Question

我一直在关注Dmitry教程，以便使用附加字段扩展django-registration插件注册。用户现在可以注册，但不保存其他字段。我一直收到错误。

Django版本：1.4.2
  异常类型：InternalError异常值：当前事务中止，命令忽略直到事务块结束异常
  位置：/root/env27/lib/python2.7/site-packages/django/db/models/sql/compiler.py   在execute_sql中，第910行

同时查看postgresql日志，当我执行注册函数时，我会看到以下条目。

无法弄清楚可能存在什么问题，希望有人能指出我正确的方向。

原来解决这个问题很简单。在regbackendpy中对查询的轻微修改使其正常工作。

from dirapp.forms import UserRegistrationFormz
    from dirapp.models import UserProfile
    from django import forms

    def user_created(sender, user, request, **kwargs):
        form = UserRegistrationFormz(request.POST)
        **data = UserProfile.objects.get(user=user.id)**
        data.name = form.data['name']
        data.save()

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

无法在扩展的Django注册模块上保存额外字段
