Question

以下是我的架构

var mongoose = require("mongoose");

var messageSchema = mongoose.Schema({
    text: { type: String, required: true },
    author: {
        id: {
            type: mongoose.Schema.Types.ObjectId,
            ref: "User"
        },
        name: { type: String, required: true }
    }
});

module.exports = mongoose.model("Message", messageSchema);

我的用户架构

var mongoose = require("mongoose");
var passportLocalMongoose = require("passport-local-mongoose");
var uniqueValidator = require('mongoose-unique-validator');

var UserSchema = mongoose.Schema({
    username: { type: String, required: true, unique: true },
    password: { type: String, required: true },
    first_name: { type: String, required: true },
    middle_initial: { type: String, required: true },
    last_name: { type: String, required: true },
    phone: { type: Number, required: true },
    address: { type: String, required: true },
    email: { type: String, required: true, unique: true },
    isManager: Boolean,
    isSysAdmin: Boolean,
    points_accrued: Number,
    messages: [
        {
            type: mongoose.Schema.Types.ObjectId,
            ref: "Message"
        }
    ],
    id: {
        type: mongoose.Schema.Types.ObjectId,
        ref: "User"
    }
});

UserSchema.plugin(passportLocalMongoose);
UserSchema.plugin(uniqueValidator);

module.exports = mongoose.model("User", UserSchema);

然后这是我的路线

// Gets messages for regular Employees, not Admins
router.get("/messages", middleware.isLoggedIn, function (req, res) {
    User.find({}).populate("message").exec(function (err, foundUsers) {
        if (err || !foundUsers) {
            req.flash("error", "Users Not Found");
            res.redirect("back");
        } else {
            res.render("users/messages", { users: foundUsers });
        }
    });
})

//================//
// POST A MESSAGE //
//================//

router.post("/messages", middleware.isLoggedIn, function (req, res) {
    User.findOne({ username: req.body.reciever }, (err, foundUser) => {
        if (err) {
            res.redirect("back")
        } else {
            const newMessage = {
                text: req.body.message,
                author: {
                    id: req.user._id,
                    name: req.user.first_name + " " + req.user.middle_initial + " " + req.user.last_name
                }
            }
            Message.create(newMessage, (err, newMessage) => {
                if (err) {
                    req.flash("error", "Whoops! Something went wrong...");
                    console.log(err);
                    res.redirect("/users/messages");
                } else {
                    User.findOneAndUpdate({ username: req.body.reciever }, { $push: { messages: newMessage._id } }, (err, updateData) => {
                        req.flash("success", "Message Sent!");
                        res.redirect("/users/messages");
                    })
                }
            })
        }
    })
})

最后，这是我的ejs文件

<div class="container">
     <% user.messages.forEach(function(message){ %>
     <% console.log(message.author); %>
          <p>
              <%= message %>
          </p>
     <% }); %>
 </div>

因此ID正在显示消息，但我无法访问作者信息或文本。 ejs文件中的console.log（）返回undefined。我的数据库中的数据是正确的，并显示所有信息。我试过.populate（{路径：＆＃34;消息＆＃34;}），但即使这样也行不通。谢谢！

模式和模型工作正常，但.populate（）被破坏了
