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 …

If you want to share a hash between all of your app then you should

put it in environment.rb like so:

MYHASH = {:foo => ‘bar’, :baz => 'qux}.freeze

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.

In development mode your ActiveRecord model classes are reloaded on each
request. In production mode they are not.
