Hello,
I've only been working with Drools for a little over a month or so now and I've
begun integrating it into my application via Eclipse and creating DRL files. The nature
of this application is to take a data record from one file and create a new data record in
another file. This is done in a batch of any number of records, depending on the number
of records sent to us in the first file. To accomplish this I have two classes, one
representing each file, and I create and object for each of them, inserting them into the
knowledge session and then fire the rule.
ksession.insert(myObjectIn);
ksession.insert(myObjectOut);
ksession.fireAllRules();
The first object has around 1,000 fields and the second has 250, so my class structure is
quite broad.
In a DRL file I have created the following rule:
rule "Primary Diagnosis Code"
when
$ccl : anObjectIn(IncomingDiag1 != null)
$cdl : anObjectOut()
then
$cdl.PrimaryDiag = $ccl.IncomingDiag1;
end
This rule fires great and the PrimaryDiag field in myObjectOut is updated with what iss in
myObjectIn.IncomingDiag. I can then write the object back out the the database fine.
A requirement of my project is that I allow users (analysts) to create their own rules
that are above and beyond those I might create in a .drl file. To do so we are looking to
deploy Guvnor and let them use the Guided editor to create rules. I've already loaded
my fact models into Guvnor and have them available in the drop down conditions.
The questions that are hitting me now are:
1) On the LHS when I've chosen the fiels IncomingDiag the only options I have for
conditions are "equal to", "not equal to", "matches", and
"sounds like". I don't see an option for null or notnull. If I were to
choose "not equal to" I then have the options for Literal Values, New Formulas,
or Expression Editor (which has none by default). I haven't seen any examples where
someone is evaluating a field in Guvnor for being either "" or null. How would
one accomplish this? The literal value does not allow you to leave it blank as in
"" and if you type "" in it, the source shows
"""".
2) On the LHS, if I were to want to evaluate IncomingDiag1 == IncomingDiag2 I
don't see a method except if I were to choose New Formula and type in the field name
Incoming Diag2. Is there another way that they could be prompted for the field choises
again?
3) On the RHS, when I go to add a new then, I'm prompted to choose only to either
"insert fact anObjectIn" or to "logically insert fact anObjectIn" or
to manually enter DRL logic. Both of the inserts appear to create logic that would create
a new object with the data in it:
anObjectIn fact0 = new anObjectIn ();
fact0. IncomingDiag1 ( 11 );
insertLogical(fact0 );
But what I really want is something similar to my DRL from above. Am I missing
something? Or would this have to be a case where they would manually enter the DRL
statement?
Thank you!

Look at screen shot for questions 1 and 2
UI is a little screwy but you can check for null.
As for question 3, if you look at the source of your drl, you'll see if
you have a named reference to your object if not, you cannot use it on
the right hand side. If you look at my rule, I'm setting the contents
of *override *to *resultNumberToPick *which is what I think your trying
to accomplish.

Minh,
Thank you! The binding to a variable is the part I was missing in order to accomplish 2
& 3 and #1 was as simple as using the formula to say null.
Last night I worked through this and some matching Regex issues I had.
I do have two follow on questions if you don't mind:
1) Can the binding be done in another way where you don't have to set it up on
each rule?
2) How does one go about creating an "or" condition here in guvnor?
a. If ((string1 != null || string2 != "AB") && string1 !=
string2) then
b. If (string1 == "ABC" || string1 =="XYZ" |
string1=="QWERTY") then
These scenarios all seem so simple to me from a DRL hand coding, so I know they must be
able to be handled in guvnor and I'm just missing some subtle nuance.
I appreciate the help...

For question 1, if your asking can a object matched be automatically
set to a variable that you can later reference? No. You have to
provide the binding else how would you know how to reference it.
For question 2, the or part is tricky from the UI as you have to do the
and first then or embedded in the and. You accomplish that via
*Multiple field constraints*. So I guess you always want to start on
the outter condition and work your way in due to the quirkiness of the UI.

Minh,
Thank you again.
For #1, that will work for me.
For #2, actually, I figured this one out. Not completely intuitive, but I am starting to
get the feel for the UI and knowing what I do I think I could teach our users some of the
subtleties.
Have a great day!

Hello,
I’ve only been working with Drools for a little over a month or so now and
I’ve begun integrating it into my application via Eclipse and creating DRL
files. The nature of this application is to take a data record from one
file and create a new data record in another file. This is done in a batch
of any number of records, depending on the number of records sent to us in
the first file. To accomplish this I have two classes, one representing each
file, and I create and object for each of them, inserting them into the
knowledge session and then fire the rule.
ksession.insert(myObjectIn);
ksession.insert(myObjectOut);
ksession.fireAllRules();
The first object has around 1,000 fields and the second has 250, so my
class structure is quite broad.
In a DRL file I have created the following rule:
*rule* "Primary Diagnosis Code"
*when*
$ccl : anObjectIn(IncomingDiag1 != *null*)
$cdl : anObjectOut()
*then*
$cdl.PrimaryDiag = $ccl.IncomingDiag1;
*end*
This rule fires great and the PrimaryDiag field in myObjectOut is updated
with what iss in myObjectIn.IncomingDiag. I can then write the object
back out the the database fine.
A requirement of my project is that I allow users (analysts) to create
their own rules that are above and beyond those I might create in a .drl
file. To do so we are looking to deploy Guvnor and let them use the Guided
editor to create rules. I’ve already loaded my fact models into Guvnor and
have them available in the drop down conditions.
The questions that are hitting me now are:
1) On the LHS when I’ve chosen the fiels IncomingDiag the only
options I have for conditions are “equal to”, “not equal to”, “matches”, and
“sounds like”. I don’t see an option for null or notnull. If I were to
choose “not equal to” I then have the options for Literal Values, New
Formulas, or Expression Editor (which has none by default). I haven’t seen
any examples where someone is evaluating a field in Guvnor for being either
“” or null. How would one accomplish this? The literal value does not
allow you to leave it blank as in “” and if you type “” in it, the
source shows “”””.
2) On the LHS, if I were to want to evaluate IncomingDiag1 ==
IncomingDiag2 I don’t see a method except if I were to choose New Formula
and type in the field name Incoming Diag2. Is there another way that they
could be prompted for the field choises again?
If you create a bound variable, then you will see when you select the value
of the operateor a "bound variable" button. So that then you can select the
bound variable.
3) On the RHS, when I go to add a new then, I’m prompted to
choose
only to either “insert fact anObjectIn” or to “logically insert fact
anObjectIn” or to manually enter DRL logic. Both of the inserts appear to
create logic that would create a new object with the data in it:
anObjectIn fact0 = new anObjectIn ();
fact0. IncomingDiag1 ( 11 );
insertLogical(fact0 );
But what I really want is something similar to my DRL from above.
Am I missing something? Or would this have to be a case where they would
manually enter the DRL statement?
