method

lookup_store

lookup_store(*store_option)
public

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(:drb_store)
  # => returns a new ActiveSupport::Cache::DRbStore 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

Creating additional cache stores

LacKac ยท Sep 3, 20081 thank

This method can be used to create additional cache stores for your application:

# creates a new Memory Store
mem_store = ActiveSupport::Cache.lookup_store
# creates a new MemCache Store
mem_cache_store = ActiveSupport::Cache.lookup_store :mem_cache_store, 'localhost:11212', :namespace => 'other_stuff'

The method takes the same arguments as the +cache_store+ config. For more information about that go to ActionController::Caching.
