# Simple PyYAML constructor for handling Ruby Flash Hash
# Not perfect or graceful - just takes the Ruby Flash object
# and the Set object inside of it, and nullifies them.
# This could be expanded to handled different tags.

# If you wanted to maintain the Ruby objects across requests,
# or use convert a Ruby object to a Python object, you'll
# need something a little more complex, but this should get
# you started.

Setup RVM/Ruby, Nginx/Passenger, and Rails in minutes on vanilla CentOS (5 or 6)

July 1, 2012

Based on articles at http://articles.slicehost.com/centos

This gist only covers the steps that are necessary to get a Rails app running quickly via RVM, nginx and Passenger. It disregards security in many cases (such as RVM & iptables)! Go through the articles above for more on that.

Please note that I wrote this after I had already got it all working, so I apologize if

# This is a modified versions of Rails' built-in `has_secure_password`
# It allows you to do the same thing to any attribute.
# Useful for legacy databases, credit card information, addresses, etc.

# Use it pretty much the same way you would use has_secure_password
# You can also use any name for the digest column, 
# just pass in an :encrypted_attribute option:
#
#    has_secure_attribute :credit_card_number, encrypted_attribute: :ccn_hash

July 13, 2012

I recently had some trouble trying to figure out how to do a simple gsub to the innner_html of a Nokogiri node. My problem was that I was trying something like this:

# Does not work!
document.at_css('p.content').inner_html.gsub!(/\n/, "<br />")
