登記表導入錯誤

我下面DjangoBook教程和我所遇到的第14章（用戶註冊）問題登記表導入錯誤

在django.contrib.auth.forms，有UserCreationForm類。我想在django.contrib.auth.forms

class RegisterForm(UserCreationForm): 
    email = forms.EmailField(label="Email") 
    fullname = forms.CharField(label="Full name") 

    class Meta: 
     model= User 
     fields = ("username","fullname","email",)

創建一個名爲RegisterForm

這是我RegisterForm類基於UserCreationForm一個新的類這是視圖功能

def register(request): 
    if request.method == 'POST': 
     form = UserCreationForm(request.POST) 
     if form.is_valid(): 
      new_user = form.save() 
      return HttpResponseRedirect("/books/") 
    else: 
     form = RegisterForm(UserCreationForm) 
    return render(request, "registration/register.html", { 
     'form': form, 
    })

我不知道爲什麼我得到一個ImportError，其中指出我無法在我的視圖中導入名稱RegisterForm，有人可以幫我解答。

這是我的堆棧跟蹤

你編輯過'django.contrib.auth.forms'來添加你的類嗎？什麼是完整的堆棧跟蹤？ – Rohan 2013-05-02 06:57:43

我很困惑 - UserCreationForm是RegisterForm的父級？爲什麼然後你發送視圖函數作爲參數（'form = RegisterForm（UserCreationForm）'）？ – 2013-05-02 06:58:11

@DenisMalinovsky我是Django的新手，我應該如何調用RegisterForm。 Rohan：是的，我已經添加了類到django.contrib.auth.forms – user2284926 2013-05-02 07:13:15

由於的Django 1.5有模塊django.contrib.auth.forms.

你可能想使用要強調這樣的事情對你的編輯器中沒有這樣的形式。如PyCharm。

儘管如此，點支架，您應該至少對Python瞭解Django的基本瞭解。你看，這些陳述

class RegisterForm(UserCreationForm)  
    ... 
# And then: 
form = RegisterForm(UserCreationForm)

很難從Python的角度來理解。

您正在編寫Python代碼。在Python中。你必須學習Python。是的，有可能以另一種方式行事，但這很難。
