FlexiRecord is a ruby library providing object oriented access to databases (object-relational mapping). Each table is represented by a class, each row of that table is represented by an object of that class. This library is especially aimed to properly support database transactions. By now only PostgreSQL (version 8.2 or higher!) is supported as a backend.

Please mind that this is a beta release.

To use FlexiRecord, you have to first create a new ConnectionPool with ConnectionPool.new. If all tables are stored on the same database, you can directly assign the ConnectionPool to the BaseRecord class, by calling:

FlexiRecord::BaseRecord.connection_pool = FlexiRecord::ConnectionPool.new(…)

You should also create sub-classes of BaseRecord, representing the tables of your database.

There is a demonstration of the usage of this library in the flexirecord-demo.rb file (module FlexiRecordDemo).
