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.
Zhang''

Those habtm tables really aren''t supposed to be modeled on the Ruby side. There''s no such thing as "an ArtsCountries". David -- Rails training from David A.

But given I don''t know what Arts we''re talking about, I can''t suggest one. In my experience, most things that start off being a has_and_belongs_to_many end up becoming a has_many :through, and as such, already having a well named join in beneficial. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I was referring specifically to habtm tables, which should not be modeled. David -- Rails training from David A.
