City of Surrey CKAN extension

CKAN extension development for the implementation of the City of Surrey

The extension contains the following features:

  • Add a custom CSS file
  • Add custom pages (contact & suggest dataset forms + follow page) with implementation of iRoutes
  • Add public file (images)
  • Add custom licence
  • Add predefined extra fields at the dataset level
  • Support custom templates
  • Remove ‘organization’ from the facet list and various other places

More documentation available in ckanext/surrey/docs/customization.md

Prerequisite

This extension needs the stats extension to be activated with the tracking options. Some links (in the footer), also need the ckanext-page extension. So install ckanext-page

pip install -e git+https://github.com/ckan/ckanext-pages.git#egg=ckanext-pages

Then configure the plugins in the .ini file:

ckan.plugins =  ... stats pages...
ckan.tracking_enabled = true 

The template need the follow pages to be created:

  • faq
  • glossary
  • open-government-licence
  • city-of-surrey-open-data-api

In order to refresh the most popular dataset values on the landing page, make sure to set up the cron jobs (see below).

The extension has been developed and tested to run with CKAN 2.2.

Installation

Activate your pyenv and go to the CKAN root, for example:

 cd /usr/lib/ckan/default/
 source bin/activate
 cd src/ckan

Install the extension from GitHub:

pip install -e git+git://github.com/CityofSurrey/ckanext-surrey.git#egg=ckanext-surrey

To access a specific release, for example release-1.0:

pip install -e git+git://github.com/CityofSurrey/ckanext-surrey.git@release-1.0#egg=ckanext-surrey

Add the extension in the configuration file. surrey does most of the work, surreyfacet mainly removes the organization from the facet menu

ckan.plugins =  ... surrey surreyfacet surreyextrapages

Add the custom licence file in the configuration file.

licenses_group_url = file:///path/to/extension/ckanext-surrey/ckanext/surrey/licences.json

Set up jobs

Some cron jobs have to be set up in order to have the extension working as expected.

In order to update the recent visits, the tracker and the index has to be rebuilt. The following command will do this using crontab -e (make sure that the path to paster and the .ini file correspond to your installation):

@hourly /usr/lib/ckan/default/bin/paster --plugin=ckan tracking update -c /etc/ckan/default/production.ini > /dev/null
@hourly /usr/lib/ckan/default/bin/paster --plugin=ckan search-index rebuild -r -c /etc/ckan/default/production.ini > /dev/null

In order to receive mail notification (either for the admin and for the users who are registering) add the following comming in the cron jobs:

@daily echo '{}' | /usr/lib/ckan/default/bin/paster --plugin=ckan post -c /etc/ckan/default/production.ini /api/action_notifications > /dev/null
