动态更新ModelForm中ModelMultipleChoiceField的查询集

Question

我试图在ModelForm中更新ModelMultipleChoiceField的查询集.

BaseWriteForm是一个ModelForm,我的类如下所示:

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')

在这种情况下,我有:'MyWriteForm'对象没有属性'字段'

谢谢 !

只需在super()调用()之后移动它.

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