Question

我有一个如下所示的对象结构

$(document).ready(function () {


    // Select all
    $('#selecctall').click(function (event) { //on click 
        if (this.checked) { // check select status
            $('.checkbox1').each(function () { //loop through each checkbox
                this.checked = true; //select all checkboxes with class "checkbox1"               
            });
        } else {
            $('.checkbox1').each(function () { //loop through each checkbox
                this.checked = false; //deselect all checkboxes with class "checkbox1"                       
            });
        }
    });

});

//Addition for checked value
$('input').click(function () {
    var sum = 0;
    $('input[type=checkbox]:checked').each(function () {
        sum += Number($(this).val());
    });
    console.log(sum);
    $("#sum").html(sum);
});

//popover
$(document).ready(function () {
    $('.pop').popover({
        content: "Other Expenses 200 <br> Other Expenses 200 <br>Other Expenses 200 <br> ",
        html: true,
        placement: "right",
        trigger: "focus"
    });
});

我需要总结（至少检索）＆＃34; generated_capacity＆＃34; ＆＃34; wind_data＆＃34;中的所有对象有＆＃34; date＆＃34;等于＆＃34; 16-08-15＆＃34; ＆＃34; TOTAL＆＃34;宾语。我试过这个查询

但是，此查询无效。请提出一些解决方法。

以下查询可以完成工作

    db.collectionName.aggregate([      
      {"$unwind":"$wind_data"},       
      {"$match":{"plant_name":"TOTAL","wind_data.date":"16-08-15"}},
      {"$group":{"_id":"$wind_data.date","generated_capacity_sum":{"$sum":"$wind_data.generated_capacity"}}}
    ])
