arel_extensions
A Ruby gem that extends Arel with shortcuts, fixes, and new ORM mappings for advanced SQL functions across multiple databases.
What is arel_extensions?
Arel Extensions is a Ruby gem that extends the Arel library, which is used by ActiveRecord for building SQL queries. It adds shortcuts, fixes, and new ORM mappings to support advanced SQL functions—like mathematical operations, string manipulations, and date/time handling—across multiple databases. It solves the problem of writing database-specific SQL by providing a pure Ruby syntax for complex queries.
Ruby on Rails developers who need to write complex, database-agnostic SQL queries using ActiveRecord and Arel, especially those working with multiple RDBMS like MySQL, PostgreSQL, or SQL Server.
Developers choose Arel Extensions because it allows them to use advanced SQL features directly in Ruby code without dropping down to raw SQL, ensuring portability across databases and maintaining the elegance of ActiveRecord's query interface.
