From 4b37a4e8d3f93404f796a4edbfacb8b7a737c0ae Mon Sep 17 00:00:00 2001 From: Agustin Moyano Date: Wed, 19 Feb 2020 11:33:14 -0300 Subject: [PATCH] Bug 24561: Add a Datatables api wrapper that implements filter and order embedded columns This patch adds the ability to filter and order by embedded columns. To use it you must in JS: $('datatable_selector').api({datatables_options}) where datatables_options are all datatables options plus: 1. embed: [list of embeddable tables] This option adds x-koha-embed header to request. 2. header_filter: true|false This option if true sets x-koha-query header with stringyfied json of filters Oderable and searchable columns must define data option as string, otherwise filter and order won't be possible. If you must custom the output, use the render function. For example: * Don't > $('.table_selector').api({ > columns: [ > { > data: function(row, type, val, meta) { > return ''+row.holds.patron.firstname+''; > }, > orderable: true, > searchable: true > } > ] > }); * Do > $('.table_selector').api({ > columns: [ > { > data: 'holds.patron.firstname', > render: function(row, type, val, meta) { > return ''+row.holds.patron.firstname+''; > }, > orderable: true, > searchable: true > } > ] > }); To test you must implement and test bug 20936, where it will be used.
