ActiveRecordLite

ActiveRecordLite is an object-relational mapping system inspired by ActiveRecord. Uses Ruby's metaprogramming capabilities to implement its core functionality.

Current Features

• SQLObject::find(id) returns a SQLObject with attributes matching the database row having the corresponding id
• SQLObject#insert creates new row in the database with the SQLObject's attributes and assigns an id
• SQLObject#update maps current attribute values over previous column values in the database on the row with the corresponding id
• SQLObject#save inserts or updates SQLObject based on id.nil?
• SQLObject#where(params) forms and executes SQL query based on params; returns an array of SQLObjects
• SQLObject#belongs_to(name, options) defines a method, name, that returns a SQLObject whose #model_name and :primary_key value correspond to the :class_name option and :foreign_key value of the association
• SQLObject#has_many(name, options) is the inverse of #belongs_to; defines a method, name that returns an array of SQLObjects with appropriate #model_names and :primary_key values
• SQLObject#has_one_through(name, through_name, source_name) defines a relationship between two SQLObjects through two #belongs_to relationships. Defines a method, name, that returns a SQLObject whose #model_name corresponds to the source_name
