A ckan extension to showcase datasets in use
Project description
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
Tested on CKAN 2.7 to 2.10..
Installation
To install ckanext-showcase:
Activate your CKAN virtual environment, for example:
. /usr/lib/ckan/default/bin/activate
Install the ckanext-showcase Python package into your virtual environment:
pip install ckanext-showcase
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).
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
The extension contains a custom build of CKEditor to allow using a WYSIWYG editor to write the content of the showcase. It has been built using webpack and the repository contains all the files needed to edit and customize it if needed:
npm install npx webpack --config webpack.config.js
The webpack will use as entrypoint a file located in ckanext/showcase/fanstatic/src/ckeditor.js, create a build and save it to ckanext/showcase/fanstatic/dist/ckeditor.js

UI
The Showcase extension adds the following pages to the user interface:
The main showcase index is available on: http://127.0.0.1:5000/showcase
To create a new showcase: http://127.0.0.1:5000/showcase/new
To edit or delete a showcase: http://127.0.0.1:5000/showcase/edit/{showcase-name}
To add a Showcase Admin : http://127.0.0.1:5000/ckan-admin/showcase_admins
Configuration
If you want to use the WYSIWYG editor instead of Markdown to write the content of the showcase:
ckanext.showcase.editor = ckeditor
Migrating Showcases Notes from Markdown to HTML
When using CKEditor as WYSIWYG editor showcases notes are stored in HTML instead of Markdown. To migrate all existing notes from markdown to HTML you can use the `showcase markdown_to_html` command.
From the ckanext-showcase directory:
paster showcase markdown-to-html -c {path to production.ini}
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
