Showcase and link to datasets in use. Datasets used in an app, website or visualization, or featured in an article, report or blog post can be showcased within the CKAN website. Showcases can include an image, description, tags and external link. Showcases may contain several datasets, helping users discover related datasets being used together. Showcases can be discovered by searching and filtered by tag.
Site sysadmins can promote selected users to become 'Showcase Admins' to help create, populate and maintain showcases.
ckanext-showcase is intended to be a more powerful replacement for the 'Related Item' feature.
Compatible with CKAN 2.3+.
N.B. The migrate
command, detailed below, requires the Related Item models
and actions, which have been removed in CKAN 2.6. If you wish to migrate your
Related Items, please first upgrade CKAN to 2.5, do the migration, then
continue upgrading to CKAN 2.6+.

If you already have Related Items in your database, you can use the showcase migrate
command to create Showcases from Related Items.
From the ckanext-showcase
directory::
paster showcase migrate -c {path to production.ini}
Note that each Related Item must have a unique title before migration can proceed. If you prefer resolving duplicates as showcases, you can use the --allow-duplicates option to migrate them anyways. Duplicate Relations will be created as 'duplicate_' + original_relatedtitle + '' + related_id
paster showcase migrate -c {path to production.ini} --allow-duplicates
The Related Item property type
will become a Showcase tag. The Related Item
properties created
, owner_id
, view_count
, and featured
have no
equivalent in Showcases and will not be migrated.
Related Item data is not removed from the database by this command.
To run the tests, do::
nosetests --ckan --nologcapture --with-pylons=test.ini
To run the tests and produce a coverage report, first make sure you have
coverage installed in your virtualenv (pip install coverage
) then run::
nosetests --ckan --nologcapture --with-pylons=test.ini --with-coverage --cover-package=ckanext.showcase --cover-inclusive --cover-erase --cover-tests
