尝试访问我的博客或/admin页面时收到一个非常奇怪的错误。
VariableDoesNotExist at /admin/
模板渲染期间出错：
In template /Library/Python/2.7/site-packages/grappelli_safe/templates/admin/base.html, error at line 19
这是一行：
<script type="text/javascript" src="
{% static "mezzanine/js/"|add:settings.JQUERY_FILENAME %}
"></script>
我不知道如何解决这个奇怪的错误。是什么导致了这个以及如何解决它？删除该行时，错误仍然存在。
编辑：
完整错误：

现在设置一个视图但我收到错误：
Failed lookup for key [jquery_filename] in u"[{'False': False,'None': None, 'True': True}, {u'params': {}}, {}, {}]"
我的views.py：
from django.conf import settings
from django.shortcuts import render_to_response
def home(request, template='templates/base.html'):
context = {'jquery_filename': settings.JQUERY_FILENAME}
return render_to_response(template, context)
base.html文件：
<script src="{% static "mezzanine/js/"|add:jquery_filename %}"></script>
