Here is a nice tutorial that is perhaps a bit more helpful than the documentation if you're struggling: http://whoisnicoleharris.com/2015/01/06/implementing-django-formsets.html

这是一个很好的教程，如果你正在努力，可能比文档更有帮助：http：//whoisnicoleharris.com/2015/01/06/implementing-django-formsets.html

It goes through using formsets which allow you to have and use more than one form of the same type on a page. And also shows you a JQuery plugin that allows you to add and remove forms dynamically.

它通过使用formsets，允许您在页面上拥有和使用多个相同类型的表单。并且还向您展示了一个JQuery插件，允许您动态添加和删除表单。
