Hi folks,
I have been asked by my current client to evaluate search functionality which could in
essence search for rules which are affected by a particular fact value.
For example, if we have a number of rules similar to the following format:
when
$req : TradeRequest(account = 10, buyCurrency = 'EUR', buyAmount > 5000000)
then
TradeValidationResponse response = new TradeValidationResponse();
response.setPermitted(false);
response.setMessage("Account 10 is not permitted to trade more than 5000000
EUR");
insert(response);
end
What the client is interested in is being able to search for all rules which have been
defined for account 10.
I was thinking to mess around with a rather quick and dirty solution to grab the package
source via the REST interface and pattern match rules in a very hard-coded way for this
specific use-case. However, that does look like a rather fragile way of achieving this.
So I was wondering whether anybody had looked at this sort of idea previously and might
have thoughts on a 'better' or more generic solution, which wouldn't be
massively complicated. I was thinking that it might be nice to extend the search mechanism
in Guvnor so that I could pick a fact from the model and do a search for all rules which
are based on the value of an attribute. However, every time I think about how that could
be achieved, it seems I come up with new ways in which it would become really difficult to
pull off.
Any thoughts?
Cheers,
Steve
