Development

TO DO: Move this into the wiki

Prerequisites

The developer environment relies on Docker Engine and Docker Compose. Make sure you're running the latest versions.

Installation or upgrade instructions for Docker Compose and Docker Engine are available on their respective sites.

Getting started

First, clone the repo from GitHub:

git clone git@github.com:UCLALibrary/californica.git
cd californica

After that, you can run docker-compose to bring up the development environment:

docker-compose up

The first time you create the environment, you'll also need to provision the databases. From within the californica directory, run:

docker-compose run web bash
bundle exec rake db:setup
bundle exec rake hyrax:default_admin_set:create

If this succeeds without error, you've successfully created your Californica environment.

To access some of the services that you'll need, try finding them at the following locations:

• Californica -> http://localhost:3000/
• Fedora -> http://localhost:8984/
• Solr -> http://localhost:8983/solr/#/

Default admin user

A default admin user is created for you, with the e-mail address of admin@example.com, and a password of 'password' This password can and should be set by way of a dot-env variable ADMIN_PASSWORD. See the .env.sample file for an example.

Creating a new admin user

First, create the user via the UI, or have them self-register.

Then, on the rails console:

u = User.find_by_user_key('example@library.ucla.edu')
admin = Role.find_by_name('admin')
admin.users << u
admin.save
u.admin?
  => true

If u.admin? returns true then you know it worked as expected.

See also the Making Admin Users in Hyrax Guide.

Loading data

You can load data from a csv via the Hyrax Dashboard interface.

Deployment

Prerequisites/Assumptions:

• A local rails app development environment is provisioned
• bundle install completes successfully
• Capistrano is installed as a part of the environment
• A deploy file exists that defines the destination host where code should be deployed. The relative path within the code base is config/deploy/target_system.rb - where target_system is an identifier for the destination host where code will be deployed. Sample file contents are:

server 'californica-test.library.ucla.edu', user: 'deploy', roles: [:web, :app, :db]

This should already be available for you, but good to verify so you know where your deploy is going.

To deploy code using Capistrano to a UCLA Library server

1. Within your local development environment, become a user that has the following attributes:

• ownership of the files within your local copy of the code base
• ssh public key is installed in the authorized_keys file for your user account on the UCLA Library jump server
• ssh public key is installed in the authorized_keys file for the deploy user account on the destination server where code will be deployed
• if you need your public keys installed - please reach out to the DevSupport team for assistance

2. Ensure you are in the project code directory and execute:

  VIA_JUMP=yes BRANCH=master bundle exec cap target_system deploy

Where target_system matches the filename used by the target_system.rb deploy file.

This will execute the deploy, tunneling through the Library's jump server.

If your local environment username is different than your username on the jump server, execute:

  JUMP_USER=YOUR_JUMP_USERNAME VIA_JUMP=yes BRANCH=master bundle exec cap target_system deploy

Importing from CSV

Character Encoding

When importing from a CSV file it is important to ensure that the character encoding remains UTF-8.

If you need to make manual edits to a CSV export before importing do not use Excel unless it is version 2016 or higher. Older versions of Excel will change the encoding when you save the file and re-export it as CSV. Current versions of Excel will have an option to export as 'UTF-8 CSV', which should be used. Google Sheets or LibreOffice Calc will allow you to make manual edits and maintain the correct encoding when saving.

Import Process

Use the rake californica:ingest:csv task, and specify the CSV_FILE and IMPORT_FILE_PATH when you invoke it.

In the docker-compose development environment, /opt/data/ mounts the californica/data directory from your host machine. This directory is empty by default and included in .gitignore, so you'll need to obtain the data on your own and put it here: metadata CSVs are stored in the box drive and master images are on the Netapp Masters volume.

Once the data is in place, the ingest command looks something like:

CSV_FILE=/opt/data/ladnn/dlcs-dlcs_ladnn-2018-12-12.csv IMPORT_FILE_PATH=/opt/data/ladnn/ bundle exec rake californica:ingest:csv

In our server environments, csv files are copied to /opt/data/ and the entire Masters volume is mounted at /opt/data/Masters/. To set the IMPORT_FILE_PATH variable, you will need to find the directory within Masters that contains the collections image files. For example:

CSV_FILE=/opt/data/ladnn/dlcs-dlcs_ladnn-2018-12-12.csv \
IMPORT_FILE_PATH=/opt/data/Masters/dlmasters/ladailynews/image/ \
bundle exec rake californica:ingest:csv

Adding works to a collection

You can add a Parent ARK column to the CSV file. For each row of the CSV, add the ARK for the collection that work should belong to. The importer will find the Collection record with the matching ARK. If the Collection record doesn't exist yet, the importer will create a new Collection using that ARK.

Read-only mode

Californica has a read-only mode, which can be enabled via the Settings menu on the admin dashboard, and is useful for making consistent backups or migrating data.

Ideally, a user should log in as an admin, enable read-only mode, and keep the window open so they can then disable it again. If the window accidentally gets closed, and the system is stuck in read-only mode, open a rails console and fix the problem like this:

% RAILS_ENV=production bundle exec rails c
irb(main):006:0> Hyrax::Feature.where(key: "read_only").first.destroy!

What is Hyrax, what is Californica?

Hyrax is a Rails Engine providing a base platform for digital repositories of various types. This includes Institutional/Document Repositories, Digital Collections DAMS, as well as other kinds of digital library and archives systems.

Californica is an application providing a general purpose repository system based on the Hyrax platform. Californica gives you the most commonly used Samvera features and functions.

This application is designed as a management interface for UCLA's digital library content.
