[英]Remove a object from array using MongoDB
I am trying to remove a product from the user's cart when I delete it from the web, but I don't know how to do it.当我从 web 中删除产品时,我试图从用户的购物车中删除产品,但我不知道该怎么做。
The moongoose schema of User is the following:用户的月鹅模式如下:
var schema = mongoose.Schema({
email: { type: String, required: true },
password: { type: String, required: true },
name: { type: String, required: true },
surname: { type: String, required: true },
address: { type: String, required: true },
birth: { type: Date, required: true },
cartItems: {
type: [{
qty: { type: Number, required: true },
product: { type: mongoose.Schema.Types.ObjectId, ref: 'Product' }
}]
}
});
I want to remove an item from cartItems.我想从 cartItems 中删除一个项目。 How can I do it?
我该怎么做?
