本文介绍: 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。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。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。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。模型驱动应用使用插件实现跳转业务流程阶段跳转功能。

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 = "<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false'>";
strXml += "<entity name='new_start'>";
strXml += "<attribute name='businessprocessflowinstanceid' />";
strXml += "<attribute name='bpf_name' />";
strXml += "<attribute name='createdon' />";
strXml += "<attribute name='bpf_new_salesopportunityid' />";
strXml += "<attribute name='activestageid' />";
strXml += "<attribute name='statecode' />";
strXml += "<attribute name='statuscode' />";
strXml += "<attribute name='createdby' />";
strXml += "<attribute name='processid' />";
strXml += "<order attribute='bpf_name' descending='false' />";
strXml += "<filter type='and'>";
strXml += "<condition attribute='businessprocessflowinstanceid' operator='eq' value='" + target.Id + "' />";
strXml += "</filter>";
strXml += "</entity>";
strXml += "</fetch>";
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 = "<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false'>";
StageFetch += "<entity name='processstage'>";
StageFetch += "<attribute name='processstageid' />";
StageFetch += "<attribute name='processid' />";
StageFetch += "<attribute name='stagename' />";
StageFetch += "<order attribute='stagename' descending='false' />";
StageFetch += "<filter type='and'>";
//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 += "<condition attribute='processid' operator='eq' value='{5674a97c-e2d7-4ae6-9dfa-15a8ad0fa340}' />";
//根据选项集的name搜索我们要跳转的阶段
StageFetch += "<condition attribute='stagename' operator='eq' value='" + Entitytag.GetAttributeValue<EntityReference>("new_phase").Name + "' />";
StageFetch += "</filter>";
StageFetch += "</entity>";
StageFetch += "</fetch>";
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 = "<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false'>";
StageFetch += "<entity name='processstage'>";
StageFetch += "<attribute name='processstageid' />";
StageFetch += "<attribute name='processid' />";
StageFetch += "<attribute name='stagename' />";
StageFetch += "<order attribute='stagename' descending='false' />";
StageFetch += "<filter type='and'>";
StageFetch += "<condition attribute='processid' operator='eq' value='{5674a97c-e2d7-4ae6-9dfa-15a8ad0fa340}' />";
StageFetch += "<condition attribute='stagename' operator='eq' value='" + Entitytag.GetAttributeValue<EntityReference>("new_phase").Name + "' />";
StageFetch += "</filter>";
StageFetch += "</entity>";
StageFetch += "</fetch>";
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 = "<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false'>";
strXml += "<entity name='new_start'>";
strXml += "<attribute name='businessprocessflowinstanceid' />";
strXml += "<attribute name='bpf_name' />";
strXml += "<attribute name='createdon' />";
strXml += "<attribute name='bpf_new_salesopportunityid' />";
strXml += "<attribute name='activestageid' />";
strXml += "<attribute name='statecode' />";
strXml += "<attribute name='statuscode' />";
strXml += "<attribute name='createdby' />";
strXml += "<attribute name='processid' />";
strXml += "<order attribute='bpf_name' descending='false' />";
strXml += "<filter type='and'>";
strXml += "<condition attribute='bpf_new_salesopportunityid' operator='eq' value='" + target.Id + "' />";
strXml += "</filter>";
strXml += "</entity>";
strXml += "</fetch>";
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。
