沒能得到初始數據Django的形式

Question

這裏是Django的形式是Django的用戶變化形式

class UserChangeForm(forms.ModelForm): 
    """A form for updating users. Includes all the fields on 
    the user, but replaces the password field with admin's 
    password hash display field. 
    """ 

    class Meta: 
     model = MyUser 
     fields = ('first_name', 'last_name', 'mobile' , 'gender') 
     widgets = { 
     'gender': forms.RadioSelect(), 
     } 

    def __init__(self, *args, **kwargs): 
     super(UserChangeForm, self).__init__(*args, **kwargs) 
     if self.request.user.is_authenticated(): 
      user = User.objects.get(email=self.request.user.email) 
      first_name = user.first_name 
      last_name = user.last_name 
      mobile = user.mobile 
      gender = user.gender 

     self.fields['first_name'].initial = first_name 
     self.fields['last_name'].initial = last_name 
     self.fields['mobile'].initial = mobile 
     self.fields['gender'].initial = gender 

這是我收到

'UserChangeForm' object has no attribute 'request' 

在這裏的錯誤是認爲

class UserProfileEditView(DetailView): 
    template_name = "edit_profile.html" 

    def get(self , request , *args , **kwargs): 
     context = {} 
     edit_form = UserChangeForm() 

     context['edit_form'] = edit_form 

     return render(request , self.template_name , context) 

這裏是回溯

File "C:\Python27\lib\site-packages\django\core\handlers\base.py" in get_response 
    132.      response = wrapped_callback(request, *callback_args, **callback_kwargs) 
File "C:\Python27\lib\site-packages\django\views\generic\base.py" in view 
    71.    return self.dispatch(request, *args, **kwargs) 
File "C:\Python27\lib\site-packages\django\views\generic\base.py" in dispatch 
    89.   return handler(request, *args, **kwargs) 
File "C:\Users\lenovo\Desktop\Grooved2\grooved\src\accounts\views.py" in get 
    54.   edit_form = UserChangeForm() 
File "C:\Users\lenovo\Desktop\Grooved2\grooved\src\accounts\forms.py" in __init__ 
    58.   if self.request.user.is_authenticated(): 

我怎樣才能得到django形式的字段的初始數據？ 謝謝

後MHassan的響應

這裏編輯的形式

def __init__(self, *args, **kwargs): 
     super(UserChangeForm, self).__init__(*args, **kwargs) 
     intial_data = self.kwargs.get('initial') 
     request = intial_data.get('request') 

     if self.request.user.is_authenticated(): 
      user = User.objects.get(email=request.user.email) 
      first_name = user.first_name 
      last_name = user.last_name 
      mobile = user.mobile 
      gender = user.gender 

     self.fields['first_name'].initial = first_name 
     self.fields['last_name'].initial = last_name 
     self.fields['mobile'].initial = mobile 
     self.fields['gender'].initial = gender 
     del self.fields['gender'].widget.choices[0] 

這裏是視圖

def get(self , request , *args , **kwargs): 
     context = {} 
     edit_form = UserChangeForm(initial={'request': request}) 

     context['edit_form'] = edit_form 

     return render(request , self.template_name , context) 

這裏回溯

File "C:\Python27\lib\site-packages\django\core\handlers\base.py" in get_response 
    132.      response = wrapped_callback(request, *callback_args, **callback_kwargs)

Answer 1

Django的request對象是默認不可用在Form類，所以你必須自己傳遞：

class UserChangeForm(forms.ModelForm): 
    def __init__(self, *args, **kwargs): 
     self.request = kwargs.pop('request', None) 
     # Call super() after deleting the extra kwargs. 
     super(UserChangeForm, self).__init__(*args, **kwargs) 
     # Other code 

，並通過它當您創建視圖的形式：

def update(request): 
    form = UserChangeForm(request=request)
