出现Could not find table 'products'的错误

Question

请高手帮看看这个问题，脱离Rails使用ActiveRecord出现Could not find table 'products'的错误

代码如下：
require 'rubygems'
require 'active_record'

ActiveRecord::Base.establish_connection(
:adapter => "sqlite3" ,
:database => "db/development.sqlites3"
)

class Product < ActiveRecord::Base
end

Answer 1

我正好做了类似的事情，给你参考：require&nbsp;'rubygems'require&nbsp;'active_record'$conn_db&nbsp;=&nbsp;{&nbsp; :adapter&nbsp;=>&nbsp;"mysql2",&nbsp;&nbsp; :host&nbsp;=>&nbsp;"192.168.3.199",&nbsp;&nbsp; :database&nbsp;=>&nbsp;"aaa_db", :username&nbsp;=>&nbsp;"root", :password&nbsp;=>&nbsp;"pppppp", :pool&nbsp;=>&nbsp;5}&nbsp; class&nbsp;MyTable&nbsp;<&nbsp;ActiveRecord::Base establish_connection&nbsp;$conn_db; end ....&nbsp;[其他ruby代码]
