[ckan-dev] Disqus comments plugin SSO enhancement

Mon Nov 17 21:42:02 UTC 2014

Adrià,

Thanks for the pointers; I am now able to access the user data.  One small change from the code you provided was needed (in case anyone else tries this):

I had to use c.user in the get_action:
  user_dict = p.toolkit.get_action('user_show')({'keep_email': True}, {'id': c.user})

As opposed to using c.name as you suggested: 
    user_dict = p.toolkit.get_action('user_show')({'keep_email': True}, {'id': c.name})

Now on to see implementing the Single Sign On...

Andrew

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
