Validation with min option-CodePudding

I have mongoose schema with field validate option min:

export const CartSchema = new Schema<ICartSchema>({
    amount: {
        type: Number,
        default: 1,
        min: 1
    }
}, { versionKey: false });

when i try update my document and set value <1, i didnt get some error and document get value <1

 switch (type) {
                case "inc": {
                    update = { $inc: { amount: 1 } }
                    break;
                }
                case "dec": {
                    update = { $inc: { amount: -1 } }
                    break;
                }
                default: throw Error("Bad request");
            }

            const cart = await Cart.findOneAndUpdate({ _id: cartId }, update,
                {
                    new: true,
                    runValidators: true
                }).populate({
                    path: "product",
                    select: {
                        user: 0
                    }
                });

mongoose version ^6.0.7

CodePudding user response：

As docs says:

One final detail worth noting: update validators only run on the following update operators:

$set

$unset

$push (>= 4.8.0)

$addToSet (>= 4.8.0)

$pull (>= 4.12.0)

$pullAll (>= 4.12.0)

Even the uses $inc as example where validators doesn't work:

For instance, the below update will succeed, regardless of the value of number, because update validators ignore $inc.
