每当我想访问它时，我一直在管理员中收到错误，并且在我在uWSGI中部署它时崩溃了。这是错误：

我已经尝试禁用我注册的所有管理网站，但我一直收到此错误消息。有什么想法吗？

我也得到了相同的日志消息，全新安装了django 1.10.6。和日志记录打开。我不是这方面的专家，但在Django-users邮件列表上询问question后，我发现了这一点。
正如您可以从Django logging documentation读取的那样，日志级别从最低优先级到最高优先级
这意味着，实际上“很高兴知道”低级信息，如果出现故障您将记录，否则您无法找到原因。
如果你看一下例外的第一行，就说
Exception while resolving variable 'is_popup' in template 'admin/login.html'
'admin / index.html'扩展'base_site.html'，它扩展了'base.html'，它有以下行（靠近文件的开头）：
<body class="{% if is_popup %}popup {% endif %}{% block bodyclass %}{% endblock %}"
data-admin-utc-offset="{% now "Z" %}">
<!-- Container -->
<div id="container">
{% if not is_popup %}
<!-- Header -->
<div id="header">
<div id="branding">
{% block branding %}{% endblock %}
</div>
你可以从django logging documentation看到，缺少模板变量导致从Django 1.9开始的DEBUG级别日志消息。
缺少模板变量的原因是django重用模板。在某些情况下，会定义一个模板变量'is_popup'，而django会以不同的方式呈现页面。当没有'is_popup'这样的变量时，django将跳过相关的行。即undefined和false在模板文件中用于比较相同。当然，您可以编写代码来检查变量是否存在，但它只是额外的代码行。无论如何，Django将跳过未定义的变量（核心代码中的一些尝试..异常模式）。
只需添加一个名为“django.template”的记录器，即可使日志级别为INFO。
'loggers': {
'django': {
'handlers': ['file'],
'level': 'DEBUG',
'propagate': True,
},
'django.template': {
'handlers': ['file'],
'level': 'INFO',
'propagate': True,
},
},

答案 2 :(得分：-4)
您应该将项目日志记录级别设置为不在debug.set中，以便信息可以正常工作。
'loggers': {
'django': {
'handlers': ['file', 'console'],
'level': os.getenv('DJANGO_LOG_LEVEL', 'INFO'),
'propagate': True,
},
},
