如何使用ng-grid中的分组设置聚合

Question

我希望看到网格中每个组的总计(或通常是任何聚合函数).

这是请求和关闭,如问题所述:https://github.com/angular-ui/ng-grid/issues/95(但遗憾的是没有任何示例).

我可以通过配置选项重新定义默认模板https://github.com/angular-ui/ng-grid/blob/master/src/templates/aggregateTemplate.htmlaggregateTemplate.但我不知道如何正确扩展它.

此模板正在ng-grid范围内进行评估,我不知道如何触发我的自定义聚合函数.我想创建类似'''totalChildren'''的功能(来自https://github.com/angular-ui/ng-grid/blob/master/src/classes/aggregate.js)

有任何想法吗？

我找到了答案:https://github.com/angular-ui/ng-grid/issues/290

这里有一个完整的例子是我的aggredate函数:

function WorkLoadCtrl($scope, Issue, $routeParams, HttpCache) {
  $scope.issues = Issue.jql_search({jql: $routeParams.jql});

  $scope.aggFC = function (row) {
    var res = 0;

    var calculateChildren = function(cur) {
      var res = 0;
      var remaining;
      angular.forEach(cur.children, function(a) {
        remaining = a.getProperty('fields.timetracking.remainingEstimateSeconds');
        if (remaining) { res += remaining; }
      });
      return res;
    };

    var calculateAggChildren = function(cur) {
      var res = 0;
      res += calculateChildren(cur);
      angular.forEach(cur.aggChildren, function(a) {
        res += calculateAggChildren(a);
      });
      return res;
    };

    return (calculateAggChildren(row) / 3600).toFixed(2);
  }

  $scope.mySelections = [];
  $scope.gridOptions = {
    data: 'issues.issues',
    columnDefs: [
      {field:'key', displayName:'key'},
      {field:'fields.assignee.name', displayName:'Assignee'},
      {field:'fields.status.name', displayName:'Status'},
      {field:'fields.summary', displayName:'Summary'},
      {field:'fields.timetracking.remainingEstimate', displayName:'Remaining'},
    ],
    showFooter: true,
    showGroupPanel: true,
    enablePinning: true,
    enableColumnResize: true,
    enableColumnReordering: true,
    showColumnMenu: true,
    showFilter: true,
    //jqueryUIDraggable: true, bug: when used grouping stop work, but column reordering start to work:(
    selectedItems: $scope.mySelections,
    multiSelect: false,
    aggregateTemplate: '<div ng-click="row.toggleExpand()" ng-style="rowStyle(row)" class="ngAggregate"> <span class="ngAggregateText">{{row.label CUSTOM_FILTERS}} (count: {{row.totalChildren()}} {{AggItemsLabel}} Remaining: {{aggFC(row)}})</span> <div class="{{row.aggClass()}}"></div> </div>'
  };
}
