Question

我是grails的新手，并试图根据Embedded class的日期字段获取Domain列表。

以下工作正常

def res = User.findAll { lt 'createdDateTime', new Date }

def res = User.findAll { eq 'account.name', 'JOHN' }

但是，

def res = User.findAll { lt 'account.createdDateTime', new Date }

以上总是返回空列表。

＆＃39;帐户＆＃39; class嵌入到User类

中

User.groovy

class User {
   String name
   Integer age
   Date ctratedDateTime // test
   Account account
   static embedded = [
      'account'
   ]
}

Account.groovy

class Account {
    String userName
    String password
    Date createdDateTime
}


def res = User.findAll { 
  account{ 
    lt 'createdDateTime', new Date 
  }
}

上面收到以下错误

org.codehaus.groovy.grails.web.servlet.mvc.exceptions.ControllerExecutionException: Executing action [list] of controller [com.test.UserController]  caused exception: Runtime error executing action

我是以正确的方式做的吗？请建议我解决的方法。

感谢。

你应该使用嵌套闭包：

def res = User.withCriteria{ 
  account{ 
    lt 'createdDateTime', new Date 
  }
}

基于嵌入式日期字段的Grais列表不起作用
