djangorestframework不能反映资源的变化

Question

当我做一些后/补丁请求Django的REST的架构基于网络的服务，JSON格式卷曲，我可以看到在一个数据库管理页面上还有变化，但拿一段时间，这一数字到API中反映（GET请求）

预先感谢您。

另外，还要确保你的中间件是在MIDDLEWARE_CLASSES的最后一件事。 按照从Django的源代码文档：

django.middleware.cache.py（Django的1.5版本）

class UpdateCacheMiddleware(object): 
    """ 
    Response-phase cache middleware that updates the cache if the response is 
    cacheable. 

    Must be used as part of the two-part update/fetch cache middleware. 
    UpdateCacheMiddleware must be the first piece of middleware in 
    MIDDLEWARE_CLASSES so that it'll get called last during the response phase. 
    """ 
    # -- snip -- 

class FetchFromCacheMiddleware(object): 
    """ 
    Request-phase cache middleware that fetches a page from the cache. 

    Must be used as part of the two-part update/fetch cache middleware. 
    FetchFromCacheMiddleware must be the last piece of middleware in 
    MIDDLEWARE_CLASSES so that it'll get called last during the request phase. 
    """ 
    # -- snip -- 

class CacheMiddleware(UpdateCacheMiddleware, FetchFromCacheMiddleware): 
    """ 
    Cache middleware that provides basic behavior for many simple sites. 

    Also used as the hook point for the cache decorator, which is generated 
    using the decorator-from-middleware utility. 
    """ 
    # -- snip --
