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+.


------------
Installation
------------

.. Add any additional install steps to the list below.
For example installing any non-Python dependencies or adding any required
config settings.

To install ckanext-showcase:

1. Activate your CKAN virtual environment, for example::

. /usr/lib/ckan/default/bin/activate

2. Install the ckanext-showcase Python package into your virtual environment::

pip install ckanext-showcase

3. Add ``showcase`` to the ``ckan.plugins`` setting in your CKAN
config file (by default the config file is located at
``/etc/ckan/default/production.ini``).

4. Restart CKAN. For example if you've deployed CKAN with Apache on Ubuntu::

sudo service apache2 reload


------------------------
Development Installation
------------------------

To install ckanext-showcase for development, activate your CKAN virtualenv and
do::

git clone https://github.com/ckan/ckanext-showcase.git
cd ckanext-showcase
python setup.py develop
pip install -r dev-requirements.txt

API
---

All actions in the Showcase extension are available in the CKAN Action API.

Showcase actions::

curl -X POST http://127.0.0.1:5000/api/3/action/ckanext_showcase_create -H "Authorization:{YOUR-API-KEY}" -d '{"name": "my-new-showcase"}'

- delete a showcase (sysadmins and showcase admins only)
curl -X POST http://127.0.0.1:5000/api/3/action/ckanext_showcase_delete -H "Authorization:{YOUR-API-KEY}" -d '{"name": "my-new-showcase"}'

- show a showcase
curl -X POST http://127.0.0.1:5000/api/3/action/ckanext_showcase_show -d '{"id": "my-new-showcase"}'

- list showcases
curl -X POST http://127.0.0.1:5000/api/3/action/ckanext_showcase_list -d ''


Dataset actions::

- add a dataset to a showcase (sysadmins and showcase admins only)
curl -X POST http://127.0.0.1:5000/api/3/action/ckanext_showcase_package_association_create -H "Authorization:{YOUR-API-KEY}" -d '{"showcase_id": "my-showcase", "package_id": "my-package"}'

- remove a dataset from a showcase (sysadmins and showcase admins only)
curl -X POST http://127.0.0.1:5000/api/3/action/ckanext_showcase_package_association_delete -H "Authorization:{YOUR-API-KEY}" -d '{"showcase_id": "my-showcase", "package_id": "my-package"}'

- list datasets in a showcase
curl -X POST http://127.0.0.1:5000/api/3/action/ckanext_showcase_package_list -d '{"showcase_id": "my-showcase"}'

- list showcases featuring a given dataset
curl -X POST http://127.0.0.1:5000/api/3/action/ckanext_package_showcase_list -d '{"package_id": "my-package"}'


Showcase admin actions::

- add showcase admin (sysadmins only)
curl -X POST http://127.0.0.1:5000/api/3/action/ckanext_showcase_admin_add -H "Authorization:{YOUR-API-KEY}" -d '{"username": "bert"}'

- remove showcase admin (sysadmins only)
curl -X POST http://127.0.0.1:5000/api/3/action/ckanext_showcase_admin_remove -H "Authorization:{YOUR-API-KEY}" -d '{"username": "bert"}'

- list showcase admins (sysadmins only)
curl -X POST http://127.0.0.1:5000/api/3/action/ckanext_showcase_admin_list -H "Authorization:{YOUR-API-KEY}" -d ''


----------------------------
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


------------------------------------
Registering ckanext-showcase on PyPI
------------------------------------

ckanext-showcase should be availabe on PyPI as

2. Register the project::

python setup.py register

3. Upload the source distribution to PyPI::

python setup.py sdist upload

4. Tag the first release of the project on GitHub with the version number from
the ``setup.py`` file. For example if the version number in ``setup.py`` is
0.0.1 then do::
