Rails - Aug 2006 - Store common settings in one file?

Hi,

I''m looking for a way to store common settings, such as the 
application_name or email address from value in a file.

I then want to be able to call these settings in my controllers and 
models?

Is there any easy way of doing this? and where would you recommend I 
save the file ?

Thanks
scott

Put the file in the lib directory and then just require it where you
need it. You could also make it a Module which may be loaded for you
and then you can just include it.

lib/application-info.rb

module ApplicationInfo
  attr_reader :application_name, :application_email
  @application_name = "My Cool App"
  @application_email = "cool-kaBaBF+qkVv3oGB3hsPCZA@public.gmane.org"
end

class SomethingController < AC::Base
    include ApplicationInfo

    # now your actions and views have access to
    # @application_name and @application_email

end

I just stick my common settings into environment.rb, such as:

SUPPORT_EMAIL = "support@mydomain.com"

then I can use "mail_to(SUPPORT_EMAIL)" inside my app

Hi Scott,

I would go for something much simpler, in environnment.rb:
CONFIG = {
  :email => ''foo@bar.com'',
}

Then, calling from everywhere in the app: CONFIG[:email]

There are numerous plugins for this. Naively I wrote this code that I put in
/lib. You can get to it from anywhere and it provides a straightforward
array-like interface. E.g.,

Options[:email_from] = ''theboss@mydomain.com''
Options[:smtp_server] = ''smtp.mydomain.com''

HTH


# Provide a container for global option storage
# Both getter/setter and [] access methods are
# provided.

class Options
  @@option_hash = {}
  
  def self.set(option_name, value)
    option_name = option_name.to_s
    @@option_hash[option_name] = value
  end
  
  def self.get(option_name)
    option_name = option_name.to_s
    @@option_hash[option_name]
  end
  
  def self.[]=(option_name, value)
    option_name = option_name.to_s
    self.set(option_name, value)
  end
  
  def self.[](option_name)
    option_name = option_name.to_s
    self.get(option_name)
  end
  
  def self.has_key?(key)
    key = key.to_s
    @@option_hash.has_key?(key)
  end
  
  def self.key?(key)
    self.has_key?(key)
  end
end
