python - Django - 清理表单数据时出现 AttributeError 'User' 对象没有属性 'cleaned_data'

Question

我试图在 Django 中制作一个用户注册页面。一切都很顺利。但是当我提交表单数据时，我收到以下错误

AttributeError 'User' object has no attribute 'cleaned_data'

Image of that AttributeError

我在 stackoverflow 上搜索，发现 object.cleanded_data 应该放在 object.is_valid() 之后，否则应该面临 AttributeError。但我在检查 is_valid() 后仍然出现错误。我的代码:

View .py

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})

表单.py

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"]

我找不到我哪里出错了。

Answer 1

form.save() 的结果是模型的实例，而不是表单。您应该正在访问 form.cleaned_data。

但是，无需在此处获取用户名，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()
