Hi, I'm trying to get a template (.drt) to generate 2 rules (.drl) from 2 datasets but by doing a little bit more work than direct substitution. Data (service,value): DC, AAA DC, XYZ Idea for the template - if value is of type1 then create Type object with 'Type1' as name. If value is of type2, use 'Type2' as name: rule "DC_(a){row.rowNumber}" when Service(name == "DC") then Type.setName(eval(Service.getType(@{value}))) Type.setAtt(0,@{value}) end template eval(Service.getType(@{arg0})) should take 'AAA' or 'XYZ' etc as arg and return a string Type1/Type2 etc. This would then generate 2 rules that look like: rule "DC_0" when Service(name == "DC", value == "AAA") then RiskType.setName("Type1") RiskType.setAtt(0,"AAA") rule "DC_1" when Service(name == "DC", value == "XYZ") then RiskType.setName("Type2") RiskType.setAtt(0,"XYZ") ...is this possible at all? I'm trying to avoid the eval step being done in the actual rule (.drl) . Thanks Chris

But then that would call the service.getType() method when the rule is run wouldn't it? I'm trying create explicit, simple rules to avoid doing extra work when running data through them. How would you use a rule to set the value within another rule?

If you want to avoid to execute the getType()-service at rule execution, then you would need to add an attribute name to your object, and call getType() before creating the rules. Alternatively, you can insert an intermediate value whose value will be set by another rule and then use this intermediate value in your DC rules. When Service(value = "AAA") Then String name = "Type1"; insert(name); Something like this... but make sure not to create a loop :-) Regards, Frank ChrisMu wrote: But then that would call the service.getType() method when the rule is run wouldn't it?

Ideally: Load the data from a DB and instantiate Java objects with that. Then generate the rule set using a template. The DB data would provide the list of permitted values per field. The rule results are generated based on the inputs. This avoids users having to enter one rule for every single currency and commodity type (using the example below) when there are only 2 underlying 'rules'. If another currency is then added to the data in the DB, the new rule will be automatically generated. ________________________________ From: FrankVhh [via Drools] [mailto:ml-node+3011148-1318721408-404175@n3.nabble.com] Sent: 01 June 2011 15:57 To: Mullard, Christopher Subject: RE: [rules-users] Smart Templates Hi, Basically, you have 2 options. 1) You call the function getType() from your .drl file.

Call JAva code if you don't want to put it all into DRL function, or import from Java in the first place. Both "import" and "function" can be used in spreadsheets. -W 2011/6/1 ChrisMu <[hidden email]> Agreed, but this was just an example - if the function required something more complicated - say a DB lookup, could it be done? ________________________________ From: Wolfgang Laun-2 [via Drools] [mailto:[hidden email] &lt;http://user/SendEmail.jtp?type=node&amp;node=3010490&amp;i=0&gt; ] Sent: 01 June 2011 12:40 To: Mullard, Christopher Subject: Re: [rules-users] Smart Templates If there are just 2 types (IRDELTA, COMLEASEDELTA) you can add a function that computes this from the 3-letter name. -W 2011/6/1 ChrisMu <[hidden email] &lt;http://user/SendEmail.jtp?type=node&amp;node=3010275&amp;i=0&gt; > Possibly. Let me try again with what I'm trying to achieve. Given this excerpt from a decision table: Basically I want to be able to specify a template that says 'If Arg0 is a currency, output RiskType IRDELTA (and currency), if Arg0 is a commodity (begins with 'X') then output RiskType COMLEASEDELTA (and commodity). When fed with data, this would generate the rules: when Arg0 = USD, output RiskType IRDELTA, USD when Arg0 = GBP, output RiskType IRDELTA, GBP etc when Arg0 = XAU, output RiskType COMLEASEDELTA, XAU etc In this way theRiskType name is inferred from the data when the rules are generated. It can be done by explicitly stating all possible combinations as in the decision table above but that gets tedious quickly. I wanted to have a more general template that could generate all the specific rules instances. Does that make more sense?

