Question

views.py：

コードのエラーがある

def register(request): 
    flag = True 
    possible = 'abcdefghijklmnopqrstuvwxyz' 
    token = '' 
    tempToken = '' 

    current_datetime = datetime.datetime.now() 

    user = UsersModelForm() 
    if request.method == 'POST': 
     userf = UsersModelForm(request.POST) 
     username = userf.data['username'] 
     password = userf.data['password'] 
     passwordrepeat = userf.data['passwordrepeat'] 
     email = userf.data['email'] 

     tempSalt = bcrypt.gensalt() 
     password = bcrypt.hashpw(password,tempSalt) 
     passwordrepeat = bcrypt.hashpw(passwordrepeat,tempSalt) 

     if password != passwordrepeat: 
      flag = False 
      passVariable = {'user':user, 'flag': False} 
      return render_to_response('register.html', passVariable, context_instance=RequestContext(request)) 

     elif password == passwordrepeat: 
      for i in range(1,10): 
       temp = random.choice(possible) 
       token = token + temp 

      if userf.is_valid(): 
       check = userf.save(commit=False) 
       check.email_token = token 
       check.email_token_expiry = current_datetime + timedelta(1) 
       check.password = password 
       check.passwordrepeat = passwordrepeat 
       check.save() 
       subject, from_email, to = 'hello', 'xxx@gmail.com', 'xxx@yahoo.com' 
       text_content = 'This is an important message.' 
       html_content = '<a href="http://127.0.0.1:8000/confirmemail/' + token + '">Click this link to confirm email</a>' 
       msg = EmailMultiAlternatives(subject, text_content, from_email, [to]) 
       msg.attach_alternative(html_content, "text/html") 
       msg.send() 
       return render_to_response('index.html', {}, context_instance=RequestContext(request)) 

    else: 
     return render_to_response('register.html', {"user": user, 'flag': True}, context_instance=RequestContext(request)) 

？

誰かが私の手助けをしてくれたら大変感謝していますか？

Answer 1

はpassword == passwordrepeatしかしuserf.is_valid()がFalseのときに何が起こるか考えてみてください。執行はどこに行きますか？
