hi

I have a problem to store the current locale (language) used by a user .

I have this model that represent the locale:

class LocaleModel \< ActiveRecord::Base  
@@global\_locale = nil

def self.global  
@@global\_locale  
end

def self.global=( locale )  
if locale.is\_a? Locale  
@@global\_locale = locale  
elsif locale.is\_a? String  
locale = LocaleModel.find(:first, :conditions =\> ['short = ? ',  
locale])  
return false if (! locale)  
@@global\_locale = locale  
else  
# empty  
@@global\_locale = nil  
end  
end

def master?  
self.master == true  
end  
end

In my application controller I do :

LocaleModel.global = ‘fr’ if LocaleModel.global == nil

And in some other controller I have an action that is used to change the  
locale:

def change\_locale  
LocaleModel.global = params[:lang]  
end

The problem is that when I change the view or reload the page, the  
locale always resets. How come ?

Thank You

I think you misunderstand what’s a global variable in Ruby/Rails  
It’s not storing data between sessions. Whenever a user requests  
a page, it’s reset.  
You must use the session object to store data between requests

Because classes are reloaded between requests in development mode.
