I'm trying to add a constraint to check that two attributes have different values.
Here is my case:
class Game {
static belongsTo = [ Team ]
Team teamHome
Team teamAway
}
What I'm trying to do is somenthig like:
static constraints = {
teamHome( notEqual: teamAway )
teamAway( notEqual: teamHome )
}
How can I solve this?

You can use a validator
constraint:
static constraints = {
teamHome validator: { val, obj ->
val != obj.teamAway
}
}
The val
argument is the teamHome
value, and obj
is the object that is being validated, through which you can access the teamAway
property.
