Re: [rules-users] Smart Templates

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?

I do not see the need to use eval() at all. rule "DC_0" when $service: Service(name == "@{service}", value == "@{value}") $riskType: RiskType() then $riskType.setName($service.getType("@{value}")); $riskType.setAtt(0,"@{value}"); end I am assuming that RiskType is already inserted in WM, but you could just as well create a new object in the then-part of the rule. In stead of using the java-function to determine the name, you might actually just as well create an other rule that sets the name according to the value, thus putting the entire decision logic in rules. Hope this helps. Regards, Frank ChrisMu wrote: 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) .
