Here's a quick example of using Ruby ActiveRecord outside of Rails. In this case I'm saving a new record to an
employees table in a MySQL database.
require "rubygems" require_gem "activerecord" ActiveRecord::Base.establish_connection ( :adapter => "mysql", :host => "localhost", :username => "root", :database => "HumanResources") class Employee < ActiveRecord::Base end employee = Employee.new employee.first_name = "Fred" employee.last_name = "Flinstone" employee.save
In this case I'm connecting to a local MySQL database with a username of "root" and no password (admittedly not at all secure).
I already had Rails installed, so getting this code to work was just a matter of writing this script, but if you don't have ActiveRecord installed, you can install it like this:
gem install activerecord
A lot of times I write Ruby code that has nothing to do with web pages and Rails, and it's nice to be able to use ActiveRecord without all the other Rails goo.
