UNIONs in ActiveRecord! Adds proper union and union_all methods to ActiveRecord::Relation.

ActiveRecord provides validations on app level but it won't guarantee the consistent. In some cases, like `validates_uniqueness_of` it executes additional SQL query to the database and that is not very efficient. The main goal of the gem is to provide compatibility between database constraints and ActiveRecord validations with better performance and consistency.

MetaWhere offers the ability to call any Arel predicate methods (with a few convenient aliases) on your Model's attributes instead of the ones normally offered by ActiveRecord's hash parameters.
