PYTHON / DJANGO:" SUser.user"必须是"用户"实例

我在向数据库添加新的自定义用户时遇到问题。我知道在互联网上有一些关于它的线索,但我无法找到解决问题的方法。点击"提交"注册页面中的按钮,模板在这里:

{% extends 'strona/Main.html' %}
{% block body %}
< form action="" method="post" enctype="multipart/form-data" >
    {% csrf_token %}
    {% for field in form %}
        {{ field.label_tag }}
        < /br >
        {{ field }}
        < /br >
        < /br >
    {% endfor %}
    < button type="submit" class="btn btn-success">Submit</button >
< /form >
{% endblock %}

它一直说:&#34;无法分配&#34;&lt; SimpleLazyObject:&lt; django.contrib.auth.models.AnonymousUser对象位于0x038B5A70&gt;&gt;&#34;:&#34; SUser.user&#34;必须是&#34;用户&#34; 。实例&#34;

源代码:

VIEWS.PY

class RegPanelView(View):
panel = RegPanel
template_name = 'strona/RegistrationTemp.html'
registration = None

def get(self, request):
    form = self.panel(None)
    return render(request, self.template_name, {'form': form})

def post(self, request):
    # form = self.panel(data=request.POST)
    form = self.panel(request.POST)

    if form.is_valid():
        # user = form.save(commit=False)

        # username = form.cleaned_data['username']
        password1 = form.cleaned_data['password1']
        password2 = form.cleaned_data['password2']

        if password1 == password2:

            newuser = form.save(commit=False)
            newuser.user = request.user
            newuser.save()

            return redirect('strona:index')
    return render(request, self.template_name, {'form': form})

MODELS.PY

class SUser(models.Model):
# User = user_model()

class RegPanel(UserCreationForm):

# password = forms.CharField(max_length=16, widget=forms.PasswordInput)
# first_name = forms.CharField(max_length=100, required=False)
# last_name = forms.CharField(max_length=100, required=False)
# is_staff = forms.BooleanField(required=False)

# birthday = forms.DateField(required=False)

class Meta:
    model = SUser
    fields = ['username', 'is_staff', 'first_name', 'last_name']





def save(self, commit=True):
    user = super(UserCreationForm, self).save(commit=False)
    # user.set_password(self.cleaned_data["passwosrd1"])
    if commit:



        user.set_password(self.cleaned_data["password1"])
        user.save()
        # if commit:

    return user

请有人帮帮我吗? 亲切的问候。

Django延迟加载request.user,以便它可以是UserAnonymousUser,具体取决于身份验证状态。

if request.user.is_authenticated(): #then request.user will be `User` instance
    newuser = form.save(commit=False)
    newuser.user = request.user
    newuser.save()
