1. ALLOWED_HOSTS
DEBUG = True
ALLOWED_HOSTS = []
默认为一个空列表,代表此Django网站可以可以提供的主机/域名的字符串列表。当DEUG = True 和 ALLOWED_HOSTS 是空的时候,默认将对本机('localhost')进行验证
2.INSTALLED_APPS
![](https://images.cnblogs.com/OutliningIndicators/ContractedBlock.gif)
INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'app01', ]
django.contrib.admin —— 管理站点。
django.contrib.auth —— 认证系统。
django.contrib.contenttypes —— 用于内容类型的框架。
django.contrib.sessions —— 会话框架。
django.contrib.messages —— 消息框架。
django.contrib.staticfiles —— 管理静态文件的框架。
app01 是创建应用app的名字,如果项目创建了app则必须要添加app的名字
3.MIDDLEWARE_CLASSES
一个django 用到的中间件 class 名称的 tuple. 参阅 middleware 文档.
4.ROOT_URLCONF
默认值: Not defined
一个字符串,表示你的根 URLconf 的模块名. 举例来说:"mydjangoapps.urls".
5.TEMPLATE_DIRS
默认值: () (空的 tuple)
模板源文件目录列表,按搜索顺序. 注意要使用 Unix-风格的前置斜线(即'/')
6.WSGI_APPLICATION
WSGI_APPLICATION 所指定的即为 wsgi.py 中的全局变量 application。在 get_wsgi_application() 中实例化了 WSGIHandler, 并无其他操作.
7.STATIC_ROOT
运行上边提到的命令:python manage.py collectstatic 之后静态文件将要复制到的目录,这个目录只有在运行collectstatic时候才会用到,不能想当然的以为这个目录和MEDIA_ROOT的作用是相同的,否则在开发环境的时候可能一直无法找到静态文件。
8.STATIC_URL
设置的static file的起始url,这个只是在template里边引用到,这个参数和MEDIA_URL的含义相同。
9.STATICFILES_DIRS
和TEMPLATE_DIRS的含义差不多,就是除了各个app的static目录以外还需要管理的静态文件设置,比如项目的公共文件差不多。
10.AUTH_USER_MODEL
自从django 1.5之后, 用户可以自定义User model了, 如果需要外键使用user model
