# ckanext-comments
Add comment-trees to CKAN pages.
This plugins provides comment threads linked to any of the main CKAN entities:
* datasets
* resources
* groups
* organizations
* users.
All the features are API-first, so anything you can do via UI, can be done via API.
No changes to the WebUI are done by default. One have to include a snippet into
Jinja2 template in order to show the comments on a page.
```jinja2
{# subject_type := package | group | resource | user #}
{% snippet 'comments/snippets/thread.html', subject_id=pkg.id, subject_type='package' %}
```
:info: For the datasets it also can be achieved by enabling
`ckanext.comments.enable_default_dataset_comments` option.
