Grails Domain Object Includes Class Attribute

I'm using a domain object to interface with a database in Grails.

When I use the list() method on a domain object to get all of the rows from a database it works great except for one thing. The object that comes back for each row also includes an attribute called "class". I've read some things about creating a custom marshaller that would allow me to remove that attribute from the object. Is that really the best way to not have to return the class attribute?

Thanks!

Are you seeing the class in the actual database record or are you talking about when you render it as JSON? - Joshua Moore

You can also use JSON.registerObjectMarshaller as below:

// BootStrap.groovy
JSON.registerObjectMarshaller( YourDomain ) {
    it.properties.findAll { it.name != 'class' }
}

Refer here for a similar example.

Here's a link to change the way Grails renders JSON by default: http://grails.org/doc/2.4.4/guide/single.html#defaultRenderers

Just change "NameOfDomainClass" to the class you want to render differently. In this case, the Domain Class. 

import grails.rest.render.json.*
beans = {
    bookRenderer(JsonRenderer, NameOfClass) {
        excludes = ['class']
    }
}
