Best practice on global settings

rubyonrails-talk

I have a Rails site that needs to have global access to some settings which I would like to set in a separate file, e.g. the location of a companion server. I have done this in a couple of ways but none of them seems to be very elegant or Ruby-like. Does anyone have any input on the best practice of dealing with data of this kind.

Thanks in advance

Thank you for the suggestion. I tried environment.rb but I think it is not a nice solution because of the discrepancy in data types. The settings in environment.rb is mostly directives on hov the server should act and updates require restarting the server. What I would like is a separate file for settings regarding the application itself, not the server on which it is run. A trivial difference perhaps, but I think it is an important one. I don't like setting the preferred graphics format for user uploads in the same place as where I set e.g. which parts of Rails to use. I will use this solution if there are no good alternatives but I have a feeling there are.

I create a module in lib folder with some text constants.

Hi

This sounds interesting. Could you give a more detailed example. Do you use module variables or module instance variables, where do you include it and so on. Do you know of any articles on this subject. I would be very thankful for the assistance.

Kindest regards

some time ago, somebody suggested searching ageilwebdev.com on "settings", it works:

lib\somefile.rb

module MySettingsContainer SOMETEXT = "SOME TEXT VALUE" end

controller

requere "somefile.rb" (or require lib/somefile.rb)

class AAA < AplicationController include MySettingsContainer # i think it's not needed

def index @result = MySettingsContainer::SOMETEXT end

end

Many thanks, I will try that.

How about:

- Use the app_config plugin to get a nice syntax - Add a line in config/environment.rb to 'require application' - Put the app_config stuff in config/application.rb

I think that'll work, unless 'require application' ends up loading one of the other application.rb files due to load path order, in which case you should be able to do something like require "#{config_dir}/application".
