DJango表单与自定义__init__不验证 [英] DJango form with custom __init__ not validating

问题描述

当我使用这个代码自定义窗体的窗口小部件时，它不会被验证。如果我注释掉 def __init __（..）它可以正常工作。

When I use this code to customize my form's widget, it will not validate. If I comment out def __init__(..) it works fine.

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()

我已经能够解决这个问题，工作表单（无 init ）与无效表单之间的区别是这样的：

I've been able to troubleshoot this far, and the difference between the working form (no init) and the invalid form, is this:

不正确的格式与 init ：

CommentForm bound=False, valid=Unknown, fields=(comment_text)

形式：

CommentForm bound=True, valid=Unknown, fields=(comment_text)

是否有问题，我该如何解决？

Is bound the problem and how do I fix it?

谢谢！

推荐答案

尝试这个..可能会工作

Try this .. might work

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()
