grails create-domain-class org.bookstore.BookDatabase Mapping Usage
Domain classes in Grails by default dictate the way they are mapped to the database using sensible defaults. You can customize these with the ORM Mapping DSL. For example create a Book domain:
And then you can use the mapping block to customize the ORM mapping behavior.
package org.bookstore
class Book {
String title
Date releaseDate
Author author
static mapping = {
table "books"
author column: "auth_id"
}
}Refer to the user guide section on ORM Mapping for more information.
Global Database Mapping
You can configure mappings globally in grails-app/conf/runtime.groovy as follows:
grails.gorm.default.mapping = {
cache true
id generator: 'sequence'
'user-type'(type: org.hibernate.type.YesNoType, class: Boolean)
}
