我正在编写一个引发事件的应用程序,类似于Phil Windley personal data manager application的工作方式。但是,如果我尝试使用任何事件域而不是explicit
,则事件不会传播。以下规则适用于explicit
作为域,但不适用于driverreg
。
rule driver_info_submit {
select when web pageview ".*"
pre {
driver_name = "Joe Driver";
driver_phone = "111-555-1212";
msg = <<
Current driver info: #{ent:driver_name}, #{ent:driver_phone}
>>;
}
notify("Started", msg);
fired {
raise explicit event new_driver_data with driver_name=driver_name and driver_phone=driver_phone;
}
}
// Save driver name
rule save_driver_name {
select when explicit new_driver_data
pre {
driver_name = event:param("driver_name") || ent:driver_name;
driver_phone = event:param("driver_phone") || ent:driver_phone;
}
noop();
always {
set ent:driver_name driver_name;
set ent:driver_phone driver_phone;
raise explicit event driver_data_updated;
}
}
rule driver_info_updated {
select when explicit driver_data_updated
{
notify("Driver name", ent:driver_name);
notify("Driver phone", ent:driver_phone);
}
}
应用程序是否已部署似乎不成问题,因为我已经尝试过两种方式。我错过了什么?
答案 0 :(得分:2)
在raise语句中只允许某些域作为域:
将来可能会放松。
