Map domain class with predifined values to table

Is it possible to create domain class which will开发者_开发问答 be mapped to db table with predefined values, for example:

id value

1 test1

2 test2

3 test3

Or I have to manualy edit generated *.sql file to acomplish this?

Thanks in advance.

One way to have a static set of predefined rows in a table is to populate it in BootStrap.groovy. For example:

def init = { servletContext ->
    if (MyDomain.count() == 0) {
        new MyDomain(id: 1, value: 'test1').save(failOnError: true)
        new MyDomain(id: 2, value: 'test2').save(failOnError: true)
        new MyDomain(id: 3, value: 'test3').save(failOnError: true)
    }
}

Another approach would be to use the migrations plugin and create a database migration to populate the table.
