Javascript 插入新的子文档后，如何以数组形式查找子文档？

我已经搜索了类似的案例，但在下面的代码片段中找不到问题所在

我的模式如下：

var mongoose = require('mongoose');

var teamMemberModelSchema = new mongoose.Schema({
    "email": {
        "type": String,
        "required": true,
        "min": 5,
        "max": 20
    },
    "name": {
        "type": String,
        "required": true,
        "min": 5,
        "max": 20
    },
    "role": {
        "type": String,
        "required": true,
        "min": 20,
        "max": 50
    },
    "twitter": {
        "type": String,
        "required": true,
        "min": 20,
        "max": 50
    },
    "facebook": {
        "type": String,
        "required": true,
        "min": 20,
        "max": 50
    },
    "linkedin": {
        "type": String,
        "required": true,
        "min": 20,
        "max": 50
    },
});

var teamModelSchema = new mongoose.Schema({
    "title": {
        "type": String,
        "required": true,
        "min": 5,
        "max": 20
    },
    "headline": {
        "type": String,
        "required": true,
        "min": 5,
        "max": 30
    },
    "description": {
        "type": String,
        "required": true,
        "min": 5,
        "max": 80
    },
    "members": [teamMemberModelSchema]
}, { collection: 'team' });

teamModelSchema.set('collection', 'team');
mongoose.model('team', teamModelSchema);
mongoose.model('member', teamMemberModelSchema);

问题在于尝试向teamModelSchema内的members数组添加新项

它返回“TypeError:无法读取未定义的属性“push”

我试过几种不同的方法，但都没有达到预期的效果

在这种情况下，如何向成员添加新项目

PS:sendJsonResponse只是一个不执行res status和json对象的函数

find（）

返回文档数组

teamInfo

变量为数组

数组编号包含

成员

属性

---

使用

findOne

获取特定文档或按索引从数组中选择特定文档（例如

teamInfo[0].members.push

）。

@Lemix。在了解了您的帮助并尝试了一段时间后，有效的解决方案如下：

module.exports.addTeamMember = function (req, res) {

    TeamModel.find( TeamModel ).exec(
        function (err, teamInfo) {
            if (err) {
                responseUtilities.sendJsonResponse(res, err, teamInfo);
            } else {

                teamInfo[0].members.push({
                    email: req.body.email,
                    name: req.body.name,
                    role: req.body.role,
                    twitter: req.body.twitter,
                    facebook: req.body.facebook,
                    linkedin: req.body.linkedin
                });

                var membersLength = teamInfo[0].members.length - 1;
                var thisMember;
                thisMember = teamInfo[0].members[membersLength];

                var doc  = { id: teamInfo[0].description.id };
                var options = { $set: { id: teamInfo[0].id,
                                        description: teamInfo[0].description,
                                        headline: teamInfo[0].headline,
                                        title: teamInfo[0].title,
                                        members: teamInfo[0].members,
                                        }};

                 TeamModel.updateOne(doc, options,function (err, teamInfo) {
                    if (err) {
                        data = teamInfo;
                    }
                    else {
                        data = thisMember;
                    }
                    responseUtilities.sendJsonResponse(res, err, data);
                 }
                )};
            }
        );
};

你能分享收集的数据吗你好，看看我找到的解决方案。成功了。你怎么认为？有没有办法使它更简单？

module.exports.addTeamMember = function (req, res) {

    TeamModel.find( TeamModel ).exec(
        function (err, teamInfo) {
            if (err) {
                responseUtilities.sendJsonResponse(res, err, teamInfo);
            } else {

                teamInfo[0].members.push({
                    email: req.body.email,
                    name: req.body.name,
                    role: req.body.role,

                    linkedin: req.body.linkedin
                });

                var membersLength = teamInfo[0].members.length - 1;
                var thisMember;
                thisMember = teamInfo[0].members[membersLength];

                var doc  = { id: teamInfo[0].description.id };
                var options = { $set: { id: teamInfo[0].id,
                                        description: teamInfo[0].description,
                                        headline: teamInfo[0].headline,
                                        title: teamInfo[0].title,
                                        members: teamInfo[0].members,
                                        }};

                 TeamModel.updateOne(doc, options,function (err, teamInfo) {
                    if (err) {
                        data = teamInfo;
                    }
                    else {
                        data = thisMember;
                    }
                    responseUtilities.sendJsonResponse(res, err, data);
                 }
                )};
            }
        );
};
