Question

您好，有点新，使用JayData和oData，请原谅我的无知。

这是我的对象结构：

$data.Entity.extend('PlannerModel.vMasterPlanner', {
    'Sequence_Number': { key:true,type:'Edm.Int32',nullable:false,required:true },
    'Scenario_Name': { type:'Edm.String',nullable:true,maxLength:250 },
    'Activity_ID': { type:'Edm.String',nullable:false,required:true,maxLength:250 },
    'Activity_Description': { type:'Edm.String',nullable:true,maxLength:500 },
    'Object_ID': { type:'Edm.String',nullable:true,maxLength:250 },
    'Object_Description': { type:'Edm.String',nullable:true,maxLength:400 },
    'Operation_Code': { type:'Edm.String',nullable:false,required:true,maxLength:250 },
    'Operation_Description': { type:'Edm.String',nullable:true,maxLength:50 },
    'Crew_ID': { type:'Edm.String',nullable:true,maxLength:250 },
    'Crew_Name': { type:'Edm.String',nullable:true,maxLength:50 },
    'Period': { type:'Edm.Int32',nullable:true },
    'vActivity': { type:'PlannerModel.vActivity',required:true,inverseProperty:'vMasterPlanners' }   });

 $data.Entity.extend('PlannerModel.vActivity', {
    'Activity_ID': { key:true,type:'Edm.String',nullable:false,computed:true },
    'Activity_Name': { type:'Edm.String',nullable:false,required:true },
    'vMasterPlanners': { type:'Array',elementType:'PlannerModel.vMasterPlanner',inverseProperty:'vActivity' }   });


$data.EntityContext.extend('PlannerServiceLibrary.PlannerEntities', {
    ProgressDetails: { type: $data.EntitySet, elementType: PlannerModel.ProgressDetails },
      ProgressHeaders: { type: $data.EntitySet, elementType: PlannerModel.ProgressHeader },
      vCrews: { type: $data.EntitySet, elementType: PlannerModel.vCrew },
      vPeriods: { type: $data.EntitySet, elementType: PlannerModel.vPeriod },
      vOperations: { type: $data.EntitySet, elementType: PlannerModel.vOperation },
      vActivities: { type: $data.EntitySet, elementType: PlannerModel.vActivity },
      vMasterPlanners: { type: $data.EntitySet, elementType: PlannerModel.vMasterPlanner }   });

只是一点点解释：表主计划程序是详细信息表，表活动是表头表我需要从活动表（标题）中选择所有活动，其中详细信息表中的工作人员ID例如= 2 我怎么能用oData和JayData

来做到这一点

目前正在使用

provider.vActivities.filter(function (ac) { 
return ac.vMasterPlanners.Crew_ID == "FM2_F/W" })
               .toArray(function (e) {
                   console.log(e);
               });

这是错误处理的未知表达式类型：EntitySetExpression 本地主机/移动网络/ htdocs中/资产/ jayData / jaydata.js 第89行

请帮助任何人!!

谢谢！

Answer 1

您需要'some'或'every'运算符，请参阅此http://jaydata.org/blog/using-some-and-every-with-jaydata-odata-provider

Answer 2

看起来我已将其添加到github http://github.com/jaydata/jaydata/issues/70

中的已知问题

使用JayData过滤标题详细信息表 - 内部连接SQL，oData
