ckanext-hierarchy - Organization hierarchy for CKAN

Organizations can be arranged into a tree hierarchy.

This new hierarchical arrangement of organizations is displayed using templates in this extension, instead of the usual list: Screenshot of organizations page

Provides a new field on the organization edit form to select a parent organization: Screenshot of organization edit page

When viewing an organization you see its context within the tree in the side bar. In addition you can widen search of the organization's datasets to include datasets in sub-organizations too: Screenshot of organization page

Technical details

Forms (hierachy_form plugin):

  • /organization/new
  • /organization/edit/{id}

Templates (hierarchy_display plugin):

  • /organization - now shows the organization hierarchy instead of list
  • /organization/about/{id} - now also shows the relevant part of the hierarchy

Snippets (used by hierarchy_display and ckanext-scheming):

  • /scheming/form_snippets/org_hierarchy.html

You can use this extension with CKAN as it is, enabling both plugins. Or if you use an extension to customise the form already with an IGroupForm, then you will want to only use the hierarchy_display plugin, and copy bits of the hierarchy_form into your own. If you have your own templates then you can use the snippets (or logic functions) that this extension provides to display the trees.

In order to make hierarchy work with ckanext-scheming you need to enable just hierarchy_display and then use corresponding form_snippet in your org_schema. For example, you may add next field:

{
    "field_name": "not_used",
    "label": "Parent organization",
    "display_snippet": null,
    "form_snippet": "org_hierarchy.html",
    "validators": "ignore_missing"
}

Optionally one could also specify a full name and leave the field 'title' for the short name or acronym (more convenient for display).

{
    "field_name": "longname",
    "label": "Full Name",
    "validators": "ignore_missing unicode",
    "form_snippet": "large_text.html",
    "form_attrs": {"data-module": "slug-preview-target"},
    "form_placeholder": "My Organization full name",
    "display_snippet": null
}

TODO:

  • make the trees prettier with JSTree

Requirements

This extension requires CKAN v2.7 or later.

Installation

To install ckanext-hierarchy:

  1. Activate your CKAN virtual environment, for example:

    . /usr/lib/ckan/default/bin/activate
    
  2. Install the ckanext-hierarchy Python package into your virtual environment:

    cd /usr/lib/ckan/default/src
    pip install -e "git+https://github.com/davidread/ckanext-hierarchy.git#egg=ckanext-hierarchy"
    pip install -r ckanext-hierarchy/requirements.txt
    
  3. Add hierarchy_display and hierarchy_form to the ckan.plugins setting in your CKAN config file (by default the config file is located at /etc/ckan/default/production.ini). Note that hierarchy_display should come before hierarchy_form

    e.g.:

    ckan.plugins = stats text_view recline_view ... hierarchy_display hierarchy_form
    
  4. Restart CKAN. For example if you've deployed CKAN with Apache on Ubuntu:

     sudo service apache2 reload
    

Config settings

None at present

To run the tests, do::

nosetests --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 --nologcapture --with-pylons=test.ini --with-coverage --cover-package=ckanext.hierarchy --cover-inclusive --cover-erase --cover-tests
