MongoDB/猫鼬填充
问题描述:
使用猫鼬"填充"-到目前为止,我无法成功获得食物"模型填充用户"模型.
Working with Mongoose "Populate" - So far I'm unable to successfully get the "Food" model to populate the "User" model.
目标是能够为用户保存食物".
用户模型:
var UserSchema = new mongoose.Schema({
username: String,
password: String,
foods: [{ type: mongoose.Schema.Types.ObjectId}],
easy: {type: Boolean, default: false},
});
UserSchema.plugin(passportLocalMongoose)
module.exports = mongoose.model("User", UserSchema);
食物模型:
var foodSchema = new mongoose.Schema({
name: { type: String, required: false, unique: true },
author: {
id: {
type: mongoose.Schema.Types.ObjectId,
ref: "User",
},
}
});
module.exports = mongoose.model("Food", foodSchema);
获取路线
router.get("/dashboard", function (req, res) {
User.find({currentUser: req.user})
.populate({path: 'foods'}).
exec(function (err, foods) {
if (err) return (err);
console.log('The food is:', req.user.foods.name);
});
});
发布路线:
router.post("/dashboard", function(req, res, next) {
User.update({ id: req.session.passport.user }, {
}, function(err, user) {
if (err) return next(err);
User.findById(req.user._id, function(err, user) {
var newFood = new Food({
name: req.body.currentBreakfast,
image: 'test',
});
user.foods = newFood
user.save();
});
});
res.redirect('/dashboard');
});
答
您可以使用此查询.
await User.find({currentUser: req.user}).populate('foods')
