Maybe one of these days I’ll actually complete a rails app. Maybe it will be this one. Maybe not. But I hate doing anything of substance and not blogging about it. I like to go back and read what I did because I don’t do rails stuff enough to be efficient yet.
In any case, my current project is an NFL survivor pool. Pick one team each week. If they win, you survive. If they lose, you’re out. Pretty simple.
I had Ruby 1.8.6 on my Windows 7 machine and Rails 2.3.8. I wrote a good deal of the app, but for some reason I couldn’t push it up to heroku. I decided to upgrade to Ruby 1.9.2 and Rails 3.1. I installed RailsInstaller 2.0 and it was a disaster. I would try to execute commands from the command line and it was clearly looking in the old 1.8.6 directory and couldn’t find them. I’ll bet it’s not really that hard to have multiple ruby versions, but honestly I don’t care to learn. I wiped out everything; uninstall RailsInstaller, delete Ruby directories, delete Git directories. Then I reinstalled RailsInstaller and things seemed to be working better.
I executed ruby -v and got 1.9.2. Good. I executed rails -v and got “file not found”. Then I did
gem install rails
and
gem install heroku
and they installed without incident. Now rails -v returned 3.1. Good. Next, I attempted to run my app locally. It told me I needed to install Rails 2.3.8 when I executed script/server. I didn’t want to use 2.3.8, so I commented out the RAILS_GEM_VERSION line in config/environment.rb. It was set to 2.3.8 and commenting it out should force it use the latest version of Rails. There’s probably a crapload of code in the app that won’t execute using Rails 3. I don’t know and I’m not that interested to find out. So I opted to start from scratch in Rails 3. That sounds like a big cop-out and it is. But the code will be far less crappy, as code always is when you write it the second time. So I
rails new dkusr2
to make a new app called dksur2. I like to use nifty-generators, so I added
gem 'nifty-generators', :group => :development
to my Gemfile and, back at the command line, ran
bundle install
It gave me a bunch of “Using” statements, which I think means it’s already installed, and one “Installing nifty-generators (0.4.6)” statement, which seems to be a good sign.
The next step was to get the empty app on git.

Wow, something worked as I expected it. Next I created a new heroku app.
dick@DICK-HPELITE /c/sites/dksur2 (master)
$ heroku create
Creating evening-snow-8011....... done, stack is bamboo-mri-1.9.2
http://evening-snow-8011.heroku.com/ | git@heroku.com:evening-snow-8011.git
Git remote heroku added
dick@DICK-HPELITE /c/sites/dksur2 (master)
$ git push heroku master
Enter passphrase for key '/c/Users/dick/.ssh/id_rsa':

and a whole bunch of other lines. I went to http://evening-snow-8011.heroku.com/ and got the always heart-warming Welcome Aboard message that means I didn’t screw anything up.
My next step will be to watch Authentication from Scratch and Authentication in Rails 3.1 so I can make my User model and controllers and such. From there, I expect the app will generally look like:
Team
:name, :string
has_many :picks
has_many :users, :through => picks
Game
:start, :datetime
:weekno, :integer
:away_id, :integer
:home_id, :integer
:awayscore, :integer
:homescore, :integer
has_one :away, from team on away_id = id
has_one :home, from team on home_id = id
has_many :picks
Pick
:user_id, :integer
:team_id, :integer
:game_id, :integer
belongs_to user, team, game
