Djang中的验证错误

Question

我试图在django中修改userregistrationfrom，使每个电子邮件地址都是唯一的

我在django是个小傻瓜。所以，通过遵循教程和stuakoverflow问题，我写了这篇文章来检查电子邮件是否存在

顺便说一下，我在视图中写了所有的测试

from django.http import HttpResponse
from django.shortcuts import render
from django.contrib.auth.models import User
from django import forms
from django.contrib.auth.forms import UserCreationForm

class Signup(UserCreationForm):
    email = forms.EmailField(required=True)

    def clean_email(self):
        email = self.cleaned_data['email']
        try:
            user = User.objects.get(email=email)
        except User.DoesNotExist:
            return email
        raise forms.ValidationError("You have forgotten about Fred!")



def index(request):
    if request.method == "POST":
        signup = Signup(request.POST)

        if signup.is_valid():
            return HttpResponse("All is well")
        else:
            return render(request,'website/index.html',{'form':Signup})

    return render(request,'website/index.html',{'form':Signup()})

def private(request):
    return HttpResponse("Ok")

而且， 我得到了这个错误

为什么我会犯这个错误？怎么解决呢？在

好吧，我已经修复了这个错误：） 问题是 正在生成视图

所以正确的代码呢

from django.http import HttpResponse
from django.shortcuts import render
from django.contrib.auth.models import User
from django import forms
from django.contrib.auth.forms import UserCreationForm

class Signup(UserCreationForm):
    email = forms.EmailField(required=True)

    def clean_email(self):
        email = self.cleaned_data['email']

        try:
            u = User.objects.get(email=email)
        except User.DoesNotExist:
            return email

        raise forms.ValidationError("Error")




def index(request):
    if request.method == "POST":
        signup = Signup(request.POST)

        if signup.is_valid():
            return HttpResponse("All is well")
        else:
            return render(request,'website/index.html',{'form':signup})

    return render(request,'website/index.html',{'form':Signup()})
