Rails - Oct 2007 - Custom helpers for list of options?

Hi all,

I have a model that "belongs_to" many other models, many of those
models are just list of names, like country, state, city, profession
... I read about the country_select helper.

Is better to have all those tables or use custom helpers? what the rails way?

Thanks.

For example :  http://pastie.caboo.se/104092

# = Schema
# country_id       integer
# city_id          integer
# state_id         integer
# profession_id    integer
# category_id      integer
# ......

class User < ActiveRecord::Base
  belongs_to :country, :city, :state
  belongs_to :profession, :category, :subcategory
end

 ===========  VS

# = Schema
# country    :string
# city       :string
# state      :string
# profession :string
# category   :string
# ......

class User < ActiveRecord::Base
end

class ApplicationHelper
  def city_select (...)
  end
  # ....
  # ....
end

I use tables and then just have helpers that build the arrays for
the select_options for the view.

For example, I have a table for languages and I have this in my
helper:

  def language_options
    Language.find(:all, :order => "language").collect {|l| [
l.language, l.id ]}
  end

Then from my view:

<%= select ''document'', ''language_id'',
language_options  %>

Hope this helps.
