From 9a3c9371f39b2c063a1750df9d7cd4c6970791cc Mon Sep 17 00:00:00 2001 From: Agustin Moyano Date: Wed, 19 Feb 2020 11:33:14 -0300 Subject: [PATCH] Bug 24561: Datatables api wrapper also 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 > $('.table_selector').api({ > columns: [ > { > data: 'holds.patron.firstname', > render: function(row, type, val, meta) { > return ''+row.holds.patron.firstname+''; > }, > orderable: true, > searchable: true > } > ] > }); To test you must implement and test bug 20936, where it will be used. --- koha-tmpl/intranet-tmpl/prog/js/datatables.js | 92 +++++++++++++++++++ .../opac-tmpl/bootstrap/js/datatables.js | 92 +++++++++++++++++++ 2 files changed, 184 insertions(+) diff --git a/koha-tmpl/intranet-tmpl/prog/js/datatables.js b/koha-tmpl/intranet-tmpl/prog/js/datatables.js index a31db0614d..77804eca3b 100644 --- a/koha-tmpl/intranet-tmpl/prog/js/datatables.js +++ b/koha-tmpl/intranet-tmpl/prog/js/datatables.js @@ -502,3 +502,95 @@ function filterDataTable( table, column, term ){ table.search( term ).draw("page"); } } + +jQuery.fn.dataTable.ext.errMode = function(settings, note, message) { + console.warn(message); +}; + +(function($) { + + $.fn.api = function(options) { + var settings = null; + if(options) { + settings = $.extend(true, {}, dataTablesDefaults, { + 'deferRender': true, + "paging": true, + 'serverSide': true, + 'searching': true, + 'pagingType': 'full', + 'ajax': { + 'type': 'GET', + 'cache': true, + 'dataSrc': 'data', + 'beforeSend': function(xhr, settings) { + this._xhr = xhr; + if(options.embed) { + xhr.setRequestHeader('x-koha-embed', Array.isArray(options.embed)?options.embed.join(','):options.embed); + } + if(options.header_filter && options.query_parameters) { + xhr.setRequestHeader('x-koha-query', options.query_parameters); + delete options.query_parameters; + } + }, + 'dataFilter': function(data, type) { + var json = {data: JSON.parse(data)}; + if(total = this._xhr.getResponseHeader('x-total-count')) { + json.recordsTotal = total; + json.recordsFiltered = total; + } + return JSON.stringify(json); + }, + 'data': function( data, settings ) { + var length = data.length; + var start = data.start; + + var dataSet = { + _page: Math.floor(start/length) + 1, + _per_page: length + }; + + var filter = data.search.value; + if (filter != '') { + var query_parameters = settings.aoColumns + .filter(function(col) { + return col.bSearchable && typeof col.data == 'string' + }) + .map(function(col) { + var part = {}; + part[!col.data.includes('.')?'me.'+col.data:col.data] = {like: filter+'%'}; + return part; + }); + + if(query_parameters.length) { + query_parameters = JSON.stringify(query_parameters.length === 1?query_parameters[0]:query_parameters); + if(options.header_filter) { + options.query_parameters = query_parameters; + } else { + dataSet.q = query_parameters; + } + } + + dataSet._match = 'starts_with'; + } else { + delete options.query_parameters; + } + + if(options.columns) { + var order = data.order; + order.forEach(function (e,i) { + var order_col = e.column; + var order_by = options.columns[order_col].data; + var order_dir = e.dir == 'asc' ?
