模型驱动应用使用插件实现跳转业务流程阶段跳转功能

在实际操作中总会遇到使用业务流程的需求,那么如何使用plugin实现跳转阶段的功能呢

需求背景是主表上有业务流程,子表上有一个选项集字段,选项集字段包含所有的业务流程阶段,在更新子表的选项集时主表的业务流程阶段也需要同步跳转。
由于创建和更新查询不同,所以可以写两个plugin 也可以写在一个中使用message去控制

//创建时执行
if (Context.MessageName=="Create")
   {
       //查询刚刚触发创建的业务流程(业务流程实体)
       string strXml = "";
              strXml += "";
              strXml += "";
              strXml += "";
              strXml += "";
              strXml += "";
              strXml += "";
              strXml += "";
              strXml += "";
              strXml += "";
              strXml += "";
              strXml += "";
              strXml += "";
              strXml += "";
              strXml += "";
              strXml += "";
              strXml += "";
              EntityCollection start = Service.RetrieveMultiple(new FetchExpression(strXml));
              if (start.Entities.Count > 0)
              {
                   Entity Entitytag = Service.Retrieve("new_salesopportunity", start.Entities[0].GetAttributeValue<EntityReference>("bpf_new_salesopportunityid").Id, new ColumnSet("new_phase", "new_businesstype"));
                   //如果包含阶段
                   if (Entitytag.Contains("new_phase"))
                   {
                            //查询需要跳转的阶段(流程阶段值实体)
                            string StageFetch = "";
                            StageFetch += "";
                            StageFetch += "";
                            StageFetch += "";
                            StageFetch += "";
                            StageFetch += "";
                            StageFetch += "";
                            //这里是阶段id 也可以再查一次,这里不大严谨就直接放入了id
                            StageFetch += "";
                            //根据选项集的name搜索我们要跳转的阶段
                            StageFetch += "";
                            StageFetch += "";
                            StageFetch += "";
                            StageFetch += "";
                            EntityCollection steges = Service.RetrieveMultiple(new FetchExpression(StageFetch));
                            if (steges.Entities.Count > 0)
                            {
                                //修改流程阶段
                                Entity getProcess = new Entity("new_start");
                                getProcess.Id = start.Entities[0].Id;
                                getProcess["activestageid"] = new EntityReference("processstage", steges.Entities[0].Id);
                                //更新流程阶段
                                Service.Update(getProcess);
                            }
                        }
                    }
                }
                

下面是update时执行,我把它拆开了

else if (Context.MessageName == "Update")
        {
            Entity Entitytag = Service.Retrieve("new_salesopportunity", target.Id, new ColumnSet("new_phase", "new_businesstype"));
            if (target.Contains("new_phase"))
               {
                  //查询需要跳转的阶段(update时候直接查询流程阶段实体即可)
                 string StageFetch = "";
                        StageFetch += "";
                        StageFetch += "";
                        StageFetch += "";
                        StageFetch += "";
                        StageFetch += "";
                        StageFetch += "";
                        StageFetch += "";
                        StageFetch += "";
                        StageFetch += "";
                        StageFetch += "";
                        StageFetch += "";
                        EntityCollection steges = Service.RetrieveMultiple(new FetchExpression(StageFetch));
                        if (steges.Entities.Count > 0)
                        {
                            //查询触发创建的业务流程
                            string strXml = "";
                            strXml += "";
                            strXml += "";
                            strXml += "";
                            strXml += "";
                            strXml += "";
                            strXml += "";
                            strXml += "";
                            strXml += "";
                            strXml += "";
                            strXml += "";
                            strXml += "";
                            strXml += "";
                            strXml += "";
                            strXml += "";
                            strXml += "";
                            strXml += "";
                            EntityCollection start = Service.RetrieveMultiple(new FetchExpression(strXml));
                            if (start.Entities.Count>0)
                            {
                                //修改流程阶段
                                Entity getProcess = new Entity("new_start");
                                getProcess.Id = start.Entities[0].Id;
                                getProcess["activestageid"] = new EntityReference("processstage", steges.Entities[0].Id);
                                //更新流程阶段
                                Service.Update(getProcess);
                            }
                        }
                    }
                }

然后把这个plugin注册在子表上的create 和 update 即可,这里看具体的业务需求实现
当然如果觉得plugin麻烦也可以同理写一个前端的js来实现。
