Setting up the demo app

back to Introduction

Goals

• Set up a new Rails application with PostGres as the database.
• Install Valkyrie.
• Set up .gitignore (recommended if committing your demo app to GitHub).

---

To set up a new Rails app with Postgres, open a terminal and run the following command:

rails new valkyrie_pg_demo --database=postgresql

Enter the directory for your demo app:

cd valkyrie_pg_demo

Add Valkyrie to the app

Edit Gemfile at the root of the app and after # gem 'mini_racer', platforms: :ruby, add the following line:

gem 'valkyrie'

To install the gem, run the following command in the terminal:

bundle install

Alternatively, run this command adding the bundled gems to the vendor/bundle directory in the app:

bundle install --path=vendor/bundle

This alternative technique will install your gems as a set of dependencies isolated specifically to this demo.

Set up .gitignore

If you plan to commit the demo to version control, and you have installed your gems through vendor/bundle, you can add a .gitignore file and add the following lines, so all of your gems do not get added to version control:

# Ignore vendor/cache and bundle
/vendor/cache
/vendor/bundle
