Django - 获取AttributeError'User'对象在清理表单数据时没有属性'cleaning_data'

Question

我试图在Django中创建一个用户注册页面。一切都很顺利。但是当我提交表单数据时，我得到以下错误

AttributeError'User'对象没有属性'cleaning_data'

Image of that AttributeError

我在stackoverflow上搜索并发现object.cleanded_data应该放在object.is_valid（）之后，否则应该面对AttributeError。但是在检查后is_valid（）仍然出现错误后我放置了它。我的代码：

views.朋友

class UserFormView(View):
    form_class = UserForm
    template_name = "music/registration_form.html"

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

    def post(self, request):
        form = self.form_class(request.POST)

        if form.is_valid():
            user = form.save(commit=False)
            username = user.cleaned_data["username"]
            password = user.cleaned_data["password"]
            user.set_password(password)
            user.username = username
            user.save()

            user = authenticate(username= username, password= password)

            if user is not None:
                if user.is_active:
                    login(request, user)
                    return  redirect("music:index")

        return render(request, self.template_name, {"form": form})

forms.朋友

from django.contrib.auth.models import User
from django import forms

class UserForm(forms.ModelForm):
    password = forms.CharField(widget=forms.PasswordInput)

    class Meta:
        model = User
        fields = ["username", "email", "password"]

我无法找到我犯错误的地方。

form.save()的结果是模型的一个实例，而不是形式。你应该访问form.cleaned_data。

但是，没有必要在此处获取用户名，因为表单已经设置了它。

user = form.save(commit=False)
password = form.cleaned_data["password"]
user.set_password(password)
user.save()
