如何使用grails中的ajax-jquery创建表

Question

如何使用grails中的 ajax-jquery 创建表格。 请帮帮我

我只想在grails中使用 ajax-jquery 创建表格。

这是我的代码

Project.groovy

package com.moog

class Project {

String project
Workpackage workpackage
String activity
static hasMany=[workpackage:Workpackage]


static constraints = {
    project  blank:false,unique:true
     workpackage  blank:false,unique:true
     workpackage nullable:true
     activity  blank:false,unique:true
     activity nullable:true
     project nullable:true
        }
static mapping={


}
}

workpackage.groovy

package com.moog

class Workpackage {

static belongsTo=[project:Project]

String workpackage

static constraints = {

    project nullable:true

    workpackage blank:false,unique:true

    workpackage nullable:true

}
}
