Django:重启后"没有名为context_processors的模块"错误

Question

我有一个可以在我的电脑上运行的Django站点,并在加载后在我的服务器上工作.我注意到我的服务器有Django 1.6,我升级到1.8.

重新启动后,我的网站上没有任何页面加载,我收到错误:

ImportError没有名为context_processors的模块

我阅读了关于Django和allauth的文档.Django中提到,在1.8 context_processors移动和allauth说具体allauth标签不再需要在TEMPLATE_CONTEXT_PROCESSORS的settings.py.

Django:https://docs.djangoproject.com/en/1.8/ref/settings/

Allauth:https://django-allauth.readthedocs.org/en/latest/installation.html

其他人遇到这个？我是在正确的轨道上吗？我需要在设置中更改某些内容吗？我无法确定它是否是Django或allauth问题所以不确定从哪里开始.

任何帮助表示赞赏!

我遇到了同样的问题,但我从1.9.1升级到1.10.我发现设置有一点不同.

这是1.9.1的代码

TEMPLATES = [
{
    'BACKEND': 'django.template.backends.django.DjangoTemplates',
    'DIRS': [os.path.join(BASE_DIR, 'templates')],
    'APP_DIRS': True,
    'OPTIONS': {
        'context_processors': [
            'django.template.context_processors.debug',
            'django.template.context_processors.request',
            'django.core.context_processors.request',
            'django.contrib.auth.context_processors.auth',
            'django.contrib.messages.context_processors.messages',
        ],
    },
},
]

这是1.10的代码

TEMPLATES = [
{
    'BACKEND': 'django.template.backends.django.DjangoTemplates',
    'DIRS': [os.path.join(BASE_DIR, 'templates')],
    'APP_DIRS': True,
    'OPTIONS': {
        'context_processors': [
            'django.template.context_processors.debug',
            'django.template.context_processors.request',
            'django.contrib.auth.context_processors.auth',
            'django.contrib.messages.context_processors.messages',
        ],
    },
},
]

该行在django.core.context_processors.request1.10中无效.删除它,代码运行良好.

问题是我在升级到Django 1.8之后根据需要在settings.py中没有TEMPLATES设置.我不清楚为什么它使用Django服务器在我的电脑上工作.

从allauth docs中,我将其粘贴到我的设置文件中:

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                # Already defined Django-related contexts here

                # `allauth` needs this from django
                'django.template.context_processors.request',
            ],
        },
    },
]

并将旧TEMPLATE_DIRS设置的内容复制到TEMPLATES的DIRS定义中.最终结果如下:

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, 'templates')],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                # Already defined Django-related contexts here

                # `allauth` needs this from django
                'django.template.context_processors.request',
            ],
        },
    },
]

根据最近的allauth更新文档,context_processors现在需要在TEMPLATES设置中指定而不是TEMPLATE_CONTEXT_PROCESSORS设置.

感谢Joey Wilhelm指出我正确的方向.
