使用grails中的动态查找器搜索值

Question

我想通过两个领域,其使用动态查找器来搜索status和OpenOn(date).这个查询工作得很好:

 render(view:'list', model:[incidentInstanceList:Incident.findAllByStatusIlikeAndOpenOnGreaterThan("closed",new Date()-1,[sort:"id",order:"desc"])])

但是现在我试图通过三个字段搜索动态查找器,即UserId:status和OpenOn(date):

 render(view:'list', model:[incidentInstanceList:Incident.findAllByStatusIlikeuserIdIlikeAndOpenOnGreaterThan("closed","${session.user.userId}",new Date()-1,[sort:"id",order:"desc"])])

此查询无法正常运行并显示错误:

No signature of method: app.Incident.findAllByStatusIlikeuserIdIlikeAndOpenOnGreaterThan() is applicable for argument types: (java.lang.String, org.codehaus.groovy.runtime.GStringImpl, java.util.Date, java.util.LinkedHashMap) values: [closed, tt10004, Wed Aug 24 15:12:21 IST 2011, [sort:id, order:desc]] Possible solutions: findAllByStatusIlikeuserIdIlikeAndCreatedOnGreaterThan(java.util.List) 

请指导我解决这个问题.

Answer 1

def incidentInstanceList = {

    def criteria = Incident.createCriteria()

    def results = criteria {
        and {
            user {
                like('userId', "${session.user.userId}").toString()
            }
            like('status',  "Closed" ) 
            gt('closedOn',new Date()-1)
            sort("id", "desc")
        }  

    } 

    render(view:'list', model:[ incidentInstanceList: results, incidentInstanceTotal: Incident.count()])        
}
