Configuration Files



Note

Changes to configuration files often require restarting Avalon to take affect. They also require Sidekiq (the background jobs processor) to be restarted.

It's recommended to override the default settings by creating a config/settings/<environment>.local.yml instead of modifying the config/setings.yml directly.

You can also use environment variables, for example SETTINGS__DOMAIN__HOST maps to Settings.domain.host.



Since the Config gem doesn't support arrays in environment variable, Settings.auth.configuration requires a key for every entry, e.g.:

  SETTINGS__AUTH__CONFIGURATION__IU__NAME=Indiana University SETTINGS__AUTH__CONFIGURATION__IU__PROVIDER=cas SETTINGS__AUTH__CONFIGURATION__IU__PARAMS__CLIENT_ID=client_id_value SETTINGS__AUTH__CONFIGURATION__IU__PARAMS__CLIENT_SECRET=client_secret_value

Notes

Managing Master Files explains available strategies for how avalon can handle master files after they have been processed. 

Bibliographic Import Configuration explains how to configure Avalon to import metadata from an external source such as an OPAC.

Config overwrites should be placed in config/settings/<environment>.local.yml

If using env var, set SETTINGS__EMAIL__MAILER=aws_sdk to send emails using Amazon SES 



config/database.yml

Purpose

Environment-specific database connection information for Rails.

Format

YAML

Example

production:
adapter: mysql2
host: localhost
database: rails
username: rails
password: rails
pool: 5
timeout: 5000 

Notes

See Configuring a Database in the Ruby on Rails Getting Started Guide for more options. Changing the database adapter will require updating Gemfile to require the correct adapter. Here are the instructions for installing the mysql adapter called mysql2.



config/fedora.yml

Contents

Environment-specific Fedora repository connection information for Hydra

Format

YAML

Example

production:
user: fedoraAdmin
password: fedoraAdmin
url: http://127.0.0.1:8984/fedora4/rest
base_path: /prod 



config/intercom.yml

Contents

Configuration for optional Intercom feature. Allows this instance on Avalon to push contents to another instance of Avalon.

Format

YAML

Example

intercom:
  default:
    url: https://some.avalon.com/
    api_token: a_valid_token
    import_bib_record: true
    publish: false
push_label: text for the 'push' button

Notes

Intercom utilizes the Ingest API and requires an API token to connect. This token is generated on the target Avalon with `bundle exec rake avalon:token:generate username=archivist email=archivist1@example.com`

The streaming files will remain in place. Both instances of Avalon must be able to stream from that location.



config/solr.yml

Purpose

Environment-specific Solr connection information for Hydra

Format

YAML

Example

production:
url: http://localhost:8983/solr/avalon



config/role_map_<environment>.yml

Contents

Role groups and associated members to initialize the Hydra access controls database with

Format

YAML

Example

collection_manager:
- archivist1@example.edu
- archivist2@example.edu
group_manager:
- donor1@example.com
manager:
- researcher1@example.edu
administrator:
- user1@example.edu
- user2@otherinstitution.edu

Notes

Example environments: development, production, test. So the filename would look like role_map_production.yml for the production environment.

config/controlled_vocabulary.yml

See Controlled Vocabularies.

config/secrets.yml

Rails 4+ uses a secrets.yml file to store a secret key used for signed cookies as well as other things.  See http://edgeguides.rubyonrails.org/upgrading_ruby_on_rails.html#config-secrets-yml for more information.
