Description:

The geocodable migration generator creates a migration which you can use to generate two tables:

  geocodes - Contains the latitude and longitude coordinates, with the address they refer to.
  geocodings - The polymorphic join table.

Example:

rails generate acts_as_geocodable

With 4 existing migrations, this will create an AddGeocodableTables migration in the
file db/migrate/5_add_geocodable_tables.rb
