DJango形式与自定义__init__无法验证

Question

当我使用此代码自定义表单的窗口小部件时，它将无法验证。如果我评论WHERE，它就可以正常工作。

'------------------------------------------------------------
' Expirig_Click
'
'------------------------------------------------------------
Private Sub Expirig_Click()
On Error GoTo Expirig_Click_Err


    DoCmd.OpenReport "Expiring", acViewPreview, "", "[DuesExpire]=[TempVars]![tempExpirationDate] And [Type]=[TempVars]![tempType]", acNormal
    TempVars.Add "tempType", Combo164
    TempVars.Add "tempExpirationDate", CutoffDate
    DoCmd.OpenReport "Expiring", acViewReport, "", "[DuesExpire]=[TempVars]![tempExpirationDate] And [Type]=[TempVars]![tempType]", acNormal


Expirig_Click_Exit:
    Exit Sub

ExpirigLabels_Click_Err:
    MsgBox Error$
    Resume Expirig_Click_Exit

End Sub

我已经能够解决这个问题了，工作表单（没有 init ）和无效表单之间的区别是：

init ：

的无效表单

def __init__(..)

有效表格：

class CommentForm(forms.Form):
    def __init__(self, *args, **kwargs):
        self.wysiwyg = kwargs.pop('wysiwyg', False)

        super(CommentForm, self).__init__()
        if self.wysiwyg:
            self.fields['comment_text'].widget = SummernoteWidget()
        else:
            self.fields['comment_text'].widget = forms.Textarea(attrs={'rows':2})

    comment_text = forms.CharField()

是否存在问题以及如何解决？

谢谢！

试试这个..可能有效

class CommentForm(forms.Form):
def __init__(self, *args, **kwargs):
    try:
        self.wysiwyg = kwargs['wysiwyg']
    except KeyError:
        self.wysiwyg = None

    super(CommentForm, self).__init__(*args, **kwargs)
    if self.wysiwyg:
        self.fields['comment_text'].widget = SummernoteWidget()
    else:
        self.fields['comment_text'].widget = forms.Textarea(attrs={'rows':2})

comment_text = forms.CharField()
