ImportError：無法導入名稱'UserForm'

Question

我正在使用與我已經在不同項目中工作的代碼非常相似，因此我無法真正指出問題，但它看起來是來自某個我的網址與視圖有關嗎？除此之外，我不確定爲什麼會出現此錯誤。請幫忙。

錯誤回溯：

    File "/Users/garrettlove/Desktop/colors/accounts/views.py", line 2, in <module> 
    from accounts.forms import UserForm 
ImportError: cannot import name 'UserForm' 

Form.py：

from django import forms 
from django.contrib.auth.models import User 
from accounts.models import User 

class UserFrom(forms.ModelForm): 
    password = forms.CharField(widget=forms.PasswordInput()) 

    class Meta(): 
     model = User 
     fields = ('username','email','password') 

Views.py：

from django.shortcuts import render 
from accounts.forms import UserForm 

from django.contrib.auth import authenticate,login,logout 
from django.http import HttpResponseRedirect, HttpResponse 
from django.core.urlresolvers import reverse 
from django.contrib.auth.decorators import login_required 

# Create your views here. 
def user_login(request): 
    if request.method == 'POST': 
     username = request.POST.get('username') 
     password = request.POST.get('password') 

     user = authenticate(username=username,password=password) 

     if user: 
      if user.is_active: 
       login(request.user) 
       return HttpResponseRedirect(reverse('index')) 
      else: 
       return HttpResponse("Account now active") 

     else: 
      print("Login Unsuccessful") 
      return HttpResponse("Your username and/or password are not correct") 

    else: 
     return render(request,'accounts/login.html',{}) 

def register(request): 
    registered = False 

    if request.method == 'POST': 
     user_form = UserForm(data=request.POST) 

     if user_form.is_valid(): 
      user = user_form.save() 
      user.set_password(user.password) 

      registered = True 
     else: 
      print(user_form.errors) 

    else: 
     user_form = UserForm() 

    return render(request,'accounts/register.html',{'user_form':user_form,'registered':registered}) 

@login_required 
def user_logout(request): 
    logout(request) 
    return HttpResponseRedirect(reverse('index')) 

應用urls.py：

from django.conf.urls import url 
from accounts import views 

app_name = 'accounts' 

urlpatterns = [ 
    url(r'^register/$',views.register,name='register'), 
    url(r'^login/$',views.user_login,name='user_login'), 
    url(r'^logout/',views.user_logout,name='user_logout'), 
] 

項目urls.py：

from django.conf.urls import url 
from django.contrib import admin 
from django.conf.urls import include 
from accounts import views 
#from colorsets import views 

urlpatterns = [ 
    url(r'^admin/', admin.site.urls), 
# url(r'^$',views.index,name='index'), 
    url(r'^accounts/',include('accounts.urls')), 
] 

讓我知道如果你需要看別的。謝謝。

Answer 1

您在forms.py中有錯字。您有UserFrom而不是UserForm。

Answer 2

，你認爲它從你的urls.py來幽州，但

您的跟蹤表明 File "/Users/garrettlove/Desktop/colors/accounts/views.py", line 2, in <module> from accounts.forms import UserForm

這樣的錯誤是從2號線view.py未來....

1) from django.shortcuts import render 
2) from accounts.forms import UserForm 
3) 
4) from django.contrib.auth import authenticate,login,logout 

仔細檢查您的導入...如果需要，使用django交互式shell（運行每一行以查看它是否有效）
