Hello, MongoDB communities,
I have a model code as follows:
const CartSchema = new Schema({
userId: {
type: String,
required: true
},
products: [
{
productId: {
type: String
},
quantity : {
type: Number,
default: 1
},
}
]
},
{
timestamps: true,
versionKey: false,
id: true,
toJSON: {
transform(doc, ret){
ret.id = ret._id
delete ret._id
}
}
})
when I perform a request to save a cart I see _id in the products array.
I follow a discussion on stack overflow where they address to make _id: false.
Stop Mongoose from creating _id property for sub-document array items
How can I receive id instead of _id in the products array without an error message like:
document must have an _id before saving
