Hello, The dataModel is as following: class AgeRange() { Integer code; int minAge; int maxAge; } Campaign() { List<Integer> listOfAgeRangeCodes; } Subscriber() { int age; } AgeRange()'s and Campaign()'s are pre-populated into the WM. Subscriber() is asserted right before fireAllRules is called. I need a rule that would allow me to check if Subscriber() is within one of the defined on the Campaign() AgeRange()'s. What would be the most efficient way to enforce this constraint? The other possibility I see is to store the list of AgeRange()'s in each Campaign() and then use eval() to iterate over the list... Advice and ideas are appreciated. Thank you, Maxim. -- Cheers, Maxim Veksler "Free as in Freedom" - Do u GNU ? _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Thank you very much for the fast and accurate reply David, Is it also possible to use the opposite positioning?, something like: Subscriber($age : age) Campaign($campaignAgeRangs : listOfAgeRangeCodes) AgeRange(minAge <= $age, max >= $age, $campaignAgeRangs contains code) Please don't try the above as this tries to create a field extractor for $campaignAgeRangs on the AgeRange object which fails for obvious reasons.. I would like to to filter first by Subscriber, then by Campaign and last by age range. This is obviously a simplification of the actual filtering rules.

Hello Again David / List, I should have probably mentioned that I'm working with Drools 3, I'm not sure how or "if" this can be implemented in Drools 3 syntax. I've tried to search Drools 3 documentation and googled for this. Currently I'm using contains with first finds the age groups then follows to find the matching Campaing but as I already know what campaign I'm checking and my intention is to check if this campaign can accept this age group I would like to reverese the search order... Ideas are very welcome. Happy new year everyone ! On Sun, Dec 21, 2008 at 10:20 PM, David Sinclair < dsinclair(a)chariotsolutions.com&gt; wrote: > u almost had it.

Obviously I can. Thank you very much David for you motivation to help. Here is the relevant set of rules as it's looks in My Drools3 .drl file: (Please see comments after the drl). """ rule "4" // Campaign Age Range Groups no-loop when $f : FilteringStateConnector(connectorIndex == 4, $campaignId : campaignId, $subscriberId : subscriberId) eval ($f.getCampaign().getAgeRangeGroups().size() > 0) $subscriber : DynaSubscriber(id == $subscriberId, age != null, $subscriberAge : age ) eval(com.ml.common.utils.BooleanLogging.trace(log, "common.drl R:4 **** DynaSubscriber() " + $subscriber)) // Locate age group(s) subscriber is categorized within. $ageGroup : AgeGroup(lowValue <= $subscriberAge, highValue >= $subscriberAge, $ageGroupCode : code ) eval(com.ml.common.utils.BooleanLogging.trace(log, "common.drl R:4 ******** AgeGroup() " + $ageGroup)) // Check if campaign contains this AgeRange Group. DynaCampaign( code == $campaignId, ageRangeGroups contains $ageGroupCode ) eval(com.ml.common.utils.BooleanLogging.trace(log, "common.drl R:4 AgeGroup verified for Subscriber: " + $subscriberId + " at Campaign: " + $campaignId)) then $f.setPassedRuleRecord("4"); $f.setConnectorIndex(500); modify($f); end rule "[XOR NO COUNTING RULE] 4" // Campaign AgeGroup when $f : FilteringStateConnector(connectorIndex == 4, $campaignId : campaignId, $subscriberId : subscriberId) eval ($f.getCampaign().getAgeRangeGroups().size() == 0) eval(com.ml.common.utils.BooleanLogging.trace(log, "common.drl R:4 AgeGroup NOT CHECKED for Subscriber: " + $subscriberId + " at Campaign: " + $campaignId)) then $f.setPassedRuleRecord("4"); $f.setConnectorIndex(500); modify($f); end """ What I'm trying to do with these 2 rules is check if I need to verify age ranges for subscriber, if so [rule "4"] is firing, I already know the campaign I'm checking so I would like to first locate it, then fetch it's ageRangeGroups and only then check of each of the groups if it matches by it's ranges to the subscriber age range - 1 match is enough to stop the search. What I'm doing now is first location all the AgeGroup objects that match the subscriber and then check (for each) of the groups is it matches the campaign collection. Please again note that I'm using Drools 3, we're considering here Drools4 but for now It's hard core 3. Thank you, Maxim.
