ckanext-package-group-permissions

A CKAN extension to allow any user with admin or editor role in an organisation to assign datasets in their organisation to any group in CKAN.

Compatibility

This extension has been tested with CKAN v2.8.3 & v2.9.2.

While not tested with v2.7.0+ - the required permission was changed from 'update' to 'manage_group' in v2.7.0, so this should work in v2.7.0+.

Our use case

We wanted the ability for any user with admin or editor role in an organisation to be able to assign datasets in their organisation to any group in CKAN.

Previously, this was handled manually, i.e. each admin/editor user was assigned as an admin of each group in CKAN by adding them via the API. This process was very time consuming as the number of admins/editors and groups increased.

We tried implementing the suggestions outlined in this Stack Overflow question: https://stackoverflow.com/questions/37279610/ckan-package-group-permissions - however we were unable to get it working as desired.

Our solution

Our solution ended up being a little simpler for our requirements:

Override CKAN member_create function

The overridden function is largely based on the core CKAN member_create function, with an additional check to see if the user is an admin or editor of the organisation that owns the dataset.

Template overrides

This solution also requires some CKAN templates to be overridden:

templates/package/group_list.html

Overridden to display all groups to the user if the user has package_update permission for the dataset.

If the user does not have package_update permission - it falls back to the CKAN default of displaying only the groups that user is assigned to.

templates/group/snippets/group_item.html

Overridden to display the delete button on a group assigned to the dataset if the user has member_delete permission for the group.

This also supports the default CKAN behaviour to display the delete button on any groups that user is assigned to.

Installation

  1. Clone this repository into your CKAN extensions directory, e.g. /usr/lib/ckan/default/src

  2. Activate your virtualenv and run the setup.py, e.g.

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

 cd ckanext-package-group-permissions

 python setup.py develop

  3. Add package_group_permissions to ckan.plugins in your CKAN .ini file, e.g.

     ckan.plugins = ... package_group_permissions

  4. Restart Apache/Nginx/UWSGI
