subject:"RE\: \[rules\-users\] modify\(\)"

How to use boolean variables in the rule. I want to do this

rule
   when
  //condition
   then
  set a boolean to true
end


Then check at the last rule if all the boolean in the rules are true, which
tells me that all the rules have passed.

Thanks.

Re: [rules-users] modify and update is not working in the rule file

Although you can write

rule r
when ...
then
boolean b = true; ... x 
end

there is no way you can access these variables from anywhere else but
the place marked with x, i.e., inside the very same rule.

To see whether certain rules have fired in a certain interval, you'll
have to use some global data, either a DRL global or some other public
instance. At the beginning of the interval you'll have to clear the
variable, and at the end of the interval you'll have to iterate over
the accumulated collection.

For instance:

Java code:

SetString ruleNameSet = new HashSetString();
kSession.setGlobal( ruleNameSet, ruleNameSet );
//...
// Loop inserting a fact and firing all rules
for(...){
 ruleNameSet.clear();
 kSession.insert( anotherFact );
 kSession.fireAllRules();
 for( String ruleName: ruleNameSet ){
   //... ruleName has fired
 }
}

DRL code:

global Set ruleNameSet;

rule xyz
when...then...
ruleNameSet.add( drools.getRule().getName() );
end

Alternatively, to avoid the global and the addition to all right hand
sides, you can set up a listener and modify the SetString
ruleNameSet accordingly.

Re: [rules-users] modify and update is not working in the rule file

You must not use this:
   eval( boolBrandName  boolProviderState  boolDrugStrength )
since changes in global variables are not visible to the Drools rule engine.

But you don't need this eval(...) line, since you have
   rule Brand Name
   rule Provider State extends Brand Name
   rule Drug Strength extends Provider State
   rule Check extends Drug Strength
and therefore Check will not fire unless Drug Strength fires;
Drug Strength will not fire unless Provider State fires;
Provider State will not fire unless Brand Name fires.

Re: [rules-users] modify and update is not working in the rule file

ok, thank you so much for your help. It works. Thanks.

But one tough question for you.

How can I know what was the reason a rule condition failed. Lets say

rule
  when
 test( a == b )
  then
 //consequence
end

I want to know what caused the condition a==b to fail was the value of a
is b or anything else. and I need to log this to a log file.

Somebody told me that Verifier does the trick, but we need to add some
custom rules to get to the values. I tried to google lot on this. But I
never got anything which do what I want to do.

Please help me on this.

Thanks.

Re: [rules-users] modify and update is not working in the rule file

Hasn't this been answered only recently on this list?

1) For simple conditions, a rule negating the condition of your rule
will fire if the other one fails:

rule a != b
when
  test( a != b )
then
  //consequence
end

2) If you have rules extending each other, the first one not firing
contains the condition(s) that are not fulfilled.

3) An individual analysis of the attributes of a fact can be done,
collecting the conditions that are fulfilled. At the end of the
analysis, you either have the situation that all required attributes
are fulfilled (and you can execute the consequence) or not, and thus
you know what's missing.

That's what our Business doesn't want me to do to write negative rules. In
this way there will be 2 rules to be written for 1 business rule.

Re: [rules-users] modify and update is not working in the rule file

2012-08-17 Thread Stephen Masters

It's worth thinking about it differently. A rule does not fail. It just defines
the conditions under which it will activate.

If you wish to perform an action whether the condition is true or false, you
have 2 options:

A positive and a negative condition:
when
test(a == b)
then
...
when
test(a != b)
then
…

A condition which is always true:
when
test()
then
if (a.equals(b)) {
...
} else {
...
}

To be honest whether you write 1 or 2 rules should not be a 'business'
decision. Why does anybody think there should not be 2 rules?

It's probably worth considering what you're trying to achieve. Does logging of
a fact value really need to be part of a rule?

For instance, if you're actually just looking for an audit trail, you can have
a WorkingMemoryEventListener, which can listen for all of the fact insertions,
updates and retractions. It can log them all as they happen. Combined with an
AgendaEventListener, you can log what rules have activated and what the values
of facts were at the time. Use an asynchronous logger and this will have very
little impact on rules processing performance.

Alternatively if the business are writing rules, and only wish to write the
positive match, then maybe you can create a DSL which generates the both the
positive and negative rules behind the scenes.

A few ideas there for you to try...

Re: [rules-users] modify and update is not working in the rule file

To determine why some rule does not match, only proposals 2) and 3)
will work in the general case anyway.

If you're required to determine and log why rules do not fire, you'll
have to do what needs to be done. If you have, for example, 5
conditions, failure can be due to each, any combination and all of
them, and this information isn't available for free, and even your
Business should have enough savvy to understand that.

Either they drop the requirement, or they give you a free hand to fulfil it.

Re: [rules-users] modify and update is not working in the rule file

2012-08-17 Thread Davide Sottara

I agree with Stephen, if you need an action (e.g. logging) when a constraint
is violated, you are actually defining rules to handle the negative cases.
Drools verifier will not help you here, since knowing whether a fact
satisfied a constraint or not is a runtime problem and depends on the
combination of data and rules, whereas verifier looks at rules alone.

Could you please provide more details about your specific requirement? Do
you just need to know when a condition fails? Or do you need a full
analysis? I think we already discussed it: if you have a pattern with a
number of conditions, the engine will stop evaluating a fact as soon as the
first violation is encountered. Like in java, evaluation is terminated
eagerly. (In this case, the not CE would help).

