Rails - May 2006 - Best place for storing configuration information?

Hi all,

Where do you store your non-Rails-specific configuration info?  For
instance, I want to be able to login to LDAP as a particular admin
user.  I don''t want the u/p combo in any of the models...does it go in
environment.rb?  database.yml?  Set a constant in a lib file?

When you''ve got it in a good location, how do you access it?

Thanks!

Sean

This is what I''ve done...

% cat config/site.yml
defaults: &defaults
   memcache_servers    : [''127.0.0.1:11211'',
''127.0.0.1:11212'']
   use_static_banners  : true

development:
   <<: *defaults
   use_static_banners  : true


test:
   use_static_banners  : false
   <<: *defaults

production:
   use_static_banners  : false
   <<: *defaults


Then, in environment.rb do:

site_yaml = YAML::load_file("#{RAILS_ROOT}/config/site.yml")
...
... = site_yaml[RAILS_ENV][''use_static_banners'']
... = site_yaml[RAILS_ENV][''memcache_servers'']
...

I used the Settings plugin 
http://wiki.rubyonrails.com/rails/pages/SettingsPlugin

works very well for tracking global variables, and you can easily set 
different values for different environments, since they are in different 
databases.

Sean,


I added this code at the bottom of my environment.rb file:

class FooConfig
     @@property = {
         :ldap_authenticator => {
                   :port         => 389,
                   :host         => ''yahoo.google.be'',
                   :sac_dn       => ''???'',
                   :sac_passw    => ''???'',
                   :base_dn      => ''???''
                   }
     }
     cattr_accessor :property
     def self.method_missing(method, *arguments)
         FooConfig.property[method.to_sym]
     end
end


To read the values, you''d just write

         port = FooConfig.ldap_authenticator[:port]
         host = FooConfig.ldap_authenticator[:host]


though I couldn''t resist Rubyfying it a little further:

#add this in the heavy LDAP settings'' user code:

     # implements: host(), port(), sac_dn(), sac_passw() and base_dn()
     def self.method_missing(method, *arguments)
         FooConfig.ldap_authenticator[method.to_sym]
     end

, so you can just type
     port = port()
     host = host()
