Hello,
How to share an Hash between all objects (model, controller ect ...)
=> I did a static Hash in my model where a static method fill it
basically, this is the code
class Person < ActiveModel
@@anHash.new
def Person.anHelperMethod(aKey)
if anHash.size==0
... load the hash, some SQL to fill the Hash
end
return anHash[aKey]
end
=> The problem,: it always reload the Hash ! as it was a local variable
.... I don''t understand since it has the good behavior in the console
env ....
thanks for help

Rails models don''t maintain state btw http requests. As Ezra said, put data that needs to be shared across the app in a constant. - Derek On 6/18/06, Arnaud Garcia <arnaud.garcia@sim.hcuge.ch> wrote:> Ezra Zygmuntowicz a ?crit : > > > > > On Jun 18, 2006, at 9:18 AM, Arnaud Garcia wrote: > > > >> Hello, > >> > >> How to share an Hash between all objects (model, controller ect ...) > >> => I did a static Hash in my model where a static method fill it > >> > >> basically, this is the code > >> > >> class Person < ActiveModel > >> @@anHash.new > >> > >> def Person.anHelperMethod(aKey) > >> if anHash.size==0 > >> ... load the hash, some SQL to fill the Hash > >> end > >> return anHash[aKey] > >> end > >> > >> => The problem,: it always reload the Hash ! as it was a local > >> variable ....
