Question

我是Grails的新手，我的情况是我要将智利元素限制为5。

所以使用大小约束。

static constraints = {
  favoriteEplCircuitIds size 1..5
} 
 And static hasMany = [favoriteEplCircuitIds: String]

现在在我的测试用例中，当我使用父级时，我期待'size.toobig'。。错误['child']

但是我得到了一个太长的例外......如何压制它？

@Burt：根据您的建议，我使用了

 assert 'size.toobig' == obj.errors.getFieldError('favoriteEplCircuitIds')

...但仍然收到以下长错误消息。

Answer 1

语法错误。它应该是

static constraints = {
   child size: 1..5
}

假设你有

static hasMany = [child: SomeOtherDomainClass]

尽管多数化集合名称会更自然，例如“孩子”。但那是化妆品，与你所看到的问题毫无关系。

修改

您可以使用
访问错误
def error = parent.errors.getFieldError('children')

但是toString（）的可读性不高。要获得您在GSP中看到的错误，依赖注入“messageSource”bean，例如

def messageSource

然后您可以使用
获取错误消息
String message = messageSource.getMessage(error, Locale.default)

它应该是这样的：

Property [children] of class [class Parent] with value [[c1, c2, c3, c4, c5, c6]] does not fall within the valid size range from [1] to [5]

Grails域类中的Size约束问题？