If you can generate N rules from N objects containing different literals for matching a fact or for updating a fact field, then you can achieve the same thing with a single rule and additional facts containing those literal values. rule "one 4 all" when   Service( $name: name, $value: value )   $sb: ServiceBean( name == $name, value == $value ) then   # RiskType ... is what?   ...$value..., ...$sb.getType()... end -W _______________________________________________ rules-users mailing list [hidden email] &lt;http://user/SendEmail.jtp?type=node&amp;node=3010097&amp;i=0&gt; https://lists.jboss.org/mailman/listinfo/rules-users ________________________________ If you reply to this email, your message will be added to the discussion below: http://drools.46999.n3.nabble.com/Smart-Templates-tp3006479p3010097.html To unsubscribe from Smart Templates, click here. ============================================================================== Please access the attached hyperlink for an important electronic communications disclaimer: http://www.credit-suisse.com/legal/en/disclaimer_email_ib.html ============================================================================== ________________________________ View this message in context: RE: [rules-users] Smart Templates &lt;http://drools.46999.n3.nabble.com/Smart-Templates-tp3006479p3010119.html&gt; Sent from the Drools: User forum mailing list archive &lt;http://drools.46999.n3.nabble.com/Drools-User-forum-f47000.html&gt; at Nabble.com. _______________________________________________ rules-users mailing list [hidden email] &lt;http://user/SendEmail.jtp?type=node&amp;node=3010275&amp;i=1&gt; https://lists.jboss.org/mailman/listinfo/rules-users _______________________________________________ rules-users mailing list [hidden email] &lt;http://user/SendEmail.jtp?type=node&amp;node=3010275&amp;i=2&gt; https://lists.jboss.org/mailman/listinfo/rules-users ________________________________ If you reply to this email, your message will be added to the discussion below: http://drools.46999.n3.nabble.com/Smart-Templates-tp3006479p3010275.html To unsubscribe from Smart Templates, click here. ============================================================================== Please access the attached hyperlink for an important electronic communications disclaimer: http://www.credit-suisse.com/legal/en/disclaimer_email_ib.html ============================================================================== ________________________________ View this message in context: RE: [rules-users] Smart Templates &lt;http://drools.46999.n3.nabble.com/Smart-Templates-tp3006479p3010490.html&gt; Sent from the Drools: User forum mailing list archive &lt;http://drools.46999.n3.nabble.com/Drools-User-forum-f47000.html&gt; at Nabble.com. _______________________________________________ rules-users mailing list [hidden email] https://lists.jboss.org/mailman/listinfo/rules-users _______________________________________________ rules-users mailing list [hidden email] https://lists.jboss.org/mailman/listinfo/rules-users ________________________________ If you reply to this email, your message will be added to the discussion below: http://drools.46999.n3.nabble.com/Smart-Templates-tp3006479p3010989.html To unsubscribe from Smart Templates, click here &lt;http://drools.46999.n3.nabble.com/template/NamlServlet.jtp?macro=unsubscribe_by_code&amp;node=3006479&amp;code=Y2hyaXN0b3BoZXIubXVsbGFyZEBjcmVkaXQtc3Vpc3NlLmNvbXwzMDA2NDc5fDE5NzczMDY1MzE=&gt; . =============================================================================== Please access the attached hyperlink for an important electronic communications disclaimer: http://www.credit-suisse.com/legal/en/disclaimer_email_ib.html =============================================================================== ________________________________ If you reply to this email, your message will be added to the discussion below: http://drools.46999.n3.nabble.com/Smart-Templates-tp3006479p3011148.html To unsubscribe from Smart Templates, click here &lt;http://drools.46999.n3.nabble.com/template/NamlServlet.jtp?macro=unsubscribe_by_code&amp;node=3006479&amp;code=Y2hyaXN0b3BoZXIubXVsbGFyZEBjcmVkaXQtc3Vpc3NlLmNvbXwzMDA2NDc5fDE5NzczMDY1MzE=&gt; . =============================================================================== Please access the attached hyperlink for an important electronic communications disclaimer: http://www.credit-suisse.com/legal/en/disclaimer_email_ib.html ===============================================================================
