angularjs - 如何在 ng-grid 中使用分组设置聚合

Question

我想查看网格中每个组的总数(或通常的任何聚合函数)。

这是在问题中请求并关闭的:https://github.com/angular-ui/ng-grid/issues/95 (但不幸的是没有任何例子)。

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

此模板正在 ng-grid 范围内评估，我不知道如何触发我的自定义聚合函数。我想创建与 '''totalChildren''' 类似的函数(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

对于完整的这里是我的聚合函数的一个例子:

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>'
  };
}
