create_table with unique combo
I need to create a table replacing default integer id with a string id
and making a combo of (id and version) unique primary key. Here is
what I''ve got so far.
class CreateCatalogs < ActiveRecord::Migration
def self.up
create_table :catalogs, :id => false do |t|
t.string :id, :limit => 20, :null => false
t.string :version, :default => ''01''
t.timestamps
end
end
def self.down
drop_table :catalogs
end
end...
