Grails y sus clases GORM Saludos Amigos necesito su ayuda, la verdad estoy leyendo un libro para aprender grails, tengo estas 2 clases
class Telas {
static searchable = true
String numorden
String proveedor
String descripcion
String color
Date dateCreated
Date lastUpdated
static hasMany = [kardex:Kardex]
static constraints = {
numorden (blank:false, maxSize:5)
}
//Auditoria
def beforeInsert() {
dateCreated = new Date()
}
def beforeUpdate() {
lastUpdated = new Date()
}
String toString(){
return numorden
}
}
class Kardex {
static searchable = true
Date fecha
String descripcion
int ingreso
int egreso
static belongsTo = [telas:Telas]
}
Y quiero poner
def telas = Telas.count()
Supongo que esto me devolvera cuantos registros existen en la tabla telas pero me da este error y no me funciona ningun metodo.
No se como puedo hacer para que funcionen los comandos para hacer un select o estos metodos van dentro de las clases o en los controladores.
