Rather than a global variable, you probably want to put something in the ApplicationController.

Either:

before_filter initialize_support

def initialize_support
      @support = Support.new(:id => 1)
end

Or:

helper_method support_form

def support_form
      @support_form ||= Support.new(:id => 1)
end
