FWIW--you can use AR in a straight ruby program. Frx--something like this
should work I think:
require "rubygems"
require "activerecord"
require "sqlite3"
ActiveRecord::Base.establish_connection(:adapter => 'sqlite', :database =>
'~/my_db.db')
c = ::ActiveRecord::Base.connection
unless c.tables.member?("features")
c.create_table(:features) do |t|
t.column :feature, :string
t.column :category, :string
t.column :count, :integer
end
c.add_index(:features, [:category, :feature], :unique => true)
end
class Feature < ActiveRecord::Base
end
f = Feature.new(:feature => "bibbity", :category => "bobbity", :count => 1)
f.save!
puts("finished!")

Yeah I've definitely considered this... let's call this "Plan B". :)
This is because I would love to have access to all the CRUD/easy persistence
provided by ActiveRecord, while keeping open sockets.
Anyway I'm running into a problem when I try to add class instance variables to
a class that inherits from ActiveRecord. I've tried the method outlined here:
http://74.125.93.132/search?q=cache:8FvmwfP_gDwJ:www.continuousthinking.com/2006/11/17/ruby-class-variable-or-class-instance-variables+ruby-class-variable-or-class-instance-variables&cd=5&hl=en&ct=clnk
(linked through google's cache since the site is down). I got the following
error:
You have a nil object when you didn't expect it!
The error occurred while evaluating nil.columns
Same error when I tried to define the class instance vars using
:class_inheritable_accessor.
Perhaps it's unsupported to add class inheritable attributes to a descendent
ActiveRecord class? I also have found very little talk of
class_inheritable_accessor, so perhaps this is no longer maintained? I would
really appreciate some pointers re:class instance variables in rails...
Thanks,
Steve
