BaseCache.get_or_set() returns False if the key was set in cache between the first .get() and .add(). The reason for using .add() instead of .set() in there is a "big race condition" as stated in #12982. However, it is very unlikely that the caller will pass a default...

filter返回值是一个新的 QuerySet 对象,然后可以对 QuerySet 在进行查询返回新的 QuerySet 对象,支持链式操作,QuerySet 一个集合对象,可使用迭代或者遍历,切片等,但是不等于 list 类型(使用一定要注意)。 3) 异常 get只有一条记录返回的时候才正常,也就说明 get 的查询字段必须是主键或者唯一约束的字段。当返回...

Cacheops also provides get/set primitives for simple cache: from cacheops import cache cache.set(cache_key, data, timeout=None) cache.get(cache_key) cache.delete(cache_key) cache.get will raise CacheMiss if nothing is stored for given key: from cacheops import cache, CacheMiss try: result...
