Django视图抛出HttpResponseError

我只是尝试将视图映射到

url.py

中的路径，但当我尝试映射时，它会抛出以下错误：

Registration didn't return an HttpResponse object

url.py

urlpatterns = patterns('',
    (r'^Register/$', Registration),
    (r'^Newuser/$', ProcessRegistration),
)

def Registration(request):
    RegForm = RegistrationForm(request.POST or None)
    if request.method == 'POST':
        if RegForm.is_valid():
            clearUserName = RegForm.cleaned_data['userNm']   
            clearPass = RegForm.cleaned_data['userPass']
            RegForm.save()
            try:
                return HttpResponseRedirect('/Newuser/?userNm=' + clearUserName)
            except:
                raise ValidationError(('Invalid request'), code='300')    ## [ TODO ]: add a custom error page here.
    else:
        RegForm = RegistrationForm()

        return render(request, 'VA/reuse/register.html', {
            'RegForm': RegForm 
        })

def ProcessRegistration(request):
    clearUserName = request.GET.get('userNm')
    return HttpResponse("Wee")

视图.py

urlpatterns = patterns('',
    (r'^Register/$', Registration),
    (r'^Newuser/$', ProcessRegistration),
)

def Registration(request):
    RegForm = RegistrationForm(request.POST or None)
    if request.method == 'POST':
        if RegForm.is_valid():
            clearUserName = RegForm.cleaned_data['userNm']   
            clearPass = RegForm.cleaned_data['userPass']
            RegForm.save()
            try:
                return HttpResponseRedirect('/Newuser/?userNm=' + clearUserName)
            except:
                raise ValidationError(('Invalid request'), code='300')    ## [ TODO ]: add a custom error page here.
    else:
        RegForm = RegistrationForm()

        return render(request, 'VA/reuse/register.html', {
            'RegForm': RegForm 
        })

def ProcessRegistration(request):
    clearUserName = request.GET.get('userNm')
    return HttpResponse("Wee")

当我访问

/Register

时，它抛出上述错误

---

知道它为什么不起作用吗？它返回一个响应

Wee

对于

userNm

的

验证器=[]

在我的models.py中搞砸了。我当时正在做：

  class Client(models.Model):
        userNm = models.EmailField(verbose_name="Email",max_length=50,unique=True,validators=[RegexValidator('^\w{6,50}$','format: invalid username','Invalid Entry')])
        userPass = models.CharField(verbose_name="Password", max_length=50)  

我将

userNm

声明更改为：

userNm = models.EmailField(verbose_name="Email",max_length=50,unique=True) 

---

等等，是抛出上述错误还是Wee的响应？是哪一个？上面的错误。它不会抛出应该是的“Wee”，对吗？如果

RegForm.is\u valid（）

返回false，则不会抛出。如果发生这种情况，函数将不返回任何内容，您将得到该错误。更不用说，

/Newuser/？userNm=…

将永远不会映射到

Newuser/$

，谢谢您的想法-解决了它。我会把答案贴出来。谢谢大卫
