LinguaPlone 使用 MultiSelect 小部件来选择多种语言。像 InOut 小部件甚至 MultiCheckBox 小部件这样的东西将是一个更好的用户界面,因为很难从一长串列表中看到所有选定的语言。
我尝试使用以下方法覆盖 FormFields:
form_fields['available_languages'].custom_widget = MultiCheckBoxWidget
正如 zope.formlib 文档中所建议的那样,但我得到了如下回溯:
Traceback (innermost last):
Module ZPublisher.Publish, line 128, in publish

如何覆盖默认小部件?
