Mongo embedded object vs. map?

[Robert La Ferla]

I want to store an embedded object (not a reference to another collection) in a Mongo domain class..

Let's say this record is in the database:

{
        firstName: "John",
        lastName: "Smith",
        salaryRange: { min: 70000, max: 90000, desc: "something"}
}


class Employee {
        String firstName;
        String lastName;
        Map salaryRange;  // ????????????
}

I do not want salaryRange in a separate collection but is there a way to use a class instead of a generic Map for this mapping?

Thanks in advance!

You can create a new domain class, SalaryRange:

class SalaryRange {

    int min
    int max
    String descr

    static constraints = {
        // whatever constraints you need
    }
}

Then declare SalaryRange to be embedded in your Employee class:

class Employee {

    String firstName
    String lastName
    SalaryRange salrange

    static embedded = ['salrange']

    static constraints = {
        // whatever constraints you need
    }
}

With this there will be only one collection, Employee, each document in that collection will have embedded SalaryRange data.

Good luck,
David
