Summary Of Source/Deposit Collection Adjustments

Overview

Just after the launch of Curate v1, it was determined that the greater the number of Works that are associated with a single Collection, the longer that any further ingestions of Works to that Collection would take. The best solution to this issue was to create, in essence, sub-containers for each primary Collection. The original Collection would take on the moniker of "Source", while the secondary collections would be deemed "Deposit". Works would hold associations to both their direct and overarching parents (sometimes the same Collection). Several customizations upon our Hyrax backbone were needed to implement the parent/child relationships. Below, you will find descriptions of these changes grouped by class and module types.

Models

Collection

:deposit_collection_ids: this multi-value attribute was added to retain all of the child collection IDs that are associated to a Collection instance. The presence of IDs in an instance means that it is a Source Collection.
:source_collection_id: a single-valued field that holds the parent collection ID. An ID populated in this field means that object is a Deposit Collection.

CurateGenericWork

:source_collection_id: this required field ties the Work to the Source Collection with an ID string.

SolrDocument

#source_collection_title: a method allowing the SolrDocument rails object to access the value of source_collection_title_ssim as if it were stored in ActiveRecord.

Views

hyrax/admin/collection_types/_form_settings.html.erb

A checkbox is inserted at line 41 to give a new CollectionType the option of being deposit-only.

hyrax/base/_relationships_parent_rows.html.erb

On lines 17 through 25, a Source Collection header and link is added to this Work show page partial.

hyrax/collections/_deposit_collections.html.erb

This is a new partial that inserts a header and Deposit Collection link(s) for a Source Collection's show pages.

hyrax/collections/_source_collection.html.erb

This is a new partial that inserts a header and Source Collection link for a Deposit Collection's show pages.

hyrax/collections/show.html.erb

Between lines 98 and 102, inserts partial calls to both the Deposit and Source Collection links html.

hyrax/dashboard/collections/show.html.erb

This Hyrax page overwrite only reflects changes between lines 64 and 76. Here, we are inserting two partial calls to the Deposit and Source Collection links html.

records/edit_fields/_deposit_collection_ids.html.erb

A partial that effectively overrides Hyrax/Simple Form's default input tag so that only admins can adjust the deposit_collection_id field. Also institutes a multi-valued pull-down filled with all Collection objects.

records/edit_fields/_source_collection_id.html.erb

Another override of Hyrax/Simple Form's default input tag that restricts the source_collection_id field to admins only. This institutes a single-valued pull-down filled with all Collection objects.

Controllers

CatalogController

The Collection facet field now uses source_collection_title_ssim as it's filter value.

Hyrax::Admin::CollectionTypesControllerOverride

This only overrides the #collection_type_params method from Hyrax::Admin::CollectionTypesController, adding :deposit_only_collection into the permitted params.

Assets

stylesheets/curate.scss

The scss between lines 103 and 106 adjusts the padding and margin for the Source Collection link on Collection show pages.

Forms

hyrax/forms/admin/collection_type_form.rb

Hyrax::Forms::Admin::CollectionTypeForm had to be overridden so that :deposit_only_collection could be delegated to :collection_type.

hyrax/forms/collection_form.rb

:source_collection_id and :deposit_collection_ids had to be added to the terms and secondary_terms arrays, since it feeds the logic that automatically generates Collection's new/edit input fields.

hyrax/curate_generic_work_form.rb

:source_collection_id had to be added to the terms and primary_admin_metadata_fields arrays, since it feeds the logic that automatically generates Works' new/edit input fields.

Helpers

CollectionShowHelper

#collection_link dynamically creates the right link based upon whether the user's on the Dashboard or the public Collection show page.

FormHelper

#all_collections_collection creates an array of arrays each containing Collection object's titles and ids. This supplies the select fields' collection attributes in the Collection new/edit forms.

Importers

CurateMapper

source_collection_id is added to CURATE_TERMS_MAP so that it is expected and accepted during CSV imports.

LangmuirPreprocessor

Curate's Product Owner specified that source_collection_id should be on the processed CSV output, even if it is not present on the input file. The exclusion_guard method was applied to the @merged_headers instance variable so that it is inserted if not found in the @source_csv.headers.

YellowbackPreprocessor

source_collection_id is inserted into HEADER_FIELDS, so that the field is included in the output file, and pull_list_mappings, in order for the values to be pulled from the input CSV.

Indexers

CurateCollectionIndexer

source_collection_title_for_collections_ssim and deposit_collection_titles_tesim: both of these fields are stubbed with the :title attribute associated to the object's respective Source and Deposit Collection values.
deposit_collection_ids_tesim: declared here to ensure solr_document objects carry the Deposit Collection IDs over.

Jobs

CollectionFilesIngestedJob

#collection_works: with the search originally focused on :member_of_collection_ids_ssim to match with the current collection_id, this had to swap out to :source_collection_id_tesim.
#source_collections: this logic had to be added so that the focus shifted to Collections with CollectionTypes not set to Deposit-Only.

Presenters

Hyrax::CollectionPresenter

The following methods were added to the Presenter so that Deposit and Source Collection details could pass over to the Collection views

#deposit_collection?: this is a boolean method that returns true if the object is a Deposit Collection.
#source_collection_object: returns a hash of Source Collection :title and :id.
#deposit_collection_ids: pulls the needed Deposit Collection IDs from the solr_document.
#deposit_collections: creates an array of hashes, each containing the :title and :id of every Deposit Collection associated to the object.

Hyrax::CurateGenericWorkPresenter

:source_collection_title is delegated to the :solr_document so that presenter.source_collection_title calls won't look for a method created within the class.

Search Builders

Hyrax::CollectionMemberSearchBuilder

This class was pulled in as an overwrite of Hyrax' class so that #member_of_collection could include Collections' associated Deposit Collection Works alongside the Source Collection Works.

Initializers

Hyrax::My::WorksController

self.configure_facets: this method is created and called so it can tap into the original configure_blacklight grid and add in a facet labeled "Source Collection" onto the Works index.

Config

application.rb

In order to overwrite Hyrax::Admin::CollectionTypesController effectively, we have to prepend CollectionTypesControllerOverride onto it here.

DB/Migrate

AddDepositOnlyCollectionToHyraxCollectionTypes

Added :deposit_only_collection onto the :hyrax_collection_types table so future Collections can have a Deposit-Only CollectionType.
