settings

1、注册app:

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

2、配置数据库

#连接mysql数据库

DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'db_name',
'USER':'root',
'PASSWORD':'xxxxxx',
'HOST':'',  #默认localhost
'PORT':'',  #默认8000
    }
}

ps:
# 由于Django内部连接MySQL时使用的是MySQLdb模块,而python3中还无此模块,所以需要使用pymysql来代替
  
# 如下设置放置的与project同名的配置的 __init__.py文件中
  
import pymysql
pymysql.install_as_MySQLdb() 

3、模版

TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [ os.path.join(BASE_DIR,'templates')],
'APP_DIRS': True,
'OPTIONS': {
'context_processors': [
'django.template.context_processors.debug',
'django.template.context_processors.request',
'django.contrib.auth.context_processors.auth',
'django.contrib.messages.context_processors.messages',
],
},
},
]

4、静态文件

STATIC_URL = '/static/'    #前缀
#STATIC_URL定义了当Django运行时,django应用寻找静态媒体的地址。例如STATIC_URL = '/static/' ,STATIC_URL设置成/static/,我们就可以通过http://127.0.0.1:8000/static/来访问它了

STATICFILES_DIRS = (
        os.path.join(BASE_DIR,'static'),
    )
#STATICFILES_DIRS允许定义新的static目录。像TEMPLATE_DIRS元组一样.STATICFILES_DIRS需要static目录的绝对路径.

5、配置上传文件夹(media)并设置为静态可访问文件夹

#settings

#配置上传文件夹
MEDIA_URL = '/media/'  # 设置媒体文件的相对路径
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')  # 设置媒体文件的绝对路径

STATICFILES_DIRS = (
   os.path.join(BASE_DIR, 'static'),
   os.path.join(BASE_DIR, 'media'),
)

#设置为静态url可访问文件夹
##project.url
from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
    path('admin/', admin.site.urls),
  
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) # 配置media

 

6、语言与时区

LANGUAGE_CODE = 'zh-Hans'#语言 

TIME_ZONE = 'Asia/Shanghai' #时区

7、调试模式

DEBUG = True
#DEBUG=True 时,如果出现 bug 便于我们看见问题所在,但是部署时最好不要让用户看见bug的详情,可能一些不怀好心的人攻击网站,造成不必要的麻烦。
