Disqus Extension

The Disqus extension allows site visitors to comment on individual packages using an AJAX-based commenting system. The downsides of this plugin are that comments are not stored locally and user information is not shared between CKAN and the commenting system.

Note: This extension requires ckan 1.7 or higher

Activating and Installing

In order to set up the Disqus plugin, you first need to go to disqus.com and set up a forum with your domain name. You will be able to choose a forurm name.

To install the plugin, enter your virtualenv and load the source:

(pyenv)$ pip install -e git+https://github.com/okfn/ckanext-disqus#egg=ckanext-disqus

For ckan versions before 2.0, please use the release-v1.8 branch.

This will also register a plugin entry point, so you now should be able to add the following to your CKAN .ini file:

ckan.plugins = disqus <other-plugins>
disqus.name = YOUR_DISQUS_NAME

At this point, each dataset view page will have Disqus comments. To add comments into other pages, see the next section.

Using the Extension

Comments Threads

To have comment threads appear on pages, insert into templates where you want the comments to appear:

Note for theme developers: the extensions tries to generate a disqus_identifier of the form:

{controller/domain-object-name}::{id}

Where controller = ‘group’ in the group section, ‘dataset’ in the dataset section (note that this differs from controller name internally which is still package), ‘resource’ for resources etc. This identifier will be useful if you want to then reference this comment (e.g. for comment counts) elsewhere in the site.

Recent comments

Insert on pages where you want recent comments to appear:

The recent comments widget will show 5 recent comments by default. To show 10 recent comments use the following:

Other widgets

Disqus offers many other widgets. Rather than providing these automatically as part of this extension we suggest that theme developers incorporate the code directly (note that you access the relevant config variables from the config object passed into all templates).

Single Sign On ~~~~~~~~~~~~~

Disqus offers a “Single Sign On” option which allows users to submit comments using the local username/password rather than require a seperate disqus account. For instructions on how to set things up on the Disqus end (i.e. create API keys) see: https://help.disqus.com/customer/portal/articles/236206-integrating-single-sign-on

To integrate with this CKAN plugin, you must store your Public and Secret keys in the CKAN ini file:

ckan.plugins = disqus <other-plugins>
disqus.name = YOUR_DISQUS_NAME
disqus.secret_key  = YOUR_DISQUS_SECRET_KEY
disqus.public_key  = YOUR_DISQUS_PUBLIC_KEY
