ruby on rails - Where to hold important lists -


my app has numerous lists of options that, example, govern stage project @ - these options users choose select list. have many of these , i'm running organization problem, namely define these in 1 place system stays dry.

i'm wary of generating lots of polymorphic tables in interests of normalization, complicate code quite bit without adding in way of real value.

can give me example of store options 1) options possible field, , 2) available in form system-wide?

i use symbolize gem kind of scenario. can store field options strings, perform operations on model values symbols, use i18n labels, , there's set of helpers build selects based on options.

also, code kept clean, since set available options on model itself.

check out:

https://github.com/nofxx/symbolize

here's sample documentation:

class user < activerecord::base   symbolize :gender, :in => [:female, :male], :scopes => true   symbolize :so, :in => {     :linux   => "linux",     :mac     => "mac os x"   }, :scopes => true    # allow blank   symbolize :gui,  :in => [:gnome, :kde, :xfce], :allow_blank => true    # don`t i18n   symbolize :browser, :in => [:firefox, :opera], :i18n => false, :methods => true    # scopes   symbolize :angry, :in => [true, false], :scopes => true    # don`t validate   symbolize :lang, :in => [:ruby, :c, :erlang], :validate => false    # default   symbolize :kind, :in => [:admin, :manager, :user], :default => :admin end
