ckanext-showcase
================

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.


------------
Requirements
------------


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+.

----------------------------
Migrating from Related Items
----------------------------

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_related_title + '_' + 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.

-----------------
Running the Tests
-----------------

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
