返回自定义验证器错误Grails [英] Return Custom Validator Error Grails

问题描述

我只获得默认验证器消息。我做错了什么？

I'm only getting the default validator message. What am I doing wrong?

class Questao {


static hasMany = [alternativas:Alternativa]

static constraints = {

    alternativas (validator: {val, obj ->
       if(val.size() < 2)
            return ['validator.message'] //custom message
        })
}
}

/ i18n

questao.alternativas.validator.message = "must be greater than two"

default.invalid.validator.message= Property [{0}] of class [{1}] with value [{2}] does not pass custom validation

感谢

推荐答案

返回包含您的消息代码的列表 - 您只需返回代码：

You're returning a list containing your message code - you need to return just the code:

alternativas validator: { val, obj ->
   if (val.size() < 2) {
      return 'validator.message' //custom message
   }
}
