通常，什么会导致build_attrs（）收到意外的关键字参数'id'错误？
尤其是在我的项目从一台服务器迁移到另一台服务器后，我会遇到此错误。所有模板都呈现得很好。 我不知道在哪里搜索以进行修复。模板是否会引发错误？

答案 0 :(得分：1)
Django 1.11引入了template-based widget rendering。 build_attrs错误可能是由需要更新的表单窗口小部件引起的。
对于您而言，回溯向您显示错误发生在geolocator/intranet/widgets.py的第77行上的小部件中。
答案 1 :(得分：0)
最后我找到了答案。在我的小部件中，我必须更改代码，如下所示：
local_attrs=self.attrs
local_attrs['id'] = self.year_field % id_
s = Select(choices=month_choices)
select_html = s.render(self.month_field % name, month_val, local_attrs)
output.append(select_html)
