python - Django：在用户配置文件的帐户更新中添加和保存新数据

Question

我正在尝试添加新信息，例如与用户相关的 Facebook 帐户。我没有在注册表单中添加它，因为它不是强制性的，也不需要在那里，但如果用户想要添加它，可以在帐户更新中找到它作为要填写的空白字段的选项。

我的问题是，我已将 facebook 帐户添加到帐户更新配置文件中，但是在我提交更新按钮后，页面被刷新并且数据未保存并且在 DB 中不可用。

这是models.py

class Profile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    image = models.ImageField(default='default.jpg', upload_to='profile_pics')

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

    def save(self, *args, **kwargs):
        super(Profile, self).save(*args, **kwargs)

        img = Image.open(self.image.path)

这是views.py

def register(request):
    if request.method == 'POST':
        form = UserRegisterForm(request.POST)
        if form.is_valid():
            form.save()
            username = form.cleaned_data.get('username')
            messages.success(
                request, f'Your account has been created! You are now able to log in')
            return redirect('login')
    else:
        form = UserRegisterForm()
    return render(request, 'register.html', {'form': form})

@login_required
def profile(request):
    if request.method == 'POST':
        u_form = UserUpdateForm(request.POST, instance=request.user)
        p_form = ProfileUpdateForm(request.POST,
                                   request.FILES,
                                   instance=request.user.profile)
        if u_form.is_valid() and p_form.is_valid():
            u_form.save()
            p_form.save()
            messages.success(request, f'Your account has been updated!')
            return redirect('profile')

    else:
        u_form = UserUpdateForm(instance=request.user)
        p_form = ProfileUpdateForm(instance=request.user.profile)

    context = {
        'u_form': u_form,
        'p_form': p_form
    }

    return render(request, 'profile.html', context)

这是forms.py

class UserRegisterForm(UserCreationForm):
    email = forms.EmailField()
    first_name = forms.CharField()
    last_name = forms.CharField()

    class Meta:
        model = User
        fields = ['username', 'first_name', 'last_name',
                  'email', 'password1', 'password2']

    def clean_email(self):
        email = self.cleaned_data.get("email")
        user_count = User.objects.filter(email=email).count()
        if user_count > 0:
            raise forms.ValidationError(
                "This email has already been registered. Please check and try again or reset your password")
        return email

class UserUpdateForm(forms.ModelForm):
    email = forms.EmailField()
    facebook_account = forms.CharField(required=False)

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

class ProfileUpdateForm(forms.ModelForm):
    class Meta:
        model = Profile
        fields = ['image']

这是信号.py

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

@receiver(post_save, sender=User)
def save_profile(sender, instance, **kwargs):
    instance.profile.save()

这是模板：

{% block content %}
    <div class="container" style="padding-top:100px">
        <div class="media">
            <img src="{{ user.profile.image.url }}" class="rounded-circle">
            <div class="media-body">
                <h2 class="account-heading">{{ user.username }}</h2>
                <p class="text-secondary">{{ user.email }}</p>
            </div>
        </div>
        <form method="POST" enctype="multipart/form-data">
            {% csrf_token %}
            <fieldset class="form-group">
                <legend class="border-bottom mb-4 pt-4">Profile Info</legend>
                {{ u_form|crispy }}
                {{ p_form|crispy }}
            </fieldset>
            <div class="form-group">
                <button class="btn btn-outline-info" type="submit">Update</button>
            </div>        
        </form>
    </div>
{% endblock content %}
