ActiveRecord basic scopes.

You can use basic-scopes just as normal ActiveRecord methods.

• except_id(id) - all records without matching ID field
• filter_id(id) - all records with matching ID field
• except_ids(ids) - all records without matching ID field
• filter_ids(ids) - all records with matching ID field
• filter_updated_since(time) - all records that have UPDATED_AT field greater than time
• filter_updated_till(time) - all records that have UPDATED_AT field lesser than time
• filter_created_since(time) - all records that have CREATED_AT field greater than time
• filter_created_till(time) - all records that have CREATED_AT field lesser than time

NOTE: ids param is an Array of IDs; id is single value

• by_id - order by ID descending
• by_id_reversed - order by ID ascending
• by_created_at - order by CREATED_AT descending
• by_created_at_reversed - order by CREATED_AT ascending
• by_updated_at - order by UPDATED_AT descending
• by_updated_at_reversed - order by UPDATED_AT ascending

Account.except_id(1) - All Accounts except ID == 1. User.filter_updated_since(1.day).by_updated_at - All Users updated in the last one day, ordered by time
