I'm trying to use the commandObject
to validade my data when I submit my form. Can I validate a hasMany relation in commandObject
. My cenario is something like this.
Tow simple classes
whith hasMany relationship:
class Book{
String nameBook
}
class Author{
String nameAuthor
static hasMany = [books:Book]
}
Simple commandObject
with hasMany that i want to validate when submit form.
@grails.validation.Validateable
class MyValidateCommand{
String nameAuthor
static hasMany = [books:Book]
static constraints = {
nameAuthor nullable:false
books nullable:false
}
}
Ps: I know that this commandObject is wrong, it don't compile. But can I do something like this ???
hasMany
in GORM is used for association in Domain objects. In case of command objects it will be a lucid approach to have different command objects for each domain (for example:AuthorCommand
andBookCommand
) and the command object would look like:
