姜戈。自动完成...它不查找搜索
Django. autocomplete... It doesn't look up the search
我是 Django 的新手，具有自动完成功能。我正在尝试使用自动完成搜索。我正在学习本教程：https://github.com/yourlabs/django-autocomplete-light/blob/master/docs/tutorial.rst
Django 没有给我任何错误。除了它实际上并不在搜索中寻找结果之外，所有的工作。相反，它给了我这个短语："the results could not be loaded"
在 html 中，在开发人员部分它给我以下错误：
第一次访问页面时 - GET http://dal-yourlabs.rhcloud.com/static/collected/admin/js/vendor/jquery/jquery.js net::ERR_NAME_NOT_RESOLVED
在搜索字段中键入时：jquery.min.js:2 GET http://127.0.0.1:8000/sc_site/dirdict-autocomplete/?q=ghj 500（内部服务器错误）
我不使用 get 方法，因为我正在 post 搜索数据库...我正在使用 post 方法。
我还尝试设置此代码：
进入模板 -
<script type="text/javascript" src="http://dal-yourlabs.rhcloud.com/static/collected/admin/js/vendor/jquery/jquery.js"></script>
和
into the base.html-<link src="/static/collected/autocomplete_light/vendor/select2/dist/css/select2.css" type="text/css" media="all" rel="stylesheet" />
<link src="/static/collected/autocomplete_light/select2.css" type="text/css" media="all" rel="stylesheet" />
<script type="text/javascript" src="/static/collected/autocomplete_light/autocomplete.init.js"></script>
<script type="text/javascript" src="/static/collected/autocomplete_light/select2.js"></script>
就像这个 post 中建议的那样：
但这并没有真正的帮助。我究竟做错了什么？
谢谢！
更新：
试图将自动完成文件加载到项目中...
做了以下：
在 settings.py:
STATIC_ROOT = "C:/sc_project/sc/sc_site/static"
STATIC_URL = '/static/'
之后在 cmd 中：
python manage.py collectstatic
现在我在静态文件夹中看到一堆文件："autocomplete.init.js, forward.js, jquery.init.js, jquery.post-setup.js, select2.css, select2.js"
但是我还是看到上面的错误:(.
我为这些 jquery 文件处理了一堆代码：
在 base.html:

我确实知道这是一团糟，我打算清理并更改一些地址，因为它们显然与我的项目无关，但我有这种讨厌的感觉，它不会有帮助:(
更新
清理了静态文件的脚本和链接。一般地址都是错误的。还剩下最后一个错误。
我下载了 firebug，但我通常不知道如何处理其中的信息：

如果有人在正确的方向引导我，那就太好了。我浏览了很多 Whosebug 论坛，但大多没有关于自动完成的答案，或者他们对我帮助不大...
