Question

我试图在我的Django（1.10）项目中使用django-autocomplete-light 3.2.1和python（3.5），我发现使用它有很大的困难。然后我尝试按照教程中显示的实时演示，将所有文件下拉到我的本地驱动器进行复制（如http://dal-yourlabs.rhcloud.com/select2_outside_admin/上的那个），但是徒劳无功。对我来说，我想让我的本地演示工作，以便我可以基于此工作我自己的。

具体来说，当我按照以下代码运行网站时，会显示NoReverseMatch at /select2_outside_admin/的错误，其中包含Reverse for 'linked_data' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []的说明我不知道出了什么问题。我附上了如下代码，如果您知道解决方案，请告知如何操作。非常感谢：
