Building and Running
Once PostgreSQL is installed and running:
sudo -u postgres createuser $LOGNAME
Make the new user (yourself) a superuser. Edit the user name and password (if any) in config/database.yml to agree with the PostgreSQL user you just created.
RVM is strongly recommended. Click here for a brief tutorial.
Install the bundler gem.
gem install bundler
Note: You should not use sudo with the gem install command if you are using RVM.
Install gems with the bundler.
bundle install
The WordNet® data set used by Dubsar is quite static, so there is little point in migrating the data. In some cases, it may be desirable to add a small migration (to add an index, for example). However, when making a major update to the database (each time the data model expands), it makes more sense to re-seed from scratch each time. If you pull and migrate, but find that things aren’t working after a significant change to the database, your best bet is to re-seed from scratch:
rake db:drop rake db:setup
Note rake db:setup is simply a shortcut for:
rake db:create rake db:schema:load rake db:seed
Set up the database.
rake db:create rake db:schema:load
Seed the database.

Note: Seeding the DB takes a number of hours on a decent 64-bit processor. While you’re waiting, you can run the unit tests and generate local documentation.
Run unit tests.
rake test
Generate local HTML documentation in doc/app/index.html:
rake doc:app
Once the database has been seeded, run the server.
rails server
Connect a browser to port 3000.
