Rally 从看板上筛选史诗

首先，我想说我已经读过了，但是我仍然无法根据Estimation Board应用程序的过滤过程来实现我的过滤。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。查询对象调用此函数。\ u getItems返回要从中筛选的项目数组。据我所知，查询调用函数，加载一两秒钟，然后不显示结果。欢迎任何意见、建议或替代解决方案

这是我的密码

$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);

                            }

不确定这是您的问题，但您的纸板配置没有设置“查询”字段。fetch是要检索的所有数据的类型，如果要在向config对象添加query:value时对其进行筛选。 比如：

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

---

其中，可以使用Rally query对象构造fullQuery。您可以通过在SDK中搜索来找到它。希望这可能会有所帮助。

Per'提示

以下是我是如何按照Charles对拉力赛目录看板的提示来处理这个问题的。首先，修改cardboardConfig中的fetch语句，使其包含子集合，从而：

      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);   

     cardboard.display("kanbanBoard");

本声明：

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

     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
        }
    );

调用carboard.setItemsfilteredItems时，Mark的回答导致了一个模糊的崩溃。然而，由于过滤代码实际上是在操作实际引用，因此实际上并不需要setItems方法。我把它拔了出来，现在它可以正常过滤了。

fullQuery应该用引号括起来吗？当我按原样添加查询时，看板板无法显示。当我添加引号时，它会加载，但仍然不会产生响应。fullQuery应该在引号中吗？当我按原样添加查询时，看板板无法显示。当我添加引号时，它会加载，但仍然没有响应。非常感谢，这让我开始发疯了！非常感谢你，这让我开始发疯了！我不确定将此标记为答案是否是适当的堆栈溢出礼节，但我还没有足够的重复投票，所以请继续。我不确定将此标记为答案是否是适当的堆栈溢出礼节，但我还没有足够的重复投票，所以请继续。
