错误：

AttributeError at / 'UserForm' object has no attribute 'get'

我无法调试这个错误！我忽略了我的代码很多次，但不能理解错误是在哪里产生的。请帮助我。提前感谢。

表单.py

class UserForm(forms.Form):
    username = forms.CharField()
    email = forms.EmailField()
    password1 = forms.PasswordInput()
    password2 = forms.PasswordInput()

    def clean(self):
        password1 = self.cleaned_data['password1']
        password2 = self.cleaned_data['password2']
        if password1 != password2:
            raise forms.ValidationError('Password Should Match')
        return self.cleaned_data

查看次数.py

def userview(request):
    if request.method == 'POST':
        form = UserForm(request.POST)
        if form.is_valid():
            username = form.cleaned_data['username']
            email = form.cleaned_data['email']
            password1 = form.cleaned_data['password1']
            user = User(username=username,email=email,password =password1)
            user.save()
            return HttpResponse('User Created')
    else:
        form = UserForm()
    return render(request,'home.html',{'form':form})

模板主页.html

<form method="post" id="post-form">
    {% csrf_token %}
    {{form.as_p}}
<input type='submit' value ='ok'>
</form>

按照指示，我已经提供了这个错误的完整追溯。我想我已经在views.py中定义了post方法，当该方法没有发布时，它将访问函数的else部分。但仍然不明白为什么会出现这样的错误。
