BERLIN'
ipdb> data.locality = form.data['locality']
ipdb> vars(data)
{'user_id': 81, 'locality': u'BERLIN', '_user_cache': <User: gub>, '_state': <django.db.models.base.ModelState object at 0x103eb6990>, 'receive_email': True, 'id': None}
ipdb> data.save()

*** InternalError: current transaction is aborted, commands ignored until end of transaction block

在详细的跟踪（包括sql）中，我得到：

我已经尝试将这些命令分别输入dbshell，但我看不出问题所在。在

有什么想法吗？在

当我遇到添加特殊字段或创建用户时执行任何特殊操作时，我宁愿避免覆盖User模型，并执行以下操作：

• 您可以创建一个新模型，例如Profile，并向用户提供一个OneToOneField
• 将所需的字段添加到该概要文件模型中，例如（tlf、country、language、log…）
• 在创建时添加任何特殊操作，例如保存日志、存储更多信息。。。。在
• 创建管理员py要在管理此模型（概要文件）的同时管理django admin中的用户

剖面模型示例

class Profile(models.Model):
    user = models.OneToOneField(User)
    phone = models.CharField(max_length=255, blank=True, null=True, verbose_name='phone')
    description = models.TextField(blank=True, verbose_name='descripction')
    ...
    ...
    def not_first_log(self):  
       # Just a tiny example of a function to mark user as first-logged
       self.first_log = False
       self.save()

    class Meta:
        ordering = ['user']
        verbose_name = 'user'
        verbose_name_plural = 'users'

---

管理员py示例

^{pr2}$

创建用户并为其添加个人资料

# Create user
username = 'TestUser'
email = 'test@example.com'
passw = '1234'  
new_user = User.objects.create_user(username, email, passw)

# Create profile
phone = '654654654'
desc = 'Test user profile'
new_profile = Profile(user=new_user, phone = phone, description=desc)
new_profile.profile_role = new_u_prole
new_profile.user = new_user

# Save profile and user
new_profile.save()
new_profile.not_first_log()
new_user.save()

---

现在，您将把这个概要模型附加到每个用户，您可以添加您希望分析模型的字段，例如，如果您使：

user = User.objects.get(id=1)

您可以通过以下操作访问他的个人资料：

user.profile

调用任何函数

user.profile.function_name

您还可以获取配置文件并执行profile.user

我知道您试图重写User模型，但我很肯定这是一种不太复杂和易于管理的方法，可以添加新的字段、操作或任何您需要的东西
