Xavier Dutoit	Wednesday 29 March 2006 2:17:38 am Hi, I don't find any sort_by option that would allow me to sort the content by the number of children (eg. get the list of articles that got the most comments). Am I blind ? Any advice or suggestion on how to do it in a db friendly way more than welcome... X+ http://www.sydesy.com
Marc Boon	Friday 31 March 2006 5:49:25 am As a workaround, you could add an attribute (of type integer) to the article class which holds the number of comments. This attribute should then be incremented by template code every time a comment is posted. Then you can use attribute sorting while fetching the articles.

Paul Borgermans	Friday 31 March 2006 8:08:47 am Then write a patch for 3.8.1 ;-)) We will need this too for our internal portal: sort by the number of children and sort by the number of reverse related objects Happy coding! --paul eZ Publish, eZ Find, Solr expert consulting and training http://twitter.com/paulborgermans
Lyzy Lusterman	Tuesday 26 October 2010 9:41:51 am I like Marc's workaround suggestion... I know this is an old post, but has anyone used his suggestion successfully? I would really appreciate it if Marc, or anyone else who knows, can explain to me how I can get the integer attribute in the parent node to be edited and updated automatically whenever a child object is added. Thanks!
