As I create the Models to define the real-world things of interest to
my webapp, I'm wondering what to put into either the class or the
object. Here is some pseudocode as I understand the Model table
definition pattern:
// first comes the class, which defines fields and creates the
singleton:
class Thing extends LongKeyedMapper[Thing] with IdPK {
def getSingleton = Thing
// define a field...
object field extends mappedWhatever(this) {
// and define some constraints and validations for the field...
}
// global class methods here plus xml, json, etc output...
}
// then the object:
object Thing extends Thing with LongKeyedMetaMapper[Thing] {
// define an instance method:
def instanceMethod() = {
doSomething
}
// more instance methods, etc...
}
My question is: how do I know what kinds of methods and other goodies
should go into either the class or the object, that is, into each
'half' of the Model specification?
