Question

Looking to create a business directory that can be sorted first by state then city (similar to Craigslist).

Should I create a state model and city model separately or created a locations model with both state and city as separate columns in the locations table?

Answer 1

I would go with 2 columns: state and city.

In order to go something like:

Collection.order('state ASC') or
Collection.order('city ASC')

Depends after on how complex you want the thing to be.