Also consider this remark: when a constraint such as field == value is not
satisfied, the engine *silently* stops propagating the fact along that
branch of the RETE. So, there is no way to be notified of the failure of a
constraint.
The WorkingMemoryListener and the AgendaListener will report only events
with a coarser granularity, so they won't help you.

If you really really really ... really need it, you will have to tweak the
engine. I could show you a few possible ways to do that, but I'm a bit
reluctant...

Did you set the agenda-group AndroGel? If not, see some previous
mail in this thread.



 Also I want to know once the rules of a Rule file is fired and all is done

The next statement after fireAllRules() (see below!) is executed.

Re: [rules-users] modify and update is not working in the rule file

Yes I have that, but no luck. But again this should be dynamic so I am
guessing I should write if-else stmts to focus on?

ksession.getAgenda().getAgendaGroup( AndroGel ).setFocus(); 


* Logging is also not working in the rule file.
Logger logger = Logger.getRootLogger();

ksession.setGlobal(log, logger);

workingMemory = ksession;

workingMemory.insert(logger);
workingMemory.insert(drug);
workingMemory.insert(address);
workingMemory.insert(program);

( (StatefulKnowledgeSession) workingMemory).fireAllRules();


When it was working, I included a retract in my rule and flushed all the
facts from the memory and since then it is not working.

Thanks.

Re: [rules-users] modify and update is not working in the rule file

Ok it worked when I changed the rule file a little to add the negative rules.

But this should be dynamic so I am guessing I should write if-else stmts to
focus on for different drugs?

ksession.getAgenda().getAgendaGroup( AndroGel ).setFocus(); 


* Logging is also not working in the rule file.

Logger logger = Logger.getRootLogger();

ksession.setGlobal(log, logger);

Also I have new requirement saying that when a rule satisfies, they only few
rules to get fired based on the user input (like a grouped rules), so I
thought I will use activation-groups apart from agenda-groups. But how can I
focus on activating those activation-groups from Drools Rule File.

Thanks.

By the way, what are you trying to do in this piece of code?

CollectionObject objs = workingMemory.getObjects();
IteratorObject it = objs.iterator();

while (it.hasNext()) {
Object obj = it.next();
if (obj instanceof Program) {
FactHandle fact = workingMemory.getFactHandle(obj);
workingMemory.update(fact, obj);
}
}

One last thing. Just like Wolfgang said: if you don't activate the
agenda-group where the rule is defined its activations are never going to
be executed.

Re: [rules-users] modify and update is not working in the rule file

Something like
  kSession.getAgenda().getAgendaGroup( AndroGel ).setFocus();

With the way the rules are written an agenda-group doesn't appear to
be required at all, but who knows.

Re: [rules-users] modify and update is not working in the rule file

How can I fire one rule file if I have lot of rule files defined in my change
set. Right now I have written an if-else condition and checking if the input
is Androgel then fire Angrogel rule fire.

But how can I do that in real time.

Also I have a requirement which says it needs the reason why the rule
failed. So I have done this, I am setting all the actual and real values and
saving the data to database in my event listeners.

But I get this Cannot return a void result at line 6.


rule Brand Name
no-loop true
agenda-group AndroGel
when
$drug : Drug()
eval( progRuleValidationLog.setActualValue($drug.getBrandName()) )  
//line 6
eval( progRuleValidationLog.setRuleValue(AndroGel) )
Drug( brandName == AndroGel )
then
#drools.getWorkingMemory().setGlobal(boolBrandName, true);
log.info(Brand Name is AndroGel);
end


Thanks.

But a rule (as you have it) with
   Drug( brandName == AndroGel )
will take care of that automaticaliy. This can co-exist with lots of
similar rules for anything between Aspic to Zodiac.


 But how can I do that in real time.

 Also I have a requirement which says it needs the reason why the rule
 failed.

This is quite difficult if your rules are non-trivial except when there is a
restricted way facts are inserted and rules are fired. And even then it
requires a circumspect approach.

 So I have done this, I am setting all the actual and real values
 and
 saving the data to database in my event listeners.

Not clear what you gain by this.


 But I get this Cannot return a void result at line 6.

A method called in an eval must return a boolean, or has to be called
in a context that compares the result so that the comparison returns a
boolean. A void method can't be called at all.

Re: [rules-users] modify and update is not working in the rule file

The cancellation of an activation and the ensuing call to
activationCancelled() is NOT sufficient as an indication of the rule
not matching your fact data.

Scenario 1:
   - fact(s) inserted
   - activation created from rule R1
   - fireAllRules
   - activation of rule R1 fired

Scenario 2:
   - fact(s) inserted
   - activation created from rule R1
   - fireAllRules
   - fact(s) inserted/created/updated (due to another rule firing before R1)
   - activation from rule R1 cancelled

Scenario 3:
   - fact(s) inserted
   - fireAllRules
   - nothing happens

ok so what is the flow of  the failed condition of the rule. Also you did not

There is no flow for a rule not firing because one or more of its
conditions aren't met. Only recently I've suggested on this list a way
of determining why a rule does not fire. It requires a detailed,
individual investigation of the attributes contributing to the match.
Merely detecting that rules do not fire for a fact (or fact set) is
easier.

 Also you did
 not
 answer the first question of the function. It is not able to find my
