動態更新ModelForm中ModelMultipleChoiceField的查詢集

Question

我正在嘗試更新ModelForm中ModelMultipleChoiceField的查詢集。

BaseWriteForm是一個的ModelForm，我的課看起來像如下：

class MyWriteForm(BaseWriteForm): 
    """The form for an authenticated user, to compose a message.""" 

    recipients = forms.ModelMultipleChoiceField(label=_('To'), 
               widget=forms.SelectMultiple(attrs={'class': 'chzn-select'}), 
               queryset = User.objects.all()) 


    def __init__(self, users_list, **kw): 
     self.fields['recipients'].queryset = User.objects.filter(pk__in=users_list) 

     super(BaseWriteForm, self).__init__(**kw) 


    class Meta(BaseWriteForm.Meta): 
     fields = ('recipients', 'subject', 'body') 

在這種情況下，我有： 'MyWriteForm' 對象有沒有屬性 '域'

謝謝！

只需在super() call（）之後移動它即可。

def __init__(self, users_list, **kw): 
    super(BaseWriteForm, self).__init__(**kw) 
    self.fields['recipients'].queryset = User.objects.filter(pk__in=users_list)
