# I found a bit of odd rails behavior recently.  Consider the following classes.

class Contact < ActiveRecord::Base
    belongs_to :gallery
end

class Gallery < ActiveRecord::Base
    has_many :contacts
end

Deploying Rails to Linode

Installing Ruby Enterprise Edition, Apache, MySQL, and Passenger for deploying Rails 3.0 applications.

Get a Linode, and set it up with Ubuntu 10.04 LTS so that you have till April 2013 to get updates. Once the Linode is formatted, boot it and continue on.

Set up an 'A' record in your DNS, pointing to the IP of your Linode. I'm using demo.napcs.com here.

Initial setup

# NOTE: Prawn 1.0 now supports images in tables, and it works much better than my mock table below!



# As you may have noticed Prawn does not currently support images in table cells.  
# There is an unofficial fork with initial table image support but it appears that 
# it will be some time before this gets merged into the official branch.
#
# Instead of using an unofficial branch, I found a nice way to do a mock table with 
# image support.  You just need to keep track of your page breaks.
