Herodotus

A lightweight Ruby ORM inspired by ActiveRecords from Ruby on Rails. Herodotus converts tables in Sqlite3 database into Herodotus::SQLObject class

Herodotus can perform core CRUD methods with associations.

Demo

1. $cd into "demo folder"
2. Run demo by $ruby demo.rb

Instructions

1. Create SQLite3 tables with SQL like so:

CREATE TABLE names (
  id INTEGER PRIMARY KEY,
  fname VARCHAR(255) NOT NULL,
  lname VARCHAR(255) NOT NULL,

  FOREIGN KEY(seat_id) REFERENCES name(id)
)

2. Create database with cat '{SQL_FILE_NAME}.sql' | sqlite3 '{DB_FILE_NAME}.db'
3. Open Sqlite3 database with: sqlite3 tables.db
4. Run DBConnection.open('{DB_FILE_NAME}.db')

API

Querying is made easy with core features like:

• ::find
• ::where
