Hi everybody,
I had generated some migrations files such as
“20080719111013_create_countries.rb” for “countries” table :
class CreateCountries < ActiveRecord::Migration
def self.up
create_table :countries, :force => true do |t|
t.string :name, :null => false, :limit => 80
end
end
def self.down
drop_table :countries
end
end
And now I would like to generate a new file migration for
“arts_countries” table. But I don’t know how to write the nice command
with the right convention because this table is composed by arts and
countries tables (so there isn’t any model)…
Thanks for every ideas.
