Question

我有一个用Django 1.7编写的Django应用程序，我正在移植到Docker应用程序。我在容器中使用了Django 1.10。

当我浏览到/ admin / URI时，我得到以下异常：

KeyError at /admin/

u'user'

Request Method:     GET
Request URL:        http://10.3.101.206:9000/admin/
Django Version:     1.10

Exception Value:

61              {% else %}
62              <ul class="actionlist">
63              {% for entry in admin_log %}
64              <li class="{% if entry.is_addition %}addlink{% endif %}{% if entry.is_change %}changelink{% endif %}{% if entry.is_deletion %}deletelink{% endif %}">
65                  {% if entry.is_deletion or not entry.get_admin_url %}
66                      {{ entry.object_repr }}
67                  {% else %}
68                      <a href="{{ entry.get_admin_url }}">{{ entry.object_repr }}</a>

错误似乎出现在Django代码中，而不是我的代码中，因此我不确定问题是什么或如何修复它。

KeyError暗示无法找到user上下文变量。该变量仅可通过django.contrib.auth.context_processors.auth获得，默认情况下通常包含该变量。

您可以按照here所述的上下文处理器中包含它：

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [
            # insert your TEMPLATE_DIRS here
        ],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.contrib.auth.context_processors.auth',
                # ...list other context processors you will need...
            ],
        },
    },
]
