我想首先说我已经阅读了Rally Kanban - 隐藏 Epic Stories，但我仍然无法根据 Estimation Board 应用程序中的过滤器流程来实施过滤器。目前我正在尝试为我的纸板添加一个项目过滤器到我的查询对象中。查询对象调用 this._getItems 以返回要从中过滤的项目数组。据我所知，查询调用了函数，加载了一两秒钟，然后没有显示任何结果。欢迎任何意见、建议或替代解决方案。

这是我的代码

$that._redisplayBoard = function() {


            that._getAndStorePrefData(displayBoard);

            this._getItems = function(callback) {

            //Build types based on checkbox selections
            var queries = [];

                    queries.push({key:"HierarchicalRequirement",
                        type: "HierarchicalRequirement",
                        fetch: "Name,FormattedID,Owner,ObjectID,Rank,PlanEstimate,Children,Ready,Blocked",
                        order: "Rank"

                    });



            function bucketItems(results) {
                var items = [];

                rally.forEach(queries, function(query) {
                    if (results[query.key]) {
                        rally.forEach(results[query.key], function(item) {
                            //exclude epic stories since estimates cannot be altered
                            if ((item._type !== 'HierarchicalRequirement') ||
                                    (item._type === 'HierarchicalRequirement' && item.Children.length === 0)) {
                                items = items.concat(item);

                            }
                        });
      }
                });


               callback(items);
                }

                 rallyDataSource.findAll(queries, bucketItems);

            };

            function displayBoard() {

                artifactTypes = [];



                var cardboardConfig = {

                    types: [],

                    items: that._getItems,

                    attribute: kanbanField,

                    sortAscending: true,

                    maxCardsPerColumn: 200,

                    order: "Rank",

                    cardRenderer: KanbanCardRenderer,

                    cardOptions: {

                        showAgeAfter: showAgeAfter

                    },

                    columnRenderer: KanbanColumnRenderer,

                    columns: columns,

                    fetch: "Name,FormattedID,Owner,ObjectID,Rank,Ready,Blocked,LastUpdateDate,Tags,State,Priority,StoryType,Children"

                };



                if (showTaskCompletion) {

                    cardboardConfig.fetch += ",Tasks";

                }



                if (hideLastColumnIfReleased) {

                    cardboardConfig.query = new rally.sdk.util.Query("Release = null").or(kanbanField + " != " + '"' + lastState + '"');

                }



                if (filterByTagsDropdown && filterByTagsDropdown.getDisplayedValue()) {

                    cardboardConfig.cardOptions.filterBy = { field: FILTER_FIELD, value: filterByTagsDropdown.getDisplayedValue() };

                }



                cardboardConfig.types.push("HierarchicalRequirement");



                if (cardboard) {

                    cardboard.destroy();

                }



                artifactTypes = cardboardConfig.types;






                cardboard = new rally.sdk.ui.CardBoard(cardboardConfig, rallyDataSource);




                cardboard.addEventListener("preUpdate", that._onBeforeItemUpdated); 
                cardboard.addEventListener("onDataRetrieved", function(cardboard,args){ console.log(args.items); }); 

                cardboard.display("kanbanBoard");

            }

        };


        that.display = function(element) {



            //Build app layout

            this._createLayout(element);



            //Redisplay the board

            this._redisplayBoard();

        };

    };

根据查尔斯在拉力赛看板中的暗示- 隐藏史诗故事

以下是我在查尔斯对拉力赛目录看板的提示之后处理这个问题的方法。首先，修改 cardboardConfig 中的 fetch 语句，使其包含 Children 集合，因此：

      fetch: "Name,FormattedID,Children,Owner,ObjectID,Rank,Ready,Blocked,LastUpdateDate,Tags,State"

接下来，在这句话之间：

      cardboard.addEventListener("preUpdate", that._onBeforeItemUpdated);

而这个声明：

     cardboard.display("kanbanBoard");

添加以下事件侦听器和回调：

    cardboard.addEventListener("onDataRetrieved", 
        function(cardboard, args){
            // Grab items hash
            filteredItems = args.items;

            // loop through hash keys (states)
            for (var key in filteredItems) {

                // Grab the workproducts objects (Stories, defects)                 
                workproducts = filteredItems[key];
                // Array to hold filtered results, childless work products
                childlessWorkProducts = new Array();
                // loop through 'em and filter for the childless
                for (i=0;i<workproducts.length;i++) {
                    thisWorkProduct = workproducts[i];                      
                    // Check first if it's a User Story, since Defects don't have children
                    if (thisWorkProduct._type == "HierarchicalRequirement") {
                        if (thisWorkProduct.Children.length === 0 ) {
                            childlessWorkProducts.push(thisWorkProduct);
                        }
                    } else {
                        // If it's a Defect, it has no children so push it
                        childlessWorkProducts.push(thisWorkProduct);
                    } 
                }
                filteredItems[key] = childlessWorkProducts;
            }
            // un-necessary call to cardboard.setItems() was here - removed
        }
    );

此回调应仅过滤叶节点项。

不确定这是您的问题，但您的纸板配置未设置“查询”字段。如果要过滤它，则 fetch 是要检索的所有数据的类型，您可以向配置对象添加“查询：”值。就像是 ：

        var cardboardConfig = {
         types: ["PortfolioItem", "HierarchicalRequirement", "Feature"],
         attribute: dropdownAttribute,
         fetch:"Name,FormattedID,Owner,ObjectID,ClassofService",
         query : fullQuery,
         cardRenderer: PriorityCardRenderer
    };

可以使用 Rally 查询对象构造 fullQuery。您可以通过在 SDK 中搜索找到它。希望这可能会有所帮助。

调用 cardboard.setItems(filteredItems) 时，Mark 的回答导致了一次不明显的崩溃。但是，由于过滤代码实际上是在操作实际的引用，因此实际上不需要 setItems() 方法。我把它拔了出来，它现在可以正常过滤了。
