(Quick Reference)
validate
Purpose
Validates a domain class against the applied constraints (see
Validation)
Description
The
validate
method validates a domain class based on its defined
constraints. The errors are stored in the
errors property of the domain class instance.
The
validate
method accepts an optional
List
argument which contains the names of the properties to be validated. When a
List
of names is specified, only those properties will be validated.
Examples
def b = new Book(title: "The Shining")
if (!b.validate()) {
b.errors.each {
println it
}
}
def a = new Album(artist: "Genesis", title: "Nursery Cryme", releaseDate: 1971)// only validate title and releaseDate
if (!a.validate(["title", "releaseDate"])) {
a.errors.each {
println it
}
}
Parameters:
deepValidate
(optional) - Whether associations of the domain instance should also be validated, i.e. whether validation cascades. This is true
by default; set it to false
to disable cascading validation.
