Python 生成注册表页时出错，AttributeError位于/register/'；注册执行'；对象没有属性'；清理数据'；

我正在使用Python 2.7.15&&Django 1.11.18构建一个注册页面，但仍然出现错误：

AttributeError at /register/
'RegisterForm' object has no attribute 'cleaned_data'

我浏览了其他非常类似的帖子，尝试了这些建议，但仍然没有得到一个实用的结果。在我看来，一切都井然有序，但事实并非如此。下面是我的代码，谢谢

Views.py看起来像：

def register_page(request):
    form = RegisterForm(request.POST or None)
    context = {
        "form": form
    }
    if form.is_valid():
        form.save()
        print(form.cleaned_data)
        username  = form.cleaned_data.get("username")
        email = form.cleaned_data.get("email")
        password = form.cleaned_data.get("password")
    new_user = User.objects.create_user(username, email, password)
    print(new_user)

    return render(request, "auth/register.html", context)

class RegisterForm(forms.Form):
username = forms.CharField()
email    = forms.EmailField()
password = forms.CharField(widget=forms.PasswordInput)
password2 = forms.CharField(label='Confirm password', widget=forms.PasswordInput)

def clean(self):
    data = self.cleaned_data
    password = self.cleaned_data.get('password')
    password2 = self.cleaned_data.get('password2')
    if password2 != password:
        raise forms.ValidationError("Passwords must match.")
    return data

   from django.conf.urls import url
from django.contrib import admin

from .views import home_page, about_page, contact_page, login_page, register_page

urlpatterns = [
    url(r'^$', home_page), 
    url(r'^about/$', about_page),
    url(r'^contact/$', contact_page),
    url(r'^login/$', login_page),
    url(r'^register/$', register_page),                  
    url(r'^admin/', admin.site.urls),
]

forms.py看起来像：

def register_page(request):
    form = RegisterForm(request.POST or None)
    context = {
        "form": form
    }
    if form.is_valid():
        form.save()
        print(form.cleaned_data)
        username  = form.cleaned_data.get("username")
        email = form.cleaned_data.get("email")
        password = form.cleaned_data.get("password")
    new_user = User.objects.create_user(username, email, password)
    print(new_user)

    return render(request, "auth/register.html", context)

class RegisterForm(forms.Form):
username = forms.CharField()
email    = forms.EmailField()
password = forms.CharField(widget=forms.PasswordInput)
password2 = forms.CharField(label='Confirm password', widget=forms.PasswordInput)

def clean(self):
    data = self.cleaned_data
    password = self.cleaned_data.get('password')
    password2 = self.cleaned_data.get('password2')
    if password2 != password:
        raise forms.ValidationError("Passwords must match.")
    return data

    url(r'^register/$', register_page),

url.py看起来像：

    form = RegisterForm(request.POST or None)
    context = {
        "form": form
    }
    if form.is_valid():

        print(form.cleaned_data)
        username  = form.cleaned_data.get("username")
        email = form.cleaned_data.get("email")
        password = form.cleaned_data.get("password")
    new_user = User.objects.create_user(username, email, password)
    print(new_user)

    return render(request, "auth/register.html", context)

def clean(self):
    data = self.cleaned_data
    password = self.cleaned_data.get('password')
    password2 = self.cleaned_data.get('password2')
    if password2 != password:
        raise forms.ValidationError("Passwords must match.")
    return data

   from django.conf.urls import url

    url(r'^register/$', register_page),                  
    url(r'^admin/', admin.site.urls),
]

下面是回溯 我在这里遗漏了什么？

在forms.py中，你说：

def clean(self):
    data = self.cleaned_data
....

但是

self.cleaned_data

是未定义的-您的示例中没有包含类似

self.cleaned_data=

---

因此，行

data=self.cleaned_data

抱怨它不知道

self.cleaned_data

是什么

请出示回溯。这个错误到底发生在哪里？它说第110行是问题所在：email=form.cleaned_data.get（“email”）Ok是有意义的，但我应该在两者之间加什么呢？这取决于具体情况，但可能是

super（）.clean（）

？
