ref libs:

  • 中文文档: http://django-redis-chs.readthedocs.io/zh_CN/latest/
  • 使用 redis 替换 django 默认 cache backend
• https://github.com/BertrandBordage/django-cachalot
  • 对 SQL 层面作缓存

redis buff:

• https://github.com/redis/hiredis-py

• 同时安装 redis-py 和 hiredis, 会自动提高性能.

整站缓存配置:

• https://docs.djangoproject.com/en/2.0/topics/cache/#the-per-site-cache

• 两个中间件, 必须一个最前, 一个最后.

• 开启整站缓存模式.

MIDDLEWARE = [
    'django.middleware.cache.UpdateCacheMiddleware',    # 所有中间件之前

    # ...
    'django.middleware.common.CommonMiddleware',
    # ...

    'django.middleware.cache.FetchFromCacheMiddleware',  # 所有中间件之后
]

缓存: 单个view 页面

• https://docs.djangoproject.com/en/2.0/topics/cache/#the-per-view-cache
• 缓存装饰器, 对 view 作装饰.

根据 URL 缓存页面:
