Where is global Rails configuration?

Hi,

Let's say I wanted to add something to Rails that I would like all applications to use. For example, I would like to add the pluggable parameter parsing using:

ActionController::Base.param_parsers['application/atom+xml'] = Proc.new do |data|   node = REXML::Document.new data   { node.root.name => node.root } end

(got this example from e.g. http://www.linuxjournal.com/article/8968, but it's also in the source code). I would not like this to be related to a specific controller or application - I would like to add it for all applications at once. In this case, it would be for both already existing applications and the ones I create. What is the appropriate place for this (if any)? I know that editing environment.rb is a good place for per-application settings.

Yes, another (relatively simple) way would be to just 'require' the Ruby file with these settings in all applicaitons, but I am just curious if there is some standard way of doing this.

I would say the appropriate place for this would be in a plugin. Doing anything else would mean modifying the Rails core code, which I'm guessing would violate your Rails open source license agreement (unless you're a Rails contributor). Basically, if you modify Rails it won't be Rails anymore.

Rails is kind enough to offer a plug-in architecture where you should be able to do what you want and include it into all or your applications.
