Question

我正在关注这个（https://www.django-tips.com/tutorial/django-tutorial-with-twitter-app/1/?page=3）教程，用django创建一个twitter克隆应用程序。但在项目中，将通过django默认用户创建系统创建用户。

问题是，我想在创建用户时在userprofile表中创建一行。否则用户正在创建，我必须将其插入到访问项目管理部分的userprofile表中。我怎么能这样做？

模型看起来像这样：

from django.contrib.auth.models import User

class UserProfile(models.Model):
 user = models.OneToOneField(User, related_name='profile')
 relation = models.ManyToManyField(
     'self',
     through='Relation',
     symmetrical=False,
     related_name='related_to',
     default=None
 )
 def __unicode__(self):
    return self.user.get_full_name()

 class Relation(models.Model):
  follower = models.ForeignKey(UserProfile, related_name='follows')
  is_followed = models.ForeignKey(UserProfile, related_name='followers')
  follow_time = models.DateTimeField(auto_now_add=True)

  def __unicode__(self):
     return '%s follows %s' % (self.follower.user.username, self.is_followed.user.username)

  class Meta:
     unique_together = ('follower', 'is_followed')

教程还提到创建一个信号，但是他们还没有清除创建此文件的位置，所以我已经按照官方文档创建了signals.py文件。

def create_profile(sender, instance, created, **kwargs):
if created:
    UserProfile.objects.create(user=user)
post_save.connect(create_profile, sender=User)

所以，我陷入了这个阶段，我无法继续前进。提前谢谢。

Answer 1

您不必在UserProfile

之后创建信号文件

from django.auth.models import User
from django.db.models.signals import post_save
from django.dispatch import receiver

class UserProfile(models.Model):
    ....

@receiver(post_save, sender=User)
def create_profile(sender, instance, created, **kwargs):
    if created:
        UserProfile.objects.create(user=instance)

要在创建用户后（通过models.py）在userprofile表中创建一行，您可以从管理界面或从shell或在前端创建表单，然后POST并保存它。（我给你提供示例代码 - 其中的各种属性现在可能对您没用。只是为了您的理解。）

shell方法可以是这样的：

$ ./manage.py shell
>>> from django.contrib.auth import User
>>> from <package_profile>.models import UserProfile
>>> new_user = UserProfile(user_auth = new_user, name = name,...) # other whatever fields you want
>>> new_user.save()

表单方法可以是这样的：

    from django.shortcuts import render
    from django.http import HttpResponse
    from <package_profile>.models import USerProfile, Developer
    from django import forms
    from django.contrib.auth.decorators import login_required
    from django.contrib.auth.models import User

    @login_required
    def page(request):
    if request.POST:
        form = Form_inscription(request.POST)
        if form.is_valid():
            name     = form.cleaned_data['name']
            login    = form.cleaned_data['login']
            password = form.cleaned_data['password']

        # User auth details:-   
            new_user            = User.objects.create_user(username = login, password = password)
            new_user.is_active  = True
            new_user.email      = email
            new_user.first_name = name
            new_user.save()
            new_developer       = Developer(user_auth = new_user, name = name, email = email)
            new_developer.save()
            return HttpResponse("Developer added")
        else:
            return render(request, create_developer.html', {'form' : form})
    else:
        form = Form_inscription()
        return render(request,create_developer.html', {'form' : form})

    class Form_inscription(forms.Form):
        name     = forms.CharField(label="Name", max_length=30)
        login    = forms.CharField(label = "Login")
        email    = forms.EmailField(label = "Email")
        password = forms.CharField(label = "Password", widget = forms.PasswordInput)
        password_bis = forms.CharField(label = "Password Re-enter", widget = forms.PasswordInput)

        def clean(self): 
            cleaned_data = super(Form_inscription, self).clean()
            password = self.cleaned_data.get('password') 
            password_bis = self.cleaned_data.get('password_bis')
            if password and password_bis and password != password_bis:
                raise forms.ValidationError("Passwords are not identical.") 
            return self.cleaned_data

表单的相应html将是：

{% extends "base.html" %}
 {% block title_html %}
  Create Developer/User
{% endblock %}

{% block h1 %}
  Create Developer
{% endblock %}

{% block article_content %}
  <form method="POST">
   {% csrf_token %}
   <table>
    {{ form.as_table }}
   </table>
   <p><input type="submit" value="Create" /></p>
  </form>
{% endblock %}
