Question

我接近拥有一个有效的网络应用程序。 Mongoose正在发送我的数据 mongolab如果我在平面架构中有它没有问题。当我尝试将它安排成更容易管理的东西，它作为一个空的到来阵列（一个或多个）。我尝试过几种不同的架构设计结果。我没有做任何过于花哨的事情。我看着对方这里的帖子与空数组有关，但我唯一不能做的事情弄清楚是通过submit（）我的XHR请求发送数据时：

分辨

在我们开始之前，这对你来说可能无法正常工作，因为我使用平均堆栈以不同的方式完成所有导出操作。但是如何嵌入数组的原则仍应有效。

休息后吃点东西。我已更新原始帖子，以反映我在控制器和架构中的当前代码。我会在数据库中显示它的样子。对于任何想要在数组中放置数组的人来说：

在控制器内或您将表单数据绑定到文档的位置创建一个空数组，因此：

var followupDetails = [];

创建一个对象来表示要嵌入的数据（数组进入对象）

        var followup = {
            followup: [{
                technicianName: this.technicianName,
                consultationStatus: this.consultationStatus,
                followUpDate: this.followUpDate,
                followUpNotes: this.followUpNotes,
                installDate: this.installDate,
                technicianCellPhone: this.technicianCellPhone
            }]
        };

将对象推入空数组，因此：

followupDetails.push（后续）;

将该属性添加到要将数组嵌入的现有对象中。我被称为咨询，我用followupDetails数组的值创建了一个 followup 属性。

consult.followup = followupDetails;

你不得不将它添加到创建文档的$ scope.create函数中，该函数将通过模式传递。它是在编译它的父级时创建的。即。

var ConsultationSchema = new Schema({
    "consultation":{
        "customerDetails": [customerDetailsSchema],
        "currentSystem": [currentSystemSchema],
        // followups in now inside the consultDetails
        "consultDetails": [consultDetailSchema]
    }
});

其他一切都完全一样。另请注意，我的后续生活咨询模式现在与以前相同：

var consultDetailSchema = new Schema({
    ...
    ...
    followup:[followupSchema]
});

这是我整理的完整架构

mongoose.model('Consultation', ConsultationSchema);

这里的控制器，记得当你点击提交时它应该运行create（）函数在实例化模型的新实例之前执行在create函数体内构建文档的代码：

'use strict';

// Consultations controller
angular.module('consultations')
    .controller('ConsultationsController', ['$scope', '$stateParams', '$location', 'Authentication', 'Consultations',

    function($scope, $stateParams, $location, Authentication, Consultations) {
        $scope.authentication = Authentication;

        // Create new Consultation
        $scope.create = function() {

        var customerDetails = [];
        var systemDetails = [];
        var consultDetails = [];
        var followupDetails = [];

        var customer = {
            customerName: this.customerName,
            customerAddress: this.customerAddress,
            customerCity: this.customerCity,
            customerState: this.customerState,
            customerZipCode: this.customerZipCode,
            customerHomePhone: this.customerHomePhone,
            customerCellPhone: this.customerCellPhone,
            customerEmail: this.customerEmail,
            comporiumId: this.comporiumId
        };

        var system = {
            systemType: this.systemType,
            systemOther: this.systemOther,
            systemMonitored: this.systemMonitored,
            deluxePhonePackage: this.deluxePhonePackage
        };

        var followup = {
            followup: [{
                technicianName: this.technicianName,
                consultationStatus: this.consultationStatus,
                followUpDate: this.followUpDate,
                followUpNotes: this.followUpNotes,
                installDate: this.installDate,
                technicianCellPhone: this.technicianCellPhone
            }]
        };

        var consult = {
            consultComments: this.consultComments,
            consultantName: this.consultantName,
            technician: this.technician,
            scheduleDate: this.scheduleDate,
            created: this.created,
            user: this.user
        };

        customerDetails.push(customer);
        systemDetails.push(system);
        followupDetails.push(followup);
        consultDetails.push(consult);

        consult.followup = followupDetails;

            // Create new Consultation object
            var consultation = new Consultations ({
                consultation:{
                    customerDetails: customerDetails,
                    currentSystem: systemDetails,
                    consultDetails: consultDetails,
                }
            });

所以这就是我最初得到的：

{
    "_id": {
        "$oid": "556daad4da83801971345211"
    },
    "consultation": {
        "consultDetails": [],
        "currentSystem": [],
        "customerDetails": []
    },
    "__v": 0
}

现在看来，db中没有传递数据，因为我只是单击“创建”而不是填充任何内容：

    "_id": {
        "$oid": "556e479f9695f6c804de0a7f"
    },
    "consultation": {
        "consultDetails": [

                },
                "followup": [
                    {

Mongoose并没有将一种数据格式神奇地转换为您的架构格式。你需要自己做。它只是在对象上强制执行您的架构。由于您的所有文档都没有required option且您不是strictly enforcing the schema，因此您实际上是在创建一个空文档（默认情况下会返回空的suddoc数组）。

因此，您需要更新处理发布请求的任何方法，以将请求post对象格式化为正确的格式以匹配您的Mongoose架构。您还可以将架构选项strict设置为抛出而不是忽略（默认值），以确保您不会尝试向文档添加无效属性。之后，您应该能够检索非空文档。
