counter_culture provides turbo-charged counter caches that are kept up-to-date not just on create and destroy, that support multiple levels of indirection through relationships, allow dynamic column names and that avoid deadlocks by updating in the after_commit callback.

Use this module to defer actions to the after-commit hook. This is useful if you want to trigger actions in after_create, after_destroy and after_update callbacks but want to execute them outside of the transaction (for example, to avoid deadlocks).
