I''ve been kicking this around for months and I thought I would finally
ask
the list and see if I can get some opinions.
I want a database table that holds configuration options for my system.
Think exmail server address, port, maybe a path for a banner image, things
liike that. The way i''ve implemented it is a single column, each
column is
a value. This maps very nicely to a configuration model.
@config = Config.find(1)
@config.smtp_server = ''smtp.mydomain.com''
....
Noiw, what''s the best way to make this available to the application?
Here
are my options:
1. Get the configuration on every request using a before_filtter
Don''t like this because it always hits the DB, but it is always
current
2. Load it up on application startup by populating this through
environment.rb into a hash..
. fastest method, but then it never gets refreshed until the app is
reloaded.
3. Use before_filter to put the hash in the user''s session. Users need
to
log out to see the changes.
4. Do #2 but update the value of the constant when the data changes,
possibly by using a cache sweeperr observer pattern?
Not sure if I like this or not...
I would love to hear some other options! Please share!

Hmmm, no takers? Just looking for suggested methods that people have used to configure applications. Or is everyone just using a bunch of non-changeable constants in the environment file?

Sorry if a dumb question, but I a dumb in Ruby :) Thanks -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
