Hi, all  
I’ve trying to look for answers for my problem but so far couldn’t  
find one, hopefully someone can tell me what to do. In my application,  
I  
have to let user can create new table, and they can add or  
delete columns. The tables they created, I can’t do things that RoR  
usually  
can do, like ( Table.find\_by\_id ), because they are not modeled. Is  
there any  
way that I can setup model for a table that user created on fly?  
Thanks for your help!

The code I used to create table is like this:  
ActiveRecord::Base.connection.create\_table :table\_name do |t|  
t.column :name, :string  
end
