# 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

Replacing tags inside of a Nokogiri Node

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 />")

Accidental Discovery: Interpolation shorthand in Ruby

July 19, 2012

I type in Textmate all day long. One of things its Ruby bundle does is auto-complete the string interpolation syntax for you. If you're inside of double-quotes (or a few other cases where string interpolation is possible), and you hit the # (hash) key, it writes #{} and places your cursor between the curly-brackets.

So, sometimes when I'm testing things in IRB, I forget that it doesn't auto-complete things like Textmate does. The result? Accidentally discovering a shorthand for string interpolation:

@name = "World"
puts "Hello #@name."

Rails: Synchronizing your development database with your production database using Rake tasks

July 30, 2012

If you run an active website with lots of new content every day, it's often helpful to keep your local database up-to-date with your production database, so when you're working on the application locally you're working with fresh content.

Here are a couple rake tasks that you can copy-and-paste into your local Rails application which will make this syncing process a one-step process.

Making Django and Rails play nice: Part 2 (part 2)

July 1, 2012

A few months ago, former KPCC developer Eric Richardson posted a fantastic solution to a seemingly simple problem: How do you share sessions between a Rails application and a Django application?

The issue: Ruby and Python serialize objects using different libraries (Marshal and Pickle, respectively).
