Class Method Details

.extend_active_record_scope ⇒ Object

Will automatically add the #using_shard method to all ActiveRecord scopes (including has_many and habtm relations).

Despite the fact that the #using_shard method will exist for all scopes, it will only have effect when loading/saving models that include the Rails::Sharding::Shardable module
