1.查看django版本

python -m django --version

2.When to use include()

You should always use `include()` when you include other URL patterns. `admin.site.urls` is the only exception to this.

3. django中的路由机制是由urls.py完成的

4. settings.py

   • If you set DEBUG to False, you also need to properly set the ALLOWED_HOSTSsetting.

   • 修改配置文件名称需要同步修改wsgi中的DJANGO_SETTINGS_MODULE

5. Default settings

   1. A Django settings file doesn’t have to define any settings if it doesn’t need to. Each setting has a sensible default value. These defaults live in the module django/conf/global_settings.py.

   2. Here’s the algorithm Django uses in compiling settings:

      1. Load settings from global_settings.py.

      2. Load settings from the specified settings file, overriding the global settings as necessary.

   3. Note that a settings file should not import from global_settings, because that’s redundan
