A Rails engine with models for the Innovative Interfaces Inc. Sierra integrated library system Postgresql database backend.
Add this line to your application's Gemfile:
gem 'active_sierra'
And then execute:
$ bundle
Or install it yourself as:
$ gem install active_sierra
Additionally, add 'sierra' to your config/database.yml, to connect to your local database:
sierra:
adapter: postgresql
database: iii
host: your_database_url
port: your_database_port
schema_search_path: sierra_view
pool: 5
timeout: 5000
username: your_username
password: your_password
sslmode: require
The engine provides models for major records types in the Sierra database, per the SierraDNA documentation (authentication required).
Record models currently include:
- BibView
- ItemView
- OrderView
- VarfieldViews
- Subfields
BibRecord, ItemRecord, and OrderRecord are also included because they respond more quickly to certain queries
Relationships between records are included, e.g.:
b = BibView.first
i = b.item_views
b = i.bib_views ## Returns all attached bib records (items can have more than one attached bib record)
o = OrderView.first
b = o.bib_view ## Returns single attached bib record (orders, and checkins can only have one attached bib)
All records have attached variable fields, expressed through the VarfieldViews model:
v = b.varfield_views
And variable fields each have sub-fields:
v.subfields
The *View/*Record types also have creation\deletion data in an associated table:
b.record_metadata
