Django:重新启动后出现“没有名为context_processors的模块”错误

python

我有一个可以在我的PC上运行的Django站点,并且在加载后可以在服务器上短暂地工作。我注意到我的服务器安装了Django 1.6,并升级到了1.8。

重新启动后,网站上的所有页面均未加载,并且出现错误:

ImportError没有名为context_processors的模块

我通读了有关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_PROCESSORSsettings.py

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

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

还有其他人遇到吗?我在正确的轨道上吗?我需要更改设置吗?我真的无法确定这是Django还是allauth问题,因此不确定从哪里开始。

任何帮助表示赞赏!

问题是升级到Django 1.8后,在settings.py中没有按要求设置模板设置。我还不清楚为什么它可以在使用Django服务器的PC上运行。

从allauth文档中,我将其粘贴到设置文件中:

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',
            ],
        },
    },
]

并将我的旧TEMPLATE_DIRS设置的内容复制到TEMPLATES的DIRS定义中。最终结果如下所示:

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更新的文档,context_processors现在需要在TEMPLATES设置中指定而不是在TEMPLATE_CONTEXT_PROCESSORS设置中。
