1.配置静态文件

#STATIC_URL = '/static/'为静态文件别名
    STATIC_URL = '/static/'
    #静态文件地址拼接，后面'static'文件为自己建立的存放静态文件（JS，IMG，CSS）的文件名
    STATICFILES_DIRS = (
        os.path.join(BASE_DIR, 'static'), #主文件下静态文件
        os.path.join(BASE_DIR,"blog","statics"),#项目blog文件下静态文件
    )

2.mysql数据库配置

########在setting原来默认的sqlite
    DATABASES = {
        'default': {
            'ENGINE': 'django.db.backends.sqlite3',
            'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
        }
    }
    ############修改成mysql如下
    DATABASES = {
    
        'default': {
    
            'ENGINE': 'django.db.backends.mysql',
    
            'NAME': 'test',    #你的数据库名称
    
            'USER': 'root',   #你的数据库用户名
    
            'PASSWORD': '19941028', #你的数据库密码
    
            'HOST': '', #你的数据库主机，留空默认为localhost
    
            'PORT': '3306', #你的数据库端口
        }}
    #由于mysql默认引擎为MySQLdb，在__init__.py文件中添加下面代码
    #在python3中须替换为pymysql,可在主配置文件（和项目同名的文件下，不是app配置文件）中增加如下代码
    import pymysql
    pymysql.install_as_MySQLdb()

3.设置打印日志到屏幕

LOGGING = {
        'version': 1,
        'disable_existing_loggers': False,
        'handlers': {
            'console':{
                'level':'DEBUG',
                'class':'logging.StreamHandler',
            },
        },
        'loggers': {
            'django.db.backends': {
                'handlers': ['console'],
                'propagate': True,
                'level':'DEBUG',
            },
        }
    }

4.语言

LANGUAGE_CODE = 'en-us'# 默认
    LANGUAGE_CODE = 'zh-hans'# 改为中文，主要针对admin页面

5.配置模板

TEMPLATE_DIRS = (
            os.path.join(BASE_DIR,'templates'),
        )

6.setting文件默认代码注释

import os
    
    # Build paths inside the project like this: os.path.join(BASE_DIR, ...)
    #向上找两级，获取基地址
    BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
