Events@Penn is a events aggregation website built by the web team at The Daily Pennsylvanian.

Ruby on Rails

This application requires:

  • Ruby 2.4.0
  • Rails 5.1.1

Getting Started

Make sure you have Ruby installed by running ruby -v on the command line. This project requires v2.4.0, so make sure you have at least that version. If the command returns "ruby: command not found", run brew install ruby (see here if you're using anything other than MacOS).

Clone the repo into whichever folder you keep your DP work in.

git clone

Move to the eventsatpenn root folder and run bundle install to install all of the gem dependencies for this project. This may take a minute.

You'll have to specify that you're working in the development environment. To do this, run the following command:

export RAILS_ENV="development"

This will specify to the database to use SQLite, which we use for development, rather than MySQL, which we use for production.

You'll also need to set the keys and Facebook secrets as environment variables. See secrets.yml for which ones you need to set. These are in the Events@Penn Dev app on Facebook. Ask the Director of Web Development if you need to be added to the app!

Run rake db:drop, rake db:create, and rake db:migrate to clear and set up the database tables. Run rails s, and go to localhost:3000 in your browser of choice to see the app!


Events@Penn uses Capistrano to deploy to a server on Google Cloud. You can read more here about how Capistrano works, but at a high level, it uses SSH to deploy files to a remote server and run commands as defined in the Capfile and config/deploy files.

  1. Download the dp_master_rsa public and private keys. They can be found on Google Drive, or ask someone for them. Put them in your ~/.ssh folder.
  2. Edit (or create, if you don't currently have one), a ~/.ssh/config file. Add the following line:
      IdentityFile ~/.ssh/dp_master_rsa
  3. Run cap production deploy. This will use the production.rb configuration file to deploy the app to our production server.

Capistrano deploys the app to a folder called html in the rails user's home folder. This folder is symlinked to /var/www/html, which nginx serves. Capistrano then restarts puma, the webserver, and nginx, the reverse proxy.
