This is source for a Ruby on Rails (Rails) web application that acts as a trial platform for preference aggregation using the Davenport algorithm for finding Kemeny orders.
The application was begun at the end of 2010, abandoned, and picked-up again at the end of May, 2019.
- Check out the repository:
git checkout git@github.com:wbreeze/socelect.git - Change to the repository directory:
cd socelect - Install the Ruby programming environment at the level indicated in the
file,
.ruby-version. One way is to use the Ruby environment manager (rbenv). - Run the setup script:
script/setup - Start the Rails server for development:
rails server --environment=development - Visit the locally hosted development site to try the app locally
For testing the queueing and delayed processing in development, use the
command delayed_job --pool=result_state:1 --pool=result_compute:2 start.
The Capistrano deploy for production is set-up to run the same.
The result_state queue should have only one worker, because it is used to serialize the state changes. There can be as many workers as you like on the result_compute queue.
