Rails - Jan 2006 - Parse request URL.

Hello all.

Due to the mistakes of the company before I joined ;) I am stuck with a 
multiple database setup. I am planning on parsing the REQUEST_URL to 
decide which controller is being accessed and basing the 
establish_connection on that. Before I go messing around with regexps I 
was wondering if rails has a built in function for parsing URLS. I have 
googled around a bit and seen net/http but I cannot find an API for it.

Thanks

Jeff

The request URL is chopped up by config/routes.rb.  I''d start there.

I found out about require ''URI'' and ended up using that.

class ApplicationController < ActionController::Base
  before_filter :change_database

  def change_database
    path = URI.parse(request.env["REQUEST_URI"]).path
    comp = path.split(''/'')

    if comp[1].downcase == ''sheet''
  	  ActiveRecord::Base.establish_connection(
      :adapter  => "XXX",
      :database => "XXX",
      :host     => "XXX",
      :username => "XXX",
      :password => "XXX"
      )
    elsif comp[1].downcase == ''component''
  	  ActiveRecord::Base.establish_connection(
      :adapter  => "XXX",
      :database => "XXX",
      :host     => "XXX",
      :username => "XXX",
      :password => "XXX"
      )
    end
  end
end

Cheers

there are easier ways to determine the controller...

params[:controller] in a before_filter should do the trick...

heh,

try self.class in a before filter in ApplicationController, its probably 
the best way...
