Question

Im using grails 1.3.7 and here is the case…
Have a huge form with a few different prefixes for its fields (later used in data binding) and trying to validate thru a command object… however the lovely DOT used in prefixes is giving me a hard time and cannot get the names mapped properly in command object… any suggestion please?

in the form have fields like field like this one:

<input name="dealer.name" value="${dealer.name}" type="text"> 

and for command object:

class somethingCommand {
    String name
    Map dealer = [:]
    static constraints = {
        dealer validator: {
            val, obj ->
            obj.properties["name"] != ""
        }
    }
}

what if…. we look at it in another way and map the parameters before passing to command object… how should I pass my parameters to a command object without using grails magic?!?!?!

tnx

Answer 1

you could grab the “dealer” map in the controller via

def dealerMap = params["dealer"]

and then create a dealer command opject by hand and bind the map content to it.

def dealerCommand = new DealerCommand() 
bindData(dealerCommand , dealerMap)

you can then use the validation of the command object as normal
