我在windowReceiver组件的onReceiver事件中已经取到了这个task_id任务id, event.data.task_id

这个过滤是应该写到这个modelLoad这个事件里面去吧,那我在这个事件里面我应该怎么获取到这个task_id啊?

jishuang

直接在onReceiver事件中过滤数据就可以，不是必须在onload中去过滤数据

tlkj

请问下这是什么情况啊?var task_id = event.data.task_id;
                data.setFilter("filter1", "takePhoto.task_id ='" + task_id + "'");

是因为没有匹配的值吗?

createTakePhotoAction
报错的是新增的时候出错的，不是过滤数据刷新出错的

tlkj

这是之前在modelLoad事件中写的能实现这个只显示当前登陆者的.
Model.prototype.modelLoad = function(event) {
                data = this.comp("attData");
                alert(event.data.task_id);
                var personName = this.getContext().getCurrentPersonName();
                data.setFilter("filter1", "takePhoto.user_id ='" + personName + "'");
                data.refreshData();
                if (data.getCount() == 0) {
                        data.newData();
                }
                ;
        }

那我现在在这个onReceiver事件中写就报23的错,而且现在attachment这个控件里面显示的照片还是当前登陆者上传的.
不能实现当前任务的照片展示
Model.prototype.preReceiverReceive = function(event){
               
                data = this.comp("attData");
                alert(event.data.task_id);

                var task_id = event.data.task_id;
                data.setFilter("filter1", "takePhoto.task_id ='" + task_id + "'");
                data.refreshData();
                if (data.getCount() == 0) {
                        data.newData();
                }
                ;
        };

报错是因为主键task_id没有设置默认值，平台的概念中设置主键关系的关系必须设置默认值

tlkj

takePhoto.task_id ='" + task_id + "'"

如果takePhoto表的数据里面没有这个event.data.task_id所对应的值,那么attachment控件展示值的时候是不是应该什么不显示???可是现在展示的还是当前登陆者所拍的照片呢...

jishuang

没有值你都执行了newData了啊，看看是不是自己给这个关系设置了有默认值
newData就是新增一条数据了

tlkj

现在改了一下,这个task_id不是主键了,主键改成fid了,这个task_id是从列表中取出来,通过this.comp('windowsdialog').open({data:{task_id}})传过去的,
当我选中照片上传的时候,怎么在上传这个按键onclick事件中拿到这个task_id然后报存呢?

如果要获取data中的数据就有data的getValue方法获取
