See ActiveSupport::Cache::Store for documentation.
UNIVERSAL_OPTIONS | = | [:namespace, :compress, :compress_threshold, :expires_in, :race_condition_ttl] | These options mean something to all cache implementations. Individual cache implementations may support additional options. |
Creates a new CacheStore object according to the given options.
If no arguments are passed to this method, then a new ActiveSupport::Cache::MemoryStore object will be returned.
If you pass a Symbol as the first argument, then a corresponding cache store class under the ActiveSupport::Cache namespace will be created. For example:
ActiveSupport::Cache.lookup_store(:memory_store) # => returns a new ActiveSupport::Cache::MemoryStore object ActiveSupport::Cache.lookup_store(:mem_cache_store) # => returns a new ActiveSupport::Cache::MemCacheStore object
Any additional arguments will be passed to the corresponding cache store class‘s constructor:
ActiveSupport::Cache.lookup_store(:file_store, "/tmp/cache") # => same as: ActiveSupport::Cache::FileStore.new("/tmp/cache")
If the first argument is not a Symbol, then it will simply be returned:
ActiveSupport::Cache.lookup_store(MyOwnCacheStore.new) # => returns MyOwnCacheStore.new
