Question

我有一张动态的票证状态。每张票可以处于状态＆＃34; 处理中＆＃34;并且有不同的＆＃34; this.statusStack.currentStatus ＆＃34;值。

下一个代码（不起作用）试图解释我尝试做什么

var tickets = Tickets.find({
  driverAsigned: Meteor.userId(),
  'statusStack.stack.(this.statusStack.currentStatus).name': "In Process"
});

*****新数据******

我的意思＆＃34; this.statusStack.currentStatus ＆＃34;是一个内部文档值，而不是我的代码的变量。

这是票证的结构

{
......
"statusStack" : {
    "stack" : [
        {
            "sortable" : false,
            "removable" : false,
            "order" : 0,
            "name" : "Draft",
            "customName" : "Draft",
            "description" : "When the ticket has been created",
            "color" : "#4d4d4d"
        },
        {
            "sortable" : false,
            "removable" : false,
            "order" : 1,
            "name" : "New",
            "customName" : "New",
            "description" : "When the ticket info has been updated",
            "color" : "#f4f93e"
        },
        {
            "sortable" : true,
            "removable" : false,
            "order" : 2,
            "name" : "Assigned",
            "customName" : "Assigned",
            "description" : "When the ticket info has been asigned to a driver",
            "color" : "#3e89f9"
        },
        {
            "sortable" : true,
            "removable" : false,
            "order" : 3,
            "name" : "In Process",
            "customName" : "In Process",
            "description" : "When the ticket has been created",
            "color" : "#f0883c"
        },
        {
            "sortable" : true,
            "removable" : true,
            "order" : 4,
            "name" : "Frodo",
            "customName" : "Blank",
            "description" : "New Blank Status",
            "color" : "#4d4d4d"
        },
        {
            "sortable" : true,
            "removable" : false,
            "order" : 5,
            "name" : "Resolved",
            "customName" : "Resolved",
            "description" : "When the Driver has resolved the Ticket",
            "color" : "#42f93e"
        },
        {
            "sortable" : false,
            "removable" : false,
            "order" : 6,
            "name" : "Closed",
            "customName" : "Closed",
            "description" : "When the Admin has been closed the Ticket",
            "color" : "#217b1f"
        }
    ],
    "currentStatus" : 5
},
......
}

Sudo Code：

获取数组元素位置优先。

pos = statusStack.currentStatus
然后您可以使用该pos（int）变量来构建查询文档

var query = tojson（＆＃39; {＆＃34; statusStack.stack。＆＃39; + pos＆＃39; +＆＃39; .name＆＃34;：＆＃34; In Process＆＃34; }＆＃39）;

在查找中使用该查询文档。

MongoDB通过动态查询第N个元素来获取数据集合
