Ruby on Rails: How to load session objects into console

This took a little bit of poking around, so I decided to post it here.

Basically I was tracking down a bug, which resulted in a corrupt object (cart) in the web session. So I thought, it would be nice to play with this object in the console to see what's up... But how do I get it in there?

There may be a more elegant way to do this but here is how I got it to load:
  1. Look in tmp/sessions and find the most recent file (ls -alrt on UNIX). Let's say the file is called 'tmp/sessions/ruby_sess.8eb9614a7e4e1e3b'
  2. Open console and type:
    >> session = Marshal.load(File.open('tmp/sessions/ruby_sess.8eb9614a7e4e1e3b'))
    => {"hash"=>{:cart=...
    >> cart = session["hash"][:cart]
    ....
    
    In this case I was trying to access a cart object in the session, which was placed in the session with:session[:cart] = Cart.new
That's it!

What if you store the session in the DB?

AR Session Store:

Find the session id from the cookie and then Session.find_by_id(:my_session_id)

CGI::Session::ActiveRecordStore::Session.find_by_session_id(session_id)

Car or Auto Make-Model-Year Database : For Breakfast

Make Model What?If you like me were tasked with loading a database of recent car makes/models/years, you would start by looking on the web and seeing if someone else just has it out there, readily available, hopefully for free, but perhaps for a tiny nominal fee.?If only it was that simple... I looked and looked, and couldn't find anything that would fit the above requirements. So I thought, who would know about US car models better than Kelly Blue Book? So I went on their site, and sure enough they have a javascript file that lists all known to them makes and models of used cars. Since the file is public, I figured it's not really "evil" if I scrape and parse it for my own benefit. Disagree? Have a better source? Then leave a comment.Anyway, to cut the long story short, I'm hoping to save a day or so to someone else who may, like me, be looking for this information. The ruby module shown below retrieves and parses the javascript from KBB site into a Ruby da…

On Ruby on Rails with PostgreSQL, and Acts as Paranoid

Back a few years ago I was researching differences between PostgreSQL and MySQL databases, and chose PostgreSQL because at the time it supported foreign key constraints and many other fantastic SQL extensions that make developer's life a lot easier. Today I am sure MySQL is just as functional as PostgreSQL, and it does appear to be a more popular choice as the Rails DB than MySQL. I still prefer PostgreSQL, it just feels more natural to me coming out of Oracle background, so I am probably biased (who isn't?) Anyway, in the last year and a half or so, I've been writing Rails apps that use PG-based databases and found a few random tricks I'd love to share here. Opinions differ here, but just like accountants like the ancient double entry accounting system, I personally prefer a double validation system - where Rails validates my objects before/after updates, but the database double checks this using proper constraints. Rail's validation system is very robust and ext…

Ruby on Rails Hosting: From HostingRails to RailsMachine in a shake of a tail

Rails hosting is a hot subject, and with everyone asking everyone else about their experience, I thought its only fair to share my own experience, even though it is relatively limited. Introduction I started with a shared "professional" hosting plan from HostingRails. It was around $30/month, and included non-root SSH access to a shared server, and additional 150Mb of RAM for total of 200Mb (although that's actually quite misleading, see below). I stayed on this plan for about 3-4 months, and then decided to switch to a virtual hosting plan from RailsMachine - their single server plan, for about $100/month (that includes dedicated 384Mb of RAM and a root access to my virtual server). This post describes the reasons behind switching, and compares pros and cons of each hosting plan. Our needs included the following setup: One application running in two instances (one production, and one test) Two-mongrel instances per application (so total of 4 mongrels) Capistrano base…
