Scusate l’italiano ma sono le 11 e sono già fuso 🙂 …

Devo creare una classe che all’applicazione sembri in tutto e per tutto  
una classe ActiveRecord ma che in realtà è un elenco file di una  
directory, qualche idea??

Pensate basti fare l’overload del metodo find?  
(è in sola lettura cmq gli utnti non possono inserire o editare)

Ora ci guardo grazie 🙂

intanto avevo risolto così :

class PrintLayout  
attr\_accessor :id  
attr\_accessor :value

def primary\_key  
return :id  
end

def find(\*args)  
basedir = “#{RAILS\_ROOT}/app/view/print\_layout”  
contains = Dir.new(“#{basedir}”).entries  
result = Array.new  
contains.each do |file|  
if file != ‘.’ and file != ‘…’ and file != ‘.svn’  
entry = PrintLayout.new  
entry.id = file.gsub(“.html.rb”, “”)  
entry.value = file.gsub(“.html.rb”, “”)  
result \<\< entry  
end  
end  
end

def select\_name  
self.value  
end

end
