Question

我正在尝试在django中扩展用户个人资料，以便用户可以添加个人资料照片和生日日期，我正在使用django-allauth进行用户身份验证。我目前正在关注一个参考，但是为了参考，使用了新的用户注册而没有涉及django-allauth。因此，我已经实现了代码，但在一个点上存货，我无法确定将这一特定代码行放在何处

# Create the user profile
profile = Profile.objects.create(user=new_user)

下面是配置文件编辑代码的模型

class Profile(models.Model):
    user = models.OneToOneField(settings.AUTH_USER_MODEL)
    date_of_birth = models.DateField(blank=True, null=True)
    photo = models.ImageField(
            upload_to= upload_location,
            null = True,
            blank = True,
            height_field = "height_field",
            width_field = "width_field")

    def __str__(self):
        return 'Profile for user {}'.format(self.user.username)

Form.py

class UserEditForm(forms.ModelForm):
    username = forms.CharField(required=True)
    email = forms.EmailField(required=True)
    first_name = forms.CharField(required=False)
    last_name = forms.CharField(required=False)

    class Meta:
        model = User
        fields = ['first_name', 'last_name', 'username', 'email']

class ProfileEditForm(forms.ModelForm):
    """docstring for ProfileEditForm."""
    class Meta:
        model = Profile
        fields = ['date_of_birth', 'photo']

查看

def edit(request):
    if request.method == 'POST':
        user_form = UserEditForm(instance = request.user, data = request.POST)
        profile_form = ProfileEditForm(instance = request.user.profile, data = request.POST, files = request.FILES)

        if user_form.is_valid() and profile_form.is_valid():
            user_form.save()
            profile_form.save()

    else:
        user_form = UserEditForm(instance= request.user)
        profile_form = ProfileEditForm(instance=request.user.profile)

   return render(request, 'account/edit.html',
    {'user_form': user_form, 'profile_form': profile_form})

如果我尝试运行代码，我会收到错误User has no profile.，根据请求会提供更多代码。

网址

url(r'^profile/edit/$', views.edit, name='update_profile'),

模板

<form method="POST" action="." class="" enctype="multipart/form-data"/>
    {% csrf_token %}
    {{ user_form.as_p }}
    {{ profile_form.as_p }}
    <input type="submit" name="submit" value="update">

</form>

Answer 1

在您的视图中，添加（或添加到其他地方，然后导入）：

def load_profile(user):
  try:
    return user.profile
  except:  # this is not great, but trying to keep it simple
    profile = Profile.objects.create(user=user)
    return profile

然后更改您的查看功能，使用load_profile(request.user)代替request.user.profile。

查看

def edit(request): profile = load_profile(request.user) if request.method == 'POST': user_form = UserEditForm( instance=request.user, data=request.POST, ) profile_form = ProfileEditForm( instance=profile, data=request.POST, files=request.FILES, ) if user_form.is_valid() and profile_form.is_valid(): user_form.save() profile_form.save() else: user_form = UserEditForm(instance=request.user) profile_form = ProfileEditForm(instance=profile) return render( request, 'account/edit.html', {'user_form': user_form, 'profile_form': profile_form} )

Answer 2

由于您的错误告诉用户个人资料不存在：在view：

中

def edit(request):
    if request.method == 'POST':
        profile_form = ProfileEditForm(request.POST, request.FILES)

        if profile_form.is_valid():
            instance = profile_form.save(commit=False)
            instance.user = request.user
            instance.save()
            return # add here

    else:
        profile_form = ProfileEditForm()

    return render(request, 'account/edit.html', {'profile_form': profile_form})

它会起作用。
