Question

所以我刚创建了一个表单并不断收到此错误，为什么？我在检查表单是否有效后正确使用了Cleaned_data，对吗？

这是我的forms.py:

class UserForm(forms.ModelForm):
password = forms.CharField(widget=forms.PasswordInput)
username = forms.CharField(max_length=10)
email = forms.EmailField()

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

这是我的views.py：

class UserFormView(View):
form_class = UserForm
template_name = 'Home/index.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 = form.Cleaned_data['username']
        password = form.Cleaned_data['password']
        user.set_password(password)
        user.save()

        user = authenticate(username=username, password=password)
        if user is not None:
            if user.is_active:
                login(request, user)
                return redirect('Home:Dashboard')

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

我的urls.py:

urlpatterns = [
url(r'^$', views.index, name='index'),
url(r'^register$', views.UserFormView.as_view(), name='register'),]

和表单位置：

<form action="/register" method="post">
    {% csrf_token %}
<ul class="contactList">
    <li id="username1" class="contact">{{ form.username }}</li>
    <li id="email1" class="contact">{{ form.email }}</li>
    <li id="password1" class="contact">{{ form.password }}</li>
</ul>
<input type="submit" value="Submit">
</form>

关于这个问题还有其他主题，但我无法从中得到任何帮助，因为大多数人都没有包含if form.is_valid（），但在我的情况下我做了。

使用form.cleaned_data.get('username')代替form.Cleaned_data

修改使用FormView

from django.views.generic.edit import FormView class UserFormView(FormView): form_class = UserForm template_name = 'Home/index.html' def form_valid(self, form): user = form.save(commit=False) username = form.cleaned_data.get('username') ...

get_form_class返回表单的类，即UserForm。你需要的是那个类的一个对象。该类没有任何属性cleaned_data。

＆＃39;用户窗体＆＃39;对象没有属性＆＃39; Cleaned_data＆＃39;
