Post model
const Schema = mongoose.Schema;
const postSchema = new Schema({
title: { type: String, required: true },
content: { type: String, required: true },
user: { type: Schema.Types.ObjectId, ref: "User" },

endpoint for getting all posts with all users information
listPostsWithUsers: (req, res, next) => {
Post.find({}, (error, posts) => {
if (error) {
return res.status(500).json({ error: "something went wrong" })
} else if (!posts) {
return res.status(400).json({ msg: "sorry no posts" })
} else if (posts) {
return res.status(200).json({ posts })
}
})
}
Выводом должны быть возвращенные сообщения с объектом пользователя, чтобы я мог определить, какое сообщение опубликовал пользователь.
Теперь мой вопрос: как мне применить * 1022? * метод в вышеуказанной конечной точке. В основном все примеры с функцией exec()
, но я не видел ни одного примера с обратными вызовами. Это своего рода синтаксическая проблема.
Спасибо.
