Which is the best way to create a thin key/value related to some
model? where a field only could insert those values (keys as 0,1) and
where could be showed the values (as Red, Blue) from a drop-list
COLOUR_OPTIONS = {0=>"Red", 1=>"Blue"}
t.string :colour

I will say that I would prefer to just store the actual values ("Red", "Blue", etc.) or if you want to store numeric keys, then create an actual table and setup an association. class Whatever < ActiveRecord::Base belongs_to :colour end class Colour < ActiveRecord::Base has_many :whatevers end HTH, Michael Guterl --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
