app:
migrations:数据库操作记录,只修改表结构记录
admin:Djangot为我们提供的后台管理
apps:表示配置当前app
model:ORM,写指定的类 通过命令可以创建数据库结构
tests:单元测试
views:写相关所有业务逻辑代码
创建项目流程:
1.模板的路径settings中templates
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‘, ], }, }, ]
2.配置静态资源目录
STATICFILES_DIRS = ( os.path.join(BASE_DIR, ‘static‘), )
注释:第一种通过绝对路径打开html展示。
第二种通过render会去找到settings中templates中配置的dirs路径下的文件。直接就可以找到html文件
