代码如下： require 'rubygems' require 'active_record'
ActiveRecord::Base.establish_connection( :adapter => "sqlite3" , :database => "db/development.sqlites3" )
class Product < ActiveRecord::Base end
人生最曼妙的风景，竟是内心的淡定与从容！
I happened to do something similar, for your reference:
require 'rubygems' require 'active_record' $conn_db = { :adapter => "mysql2", :host => "192.168.3.199", :database => "aaa_db", :username => "root", :password => "pppppp", :pool => 5 } class MyTable < ActiveRecord::Base establish_connection $conn_db; end .... [其他ruby代码]
Are you sure there is this table in the database?
rake db:create rake db:migrate
