记得不要忘记配置static你所引入的前端样式 还有settings内的数据库配置：
settings:
配置数据库：
DATABASES = {
‘default‘: {
‘ENGINE‘: ‘django.db.backends.mysql‘,
‘NAME‘:‘test‘, # 要连接的数据库，连接前需要创建好
‘USER‘:‘root‘, # 连接数据库的用户名
‘PASSWORD‘:‘zhaoyun‘, # 连接数据库的密码
‘HOST‘:‘127.0.0.1‘, # 连接主机，默认本级
‘PORT‘:3306 # 端口 默认3306
}
}
配置static：
STATICFILES = [
os.path.join(BASE_DIR,‘static‘)
]
