$omit

Update records by removing specific properties from an object field in the specified column. The $omit method is used to exclude certain properties from an object, creating a new object without the specified keys. For example, if you have an object like { name: "John", age: 30, country: "USA" } and use $omit: "<objectName>.age", the result would be { name: "John", country: "USA" }. This is useful when you want to update or store only a subset of an object’s properties, excluding sensitive or unnecessary data.

await Member.$update({
    $where: { 
        age: { 
            $eq: 16 
        } 
    },
    $update: {
        $omit: {
            'logins.ip': 'ip'
        }
    }
});
