用Django生成密碼保存用戶

Question

我正在嘗試使用生成的密碼和用戶名保存用戶，而且我遇到了一些麻煩。

我view.py看起來是這樣的：

... 
if request.method == "POST": 

    u = get_username(request.POST.get('first_name', '').lower() + "." + request.POST.get('last_name', '').lower()) 
    p = User.objects.make_random_password(length = 6) 

    form = PrincipalRegistrationForm(request.POST, request.FILES) 

    if form.is_valid(): 

     ... 

     new_user = form.save(uname = u, pword = p) 

     return HttpResponseRedirect("/path/to/site") 
... 

和我forms.py這樣的：

class PrincipalRegistrationForm(UserCreationForm): 

    first_name = forms.CharField(label = 'First name') 
    last_name = forms.CharField(label = 'Last name') 

    school = forms.ModelChoiceField(queryset = School.objects.all()) 
    profile_pic = forms.FileField(required=False) 



    def save(self,commit = True, uname = "unkown", pword = "unknown"): 

     user = super(PrincipalRegistrationForm, self).save(commit = False) 

     user.username = uname 
     user.set_password = make_password(pword) 

     user.first_name = self.cleaned_data['first_name'] 
     user.last_name = self.cleaned_data['last_name'] 


     if commit: 
      user.save() 
     return user 

    def __init__(self, *args, **kwargs): 
      super(PrincipalRegistrationForm, self).__init__(*args, **kwargs) 
      self.fields.pop('username') 
      self.fields.pop('password1') 
      self.fields.pop('password2') 

由輔助函數產生的用戶名，並取得了FNAME和LNAME的並且它會像代碼一樣發送到保存功能，它工作正常（如果我手動輸入密碼）。現在我想要密碼生成並保存爲用戶名，但我有問題。我得到這些錯誤：

Exception Type: KeyError 
Exception Value: u'password1' 
Exception Location: /usr/local/lib/python2.7/dist-packages/django/contrib/auth/forms.py in save, line 121 

感謝您的任何幫助，我欣賞任何關於如何編寫代碼或如果應該改變的東西的意見。

解決：

def save(self, commit = True, uname = "unkown", pword = "unknown"): 
    # Adding this line solved my problem 
    self.cleaned_data['password1'] = pword 

    user = super(PrincipalRegistrationForm, self).save(commit = False) 

    user.username = uname 
    user.first_name = self.cleaned_data['first_name'] 
    user.last_name = self.cleaned_data['last_name'] 

    if commit: 
     user.save() 
    return user

使用class Meta: exclude = ['somefield']和我的方式做正常保存之前改變形式的實例來解決問題。
