trytond.cache.Cache(name[, size_limit[, context]])¶The class is used to cache values between server requests. The name should
be unique and it’s used to identify the cache. We usually use
<class_name>.<content_name> to make it unique. The size_limit field can
be used to limit the number of values cached and the context parameter
is used to indicate if the cache depends on the user context and is true
by default.
The cache is cleaned on Transaction starts and resets on
Transaction commit or rollback.
Warning
As there is no deepcopy of the values cached, they must never be mutated after being set in or retrieved from the cache.
trytond.cache.get(key[, default])¶Retrieve the value of the key in the cache. If a default is specified it will be returned when the key is missing otherwise it will return None.
trytond.cache.set(key, value)¶Sets the value of the key in the cache.
trytond.cache.clear()¶Clears all the keys in the cache.
trytond.cache.clean(dbname)¶Clean the cache for database dbname
trytond.cache.reset(dbname, name)¶Reset the name cache for database dbname
trytond.cache.resets(dbname)¶Resets all the caches stored for database dbname
trytond.cache.drop(dbname)¶Drops all the caches for database dbname
Note
By default Tryton uses a MemoryCache, but this behaviour can be overridden by setting a fully qualified name of an alternative class defined in the configuration class of the cache section.
