Hello,

I need a solution for my question - i have 2 models, for example  
person and city. model city will have 3 records every time(for example  
London, Berlin, Madrid). Actually i used belongs\_to, has\_many between  
this models and it’s fine, but all the times it run’s SQL to gel list  
of cities. I want to use only one model person and create some class  
that will contain this 3 records and when i will create a new person i  
can choose from select box a city.

Thanks
