Notable Features

• Standard support for all of the common relationships — This includes belongs_to, has_many, and many_to_many. Pretty much standard these days.

• Top-to-bottom table column aliasing – All references to database columns and tables are made via their aliased names and converted transparently, on the fly.

• Active testing on MySQL and SQLite — All of the Jelly unit tests work 100% correctly on both MySQL, SQLite and PostgresSQL databases.

• A built-in query builder — This features is a near direct port from Kohana's native ORM. I find its usage much simpler than Sprig's.

• Extensible field architecture — All fields in a model are represented by a Field_* class, which can be easily overridden and created for custom needs. Additionally, fields can implement behaviors that let the model know it has special ways of doing things.

• No circular references — Fields are well-designed to prevent the infinite loop problem that sometimes plagues Sprig. It's even possible to have same-table child/parent references out of the box without intermediate models.
