Grails-如何查询列表

Question

我有一个域类这样

Class Rules{ 
    List <Department> departments = new ArrayList<Department>() 
    // blah blah 
    static hasMany = [departments:Department] 
} 

    Class Department { 
    String name 
    } 


def listOfRules= // find the rules based on department selected 

我试图让所有包含选定的部门..所以我如何可以查询..

规则这是使用hibernate的grails应用程序。

Answer 1

List departmentIds = [] 
// Code to populate departmentIds goes here 

def rulesWithTestingDepartment = Rules.withCriteria { 
    departments { 
    'in'('id', departmentIds) 
    } 
}
