问题描述： Python manage.py runserver ，禁用缓存，及时修改反馈到浏览器

解决办法：

使用dummy cache：

Dummy caching (for development)

Finally, Django comes with a “dummy” cache that doesn’t actually cache – it just implements the cache interface without doing anything.

This is useful if you have a production site that uses heavy-duty caching in various places but a development/test environment where you don’t want to cache and don’t want to have to change your code to special-case the latter. To activate dummy caching, set BACKEND like so:

CACHES = {
    'default': {
        'BACKEND': 'django.core.cache.backends.dummy.DummyCache',
    }
}

另外，chrome浏览器也需要设置，F12打开devtools，在network 标签下勾选 禁用缓存！
