错误：Reference.push 失败：第一个参数包含属性中的函数 - firebase

Question

我正在尝试将这些值推送到我的 firebase 数据库中。当我尝试推送值时，它在控制台中出现错误（错误：Reference.push 失败：第一个参数包含属性中的函数）。我在firebase上查了一下，发现这是因为一个函数被推送了，但我根本没有推送任何函数。但我有一种感觉，这可能是因为 datetimepicker。需要帮助！

我的 JS

/*global angular*/
var app = angular.module('downtime', ['ngRoute', 'firebase']);

app.config(['$routeProvider', function ($routeProvider) {
    'use strict';
    $routeProvider.when('/downtime', {
        templateUrl: 'downtime/downtime.html',
        controller: 'downtimeCtrl'
    });
}]);

app.controller('downtimeCtrl', ['$scope', '$firebaseObject', '$firebaseArray', function ($scope, $firebaseObject, $firebaseArray) {
    'use strict';

     $scope.allEquipments = [];
     $scope.allSystems = [];

    $scope.manageDowntime = function () {

        var doesExist = false;
        angular.forEach ($scope.data , function (d) {
        angular.forEach (d.equipments, function (e) {
        })
    });
        firebase.database().ref('downtime/' + $scope.equipment + '/downtime').push({
            equipment: $scope.equipment,
            type : $scope.type,
            start: $scope.startDT,
            end: $scope.endDT
        });
};

    var ref = firebase.database().ref();
        var data = ref.child("data");
        var list = $firebaseArray(data);

        list.$loaded().then(function(data) {
            $scope.data = data;
            angular.forEach ($scope.data , function (d) {

              $scope.allSystems.push(d.$id);  

                angular.forEach (d.equipments, function (e) {
                    $scope.allEquipments.push(e.equipment);
                    console.log($scope.allEquipments);
                })
            });
            console.log($scope.data);
        }).catch(function(error) {
            $scope.error = error;
        });

    $('#datetimepicker1').datetimepicker();
    $('#datetimepicker2').datetimepicker();

}]);

app.directive('customzdatetime', function () {
    return {
        restrict: 'A',
        require: 'ngModel',
        link: function (scope, element, attrs, ngModelCtrl) {
            element.datetimepicker({
                debug: false,
                format: 'DD-MM-YYYY hh:mm'
            }).on('dp.change', function (e) {
                ngModelCtrl.$setViewValue(e.date);
                scope.$apply();
            });
        }
    };
});

firebase 将不接受日期作为数据类型，尝试将它们转换为字符串或数字，然后尝试将其推送到 firebase。我希望你的问题是 $scope.startDT 因为它包含一些函数，你试图直接使用它，这就是它抛出错误的原因，尝试将它们转换为字符串或数字，然后尝试推送。

firebase.database().ref('downtime/' + $scope.equipment + '/downtime').push({
        equipment: $scope.equipment,
        type : $scope.type,
        start: new Date($scope.startDT).toLocaleString(),
        end: new Date($scope.endDT).toLocaleString()
        or
        start: new Date($scope.startDT).getTime(), //this will get you unix timestamp as number
        end: new Date($scope.endDT).getTime()
    });
