使用Django-Registration扩展用户模型

时间:2013-02-08 01:23:04

标签: django model extend django-registration

Django版本:4.0.2 Django-Registration版本:0.8 应用名称:userAccounts

问题: 我试图创建一个名为教授的用户类型来扩展用户模型。我可以完成注册过程,问题是只有用户保存在DB上,教授表保持空白。所以我认为问题可能出在save方法中。关于可能出现什么问题的一些线索?

SETTINGS.PY

AUTH_PROFILE_MODULE = "userAccounts.Professor"

MODELS.PY - 在这里,我创建了从用户和示例字段扩展的模型

from django.db import models
from django.contrib.auth.models import User

class Professor(models.Model):
  user = models.ForeignKey(User, unique=True)
  exampleField = models.CharField(max_length=100)

FORMS.PY - 保存用户后,我会在教授表中保存new_profile。

from django import forms
from registration.forms import RegistrationForm
from models import Professor
from registration.models import RegistrationProfile

class CustomRegistrationForm(RegistrationForm):
  exampleField = forms.CharField()

  def save(self, profile_callback=None):
    new_user = RegistrationProfile.objects.create_inactive_user(
        username=self.cleaned_data['username'],
        password=self.cleaned_data['password1'],
        email = self.cleaned_data['email'])
    new_professor = Professor(
        user=new_user, 
        exampleField=self.cleaned_data['exampleField'])
    new_professor.save()
    return new_user

问题已解决 - 解决方案

已经有好几天但我明白了! :d 我从shacker发现这篇文章: Django-Registration & Django-Profile, using your own custom form

显然在django-registration 0.8中save()方法无法覆盖。 所以,另外两个选项是: 使用信号或重写后端。

这两个解决方案都在我链接的帖子中解释。如果有人有同样的问题,我会尽力帮助评论:)

注意:使用信号工作正常但我在从表单中获取值时遇到了一些问题。所以我实现了后端方法,一切顺利。我强烈建议你阅读shacker的帖子,但是,如果你真的很沮丧,我的代码是:

my forms.py

class RegistrationForm(forms.Form):
    username = forms.RegexField(regex=r'^\w+$',
                            max_length=30,
                            widget=forms.TextInput(attrs=attrs_dict),
                            label=_("Username"),
                            error_messages={'invalid': _("This value must contain only letters, numbers and underscores.")})
    email = forms.EmailField(widget=forms.TextInput(attrs=dict(attrs_dict,
                                                           maxlength=75)),
                         label=_("Email address"))
    password1 = forms.CharField(widget=forms.PasswordInput(attrs=attrs_dict, render_value=False),
                            label=_("Password"))
    password2 = forms.CharField(widget=forms.PasswordInput(attrs=attrs_dict, render_value=False),
                            label=_("Password (again)"))

    #ADITIONAL FIELDS
    #they are passed to the backend as kwargs and there they are saved
    nombre = forms.CharField(widget=forms.TextInput(attrs=attrs_dict),
                            label=_("Nombre"))

__ init__.py(app / user_backend / __ init __。py)

class DefaultBackend(object):
def register(self, request, **kwargs):
        username, email, password, nombre = kwargs['username'], kwargs['email'], kwargs['password1'], kwargs['nombre']
        if Site._meta.installed:
            site = Site.objects.get_current()
        else:
            site = RequestSite(request)
        new_user = RegistrationProfile.objects.create_inactive_user(username, email,
                                                                password, site)
        signals.user_registered.send(sender=self.__class__,
                                 user=new_user,
                                 request=request)

        usuario(user = User.objects.get(username=new_user.username), nombre=nombre).save()
        return new_user
此行前

root URLS.PY - > url(r'profiles /',include('profiles.urls')),

    url(r'^accounts/registrar_usuario/$',
'registration.views.register',
{'backend': 'Hesperides.apps.accounts.user_regbackend.DefaultBackend','form_class':user_RegistrationForm},        
name='registration_register'
),
