我想基于的字典定义带有字段的表单类name: label。我尝试了以下方法，这些方法几乎奏效了。但是，在模板中渲染字段给了AttributeError: 'UnboundField' object has no attribute '__call__'。如何动态向表单添加字段？

        return render_template('cardcompare.tpl', record=record, form=form)

def build_form(name, record):
    class ContactForm(FlaskForm):

    def showform():
        form = ContactForm(request.form)

        if request.method == …
