I want to create one creature and write it to the dwemthys.db, and I’m
close. From the example at <http://www.dzone.com/links/rss/
simple_ruby_activerecord_example.html?> I know that the “create” method
is used for this, but somehow it fails when for creatures when it works
for the example.
All code is at http://code.google.com/p/dwemthys/source, but this is
what I’m running into:
thufir@arrakis ~/Desktop/dwemthys $
thufir@arrakis ~/Desktop/dwemthys $ ruby creatures.rb
– create_table(:creatures)
SQL (0.016574) CREATE TABLE creatures (“id” INTEGER PRIMARY KEY NOT
NULL, “life” integer DEFAULT NULL, “strength” integer DEFAULT NULL,
“charisma” integer DEFAULT NULL, “weapon” integer DEFAULT NULL)
→ 0.1334s
creatures.rb:28: undefined method `create’ for Creature:Class
(NoMethodError)
thufir@arrakis ~/Desktop/dwemthys $
thufir@arrakis ~/Desktop/dwemthys $ cat creatures.rb
require ‘active_record’
require ‘ArrayOfCreatures’
require ‘MakeCreature’
require ‘Creature’
include MakeCreature
ActiveRecord::Base.logger = Logger.new(STDERR)
ActiveRecord::Base.colorize_logging = true
ActiveRecord::Base.establish_connection(
:adapter => “sqlite3”,
:dbfile => “dwemthys.db”
)
ActiveRecord::Schema.define do
create_table :creatures do |table|
table.column :life, :integer
table.column :strength, :integer
table.column :charisma, :integer
table.column :weapon, :integer
end
end
creature = Creature.create
thufir@arrakis ~/Desktop/dwemthys $
thufir@arrakis ~/Desktop/dwemthys $ cat Creature.rb
require ‘Math’
class Creature
Creature.extend Math
include Math
attr_accessor :life, :strength, :charisma, :weapon
def initialize ()
@life = 10
@strength = 10
@charisma = 10
@weapon = 10
end
def toString ()
print “class\t\t”
print self.class
print "\nlife\t\t"
print @life
print "\nstrength\t"
print @strength
print "\ncharisma\t"
print @charisma
print "\nweapon\t\t"
print @weapon
print "\n"
end
end
