轻松扩展 Django 用户模型

我们的 UserProfile 级

使用 OneToOne 与默认 User 模型的关系创建 UserProfile 模型类：

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

class UserProfile(models.Model):
    user = models.OneToOneField(User, related_name='user')
    photo = FileField(verbose_name=_("Profile Picture"),
                      upload_to=upload_to("main.UserProfile.photo", "profiles"),
                      format="Image", max_length=255, null=True, blank=True)
    website = models.URLField(default='', blank=True)
    bio = models.TextField(default='', blank=True)
    phone = models.CharField(max_length=20, blank=True, default='')
    city = models.CharField(max_length=100, default='', blank=True)
    country = models.CharField(max_length=100, default='', blank=True)
    organization = models.CharField(max_length=100, default='', blank=True)

Django 信号在工作

使用 Django Signals，立即创建一个新的 UserProfile，创建一个 User 对象。此功能可以隐藏在同一文件中的 UserProfile 模型类下面，或者放在任何你喜欢的位置。我不在乎，因为你正确引用它。

def create_profile(sender, **kwargs):
    user = kwargs["instance"]
    if kwargs["created"]:
        user_profile = UserProfile(user=user)
        user_profile.save()
post_save.connect(create_profile, sender=User)

inlineformset_factory 来救援

现在为你的 views.py，你可能有这样的东西：

from django.shortcuts import render, HttpResponseRedirect
from django.contrib.auth.decorators import login_required
from django.contrib.auth.models import User
from .models import UserProfile
from .forms import UserForm
from django.forms.models import inlineformset_factory
from django.core.exceptions import PermissionDenied
@login_required() # only logged in users should access this
def edit_user(request, pk):
    # querying the User object with pk from url
    user = User.objects.get(pk=pk)

    # prepopulate UserProfileForm with retrieved user values from above.
    user_form = UserForm(instance=user)

    # The sorcery begins from here, see explanation https://blog.khophi.co/extending-django-user-model-userprofile-like-a-pro/
    ProfileInlineFormset = inlineformset_factory(User, UserProfile, fields=('website', 'bio', 'phone', 'city', 'country', 'organization'))
    formset = ProfileInlineFormset(instance=user)

    if request.user.is_authenticated() and request.user.id == user.id:
        if request.method == "POST":
            user_form = UserForm(request.POST, request.FILES, instance=user)
            formset = ProfileInlineFormset(request.POST, request.FILES, instance=user)

            if user_form.is_valid():
                created_user = user_form.save(commit=False)
                formset = ProfileInlineFormset(request.POST, request.FILES, instance=created_user)

                if formset.is_valid():
                    created_user.save()
                    formset.save()
                    return HttpResponseRedirect('/accounts/profile/')

        return render(request, "account/account_update.html", {
            "noodle": pk,
            "noodle_form": user_form,
            "formset": formset,
        })
    else:
        raise PermissionDenied

我们的模板

然后将所有内容吐到模板 account_update.html 中：

{% load material_form %}
<!-- Material form is just a materialize thing for django forms -->
<div class="col s12 m8 offset-m2">
      <div class="card">
        <div class="card-content">
        <h2 class="flow-text">Update your information</h2>
          <form action="." method="POST" class="padding">
            {% csrf_token %} {{ noodle_form.as_p }}
            <div class="divider"></div>
            {{ formset.management_form }}
                {{ formset.as_p }}
            <button type="submit" class="btn-floating btn-large waves-light waves-effect"><i class="large material-icons">done</i></button>
            <a href="#" onclick="window.history.back(); return false;" title="Cancel" class="btn-floating waves-effect waves-light red"><i class="material-icons">history</i></a>
 
        </form>
        </div>
    </div>
</div>
