settings

一、註冊app：

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

二、配置數據庫

#鏈接mysql數據庫

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

ps：
# 因爲Django內部鏈接MySQL時使用的是MySQLdb模塊，而python3中還無此模塊，因此須要使用pymysql來代替
  
# 以下設置放置的與project同名的配置的 __init__.py文件中
  
import pymysql
pymysql.install_as_MySQLdb()　

三、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',
            ],
        },
    },
]

四、靜態文件

STATIC_URL = '/static/'    #前綴
#STATIC_URL定義了當Django運行時，django應用尋找靜態媒體的地址。例如STATIC_URL = '/static/' ，STATIC_URL設置成/static/,咱們就能夠經過http://127.0.0.1:8000/static/來訪問它了

STATICFILES_DIRS = (
        os.path.join(BASE_DIR,'static'),
    )
#STATICFILES_DIRS容許定義新的static目錄。像TEMPLATE_DIRS元組同樣.STATICFILES_DIRS須要static目錄的絕對路徑.

五、配置上傳文件夾（media）並設置爲靜態可訪問文件夾

#settings

#配置上傳文件夾

MEDIA_URL = '/media/'  # 設置媒體文件的相對路徑
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')  # 設置媒體文件的絕對路徑

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

#設置爲靜態url可訪問文件夾
##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

 

六、語言與時區

LANGUAGE_CODE = 'zh-Hans'#語言 

TIME_ZONE = 'Asia/Shanghai' #時區

七、調試模式

DEBUG = True
#DEBUG＝True 時，若是出現 bug 便於咱們看見問題所在，可是部署時最好不要讓用戶看見bug的詳情，可能一些不懷好心的人攻擊網站，形成沒必要要的麻煩。
