Using custom constraints

[Thomas Buckley]

Hi

I nealy have my form valadting client side based on my command object constrainst.

There is one problem, I have a custom constraint in my command object:

startTime(nullable: false, validator: {startTime, deal ->

if ((!DateUtils.isSameDay(startTime, new Date()) && startTime.before(new Date()))) //Start date is today or future but not before end date

{

return "pastDate"

}

if (deal.endTime && startTime.after(deal.endTime)) {

return "before.endTime"

}

})

This results in the following rendered jQuery validation code generation in my page:

startTime: {

date: true,

required: true,

validator: {

url: '/appContextRoot/JQueryRemoteValidator/validate',

type: 'post',

data: {

validatableClass: 'myapp.command.tester.testerDealCommand',

property: 'startTime'

}

}

}

Obviously, the custum constrains logic withing "validator:" does not work.

What is the best approach to get this custom validator working? 

1: Some form of Ajax call?

2: Use Custom Constraits plugin and add js code to grails-validation-methods.js?

3: Some other way?

I'm unsure of using option 2....is there some way to extend your plugin? 

I do not want to have to commit and maintain an seperate version of your plugin to our source code repository.

Thanks
