ckanext-hierarchy - Organization hierarchy for CKAN

Provides a new field on the organization edit form to select a parent organization. This new hierarchical arrangement of organizations is displayed using templates in this extension, instead of the usual list. An organization page also displays the section of the tree that it is part of, under the 'About' tab.

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 works 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"
}

TODO:

• make the trees prettier with JSTree
