TODO:

  - correct the graphite host to localhost
  - if desired, put 'debug: true' in there

This example shows how to setup an environment running Rails 3 under 1.9.2 with a 'rails3' gem set.

∴ rvm update --head
# ((Open a new shell)) or do 'rvm reload'

# If you do not already have the ruby interpreter installed, install it:
∴ rvm install 1.9.2

# Switch to 1.9.2-head and gemset rails31rc, create if it doesn't exist. 
∴ rvm --create use 1.9.2@rails31rc

Key issue - format of entered dates:
date is displayed like:  31/3/2011
date is input like:  31-3-2011

This is works correctly in ruby 1.8 and 1.9
ruby-1.8.7-p302 > Time.parse '31-3-2011' # => Thu Mar 31 00:00:00 -1000 2011 
ruby-1.9.2-p0 > Time.parse('31-3-2011')    # => 2011-03-31 00:00:00 -1000 

Changes in parsing dates for ruby 1.9:
* no longer has difference in parsing dates with dash or forward slash - they are always in euro format

Time.parse('3-31-2011')
Time.parse('31-3-2011')
Time.parse('3/31/2011')
Time.parse('31/3/2011')

The rails check_box form helper inserts a hidden checkbox to handle unchecked check boxes.  This doesn't work when the check box is within an array-like parameter - i.e. project[invoice_attributes][blah].

So - below will append a hidden form field with a value - so it can be handled in your controller or model etc.

for:
<%= check_box_tag("instance[data][blah]") %>

jquery:
  $("#instance_form").submit(function() {
    // insert hidden checkbox with value 0 - so unchecked checkboxes submit a value
