Installation/Setup

Installation Prerequisites

See the Installation Prerequisites wiki page.

Ruby 2.1.0+ is required by Hydra-Head release 10+; RVM is strongly suggested.

Install Rails

gem install 'rails' --version '~>5.1.0'

Generate a new rails application:

rails new my_hydra_head
cd my_hydra_head

Install Dependencies

First, add them to the Gemfile of your application. The new rails application you just generated will have generated a Gemfile; add blacklight and hydra-head as below:

  source 'https://rubygems.org'

  gem 'rails'
  gem 'blacklight'
  gem 'hydra-head', '~> 10.0'

To install all of the dependencies, run:

bundle install

Run the generators and migrations:

Run the blacklight generator

rails g blacklight:install --devise

Run the hydra-head generator

rails g hydra:head -f

Run the database migrations

rake db:migrate

You're done.

Congratulations. You've set up the code for your Hydra Head.
