1. ALLOWED_HOSTS

DEBUG = True

ALLOWED_HOSTS = []

默认为一个空列表，表明此Django网站能够能够提供的主机/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

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'app01',
]

View Code

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 是建立应用app的名字，若是项目建立了app则必需要添加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. 举例来讲:"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, 并没有其余操做.

7.STATIC_ROOT

运行上边提到的命令：python manage.py collectstatic 以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，不能想固然的觉得这个目录和MEDIA_ROOT的做用是相同的，不然在开发环境的时候可能一直没法找到静态文件。

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的含义差很少，就是除了各个app的static目录之外还须要管理的静态文件设置，好比项目的公共文件差很少。

10.AUTH_USER_MODEL

自从django 1.5以后, 用户能够自定义User model了, 若是须要外键使用user model
