[ckan-dev] Disqus comments plugin SSO enhancement

Wed Dec 3 17:01:40 UTC 2014

I have what appears to be a functional fork of the ckanext-disqus extension that integrates the Disqus Single Sign On.  This allows CKAN users to comment without having to establish a separate username/password with Disqus.  If anyone would like to try installing it, it is at:

https://github.com/exlibris/ckanext-disqus

To use SSO you need to jump through various hoops with Disqus (i.e. register your application, get keys...) and them put the keys in your CKAN .ini file.  See my documentation for more info.  The extension should also still work in the prior fashion if the required keys are not in the .ini file.

I read through the documentation on contributing to CKAN and making pull requests (http://docs.ckan.org/en/latest/contributing/pull-requests.html) and unfortunately was not able to follow the steps exactly: I was unable to create a branch on the main repo prior to forking.  So I just forked and made my changes to the master.  If the maintainers of the main repo would like to integrate these changes into the main extension, and I can do anything at my end to make this easier just let me know.  This is my first attempt at both writing python and contributing to a github project, so suggestions on how to improve my coding  and git skills are welcome.

Hi Andrew,

To access properties in c you need to access them like `c.user`. This gives you the user name.

Passing data in c to the templates is not the recommended method any more. Passing variables as in here is recommended:

https://github.com/ckan/ckanext-disqus/blob/master/ckanext/disqus/plugin.py#L92:L96

These can be later accessed from the templates directly:

https://github.com/ckan/ckanext-disqus/blob/master/ckanext/disqus/templates/disqus_comments.html#L5:L6

In your case you need to call `user_show` to get all the extra details you need, something like this should get you started:

    user_dict = p.toolkit.get_action('user_show')({'keep_email':
True}, {'id': c.name})

    data = {
        ...
       'user_id: user_dict['id'],
       'user_name': user_dict['name'],
       'user_email': user_dict['email'],
    }
return p.toolkit.render_snippet('disqus_comments.html', data)

Hope this helps,

Adrià
