• lookup_store

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
