[rules-users] Rule Templates - Conditionally Generate Rule based on Values in Data
All,
I saw this question was asked a couple of months ago with no reply, but thought
I would try again.
In using a Rule Template, I'm trying to determine a way to dynamically generate
rules based on a value in the data.
There is a data set, that has various pieces data, depending on a column value,
the rule that is generated is relatively different. Different enough that I
wouldn't want the generated a rule for each row of data, because many of the
rules generated would never fire.
In the drools expert docs, it lists under 6.1.7 Rule Templates the ability to
conditionally generate rules based on the values in the data, but I can't
seem to find the syntax for how to do that.
Does anyone know the answer to this?
I would picture it looking something like this
if (@{RevenueCode} == NR)
rule RevenueMapperRule_1
when
claim1 : ClaimFact (ProgramType in (FC, FCP, FALSE, FALSE),
ProcedureCode == NR,
(serviceBegin = 01-Oct-2003
serviceBegin = 31-Dec-2030),
modifier1 in (U),
typeofBill == 3);
then
claim1.setResultSPCCode(507.11);
list.add(claim1);
end
end if
Essentially, the only time this rule would be generated is if RevenueCode in
the Rules Spreadsheet had a value of NR.
If this is not possible, how should I be thinking about this problem? Feels
weird to generate a bunch of rules that will never fire, simply because there
is no way to conditionally generate a rule. Maybe the answer is to create
separate rule files and template definitions? That also feels like an over
complication.
Thoughts?
Thanks in advance!

Re: [rules-users] Rule Templates - Conditionally Generate Rule based on Values in Data
A *rule template *is a text (file) intended to be expanded repeatedly using
different sets of template parameters, similar to a macro processor. Each
expansion will generate - more or less - the same rule, unless you put the
flexibility into the parameter, which just passes the buck to the code
driving the expansion.
Let's say that you want to be alerted if one of your lucky numbers becomes
a fact. You can write a template, create a collection of your lucky numbers
and run the expander to create one rule for each of your lucky numbers.
This is explained in section Expanding a Template.
Most of the time, sets of almost identical rules can be avoided if facts
containing parameter sets are inserted and rules are written to match the
values from a ParameterSet fact rather than literals, as would be done by
generated rules. Consider
when
Integer( valueOf == 7 )
when
Integer( valueOf == 13 )
as opposed to
when
Parameter( $n: number )
Integer( valueOf == $n )
with appropriate Parameter facts (7, 13).

[rules-users] Rule Templates and Array Handling
Hi All,
I'm trying to determine if it's possible to process arrays of data using Rule
Templates. An example of what I'm trying to accomplish.
Spreadsheet of rules, with one of the columns being valid colors. Valid colors
contains comma separated data and is variable length.
For example
It might contain: Blue, Green, Red or Blue, or Red, Green, Purple, Silver
Any number of entries.
I then need to process incoming fact values against this list of colors, using
either CONTAINS or IN.
For example:
template header
desc
valid_colors[]
package org.drools.examples.templates
global com.sample.Product product;
template ColorTestTemplate
rule ColorRule_@{row.rowNumber}
when
product1 : Product (Color in @{valid_colors});
then
product1.setDesc(@{desc});
end
end template
I know the following doesn't work: product1 : Product (Color in
@{valid_colors});
However, I wanted to depict what I'm trying to accomplish.
The challenge is with valid_colors being a variable length array, I can't refer
to the individual values using constants i.e. valid_colors0, valid_colors1,
valid_colors3, etc to build my array list.
ie Color in (@{valid_colors0}, @{valid_colors1}, @{valid_colors2})
Is there a way to iterate through a variable length array in a template?
Any thoughts on how I could build an array list i.e. (Blue, Green, Red)
when the column contains a variable length array?
Thanks in advance,
Jason___

Re: [rules-users] Rule Templates and Array Handling
In the spreadsheet (with class Country) you would have a column such as:
CONDITION
Country
name in ( $param )
Test whether name is one from a given set
Austria, Germany, Switzerland
France, Canada, Belgium
This is the generated rule:
rule InTest_18
when
$country: Country(name in ( Austria,Germany,Switzerland ))
then
System.out.println( German is spoken );
end
You should be able to retrofit the template from this. (Why do you
need a template when you have a spreadsheet?)

Re: [rules-users] Rule Templates and Array Handling
Thanks for the reply Wolfgang.
I chose to use the template because I liked the idea of separating the rule
definition from the rule data. Just seemed intuitive to me. Overall, I'm new
to Drools, so not sure if that is the best choice or not.
I think your approach works if my spreadsheet has all the items separated with
commas and double quotes. Because then it's just referring to the field as a
simple string field, not an array of values.
When the field is in the spreadsheet as: Austria, Germany, Switzerland it needs
to be handled as an array, otherwise it will build the generated rule as:
Country(name in (Austria, Germany, Switzerland)) and fail compile because it's
missing the quotes. If you use @{country}) it will put (Austria, Germany,
Switzerland), when you really need (Austria, Germany, Switzerland)
Maybe I'll just embed the double quotes in the spreadsheet and call it a day,
instead of fighting the field as an array of values.
If you have any other thoughts, let me know!
Thanks,
Jason.

Re: [rules-users] Rule Templates and Array Handling
If you are expanding the template with data taken from anywhere
you have the option of processing that data before you pass it
to the expander. Section 2.5.2., Expanding a Template, explains
how to do this. This is the option you have for implementing
specific processing.
The problem with data in a spreadsheet is that it doesn't have
much of a data type along with it, so an entry such as x,y,z
could be any of these: one string value, a list of numbers, a list
of three string values, with quotes omitted, a list of enums, and so on.

Re: [rules-users] Rule Templates and Array Handling
Thanks Wolfgang.
I think I see what you're saying. If I need to do any complex prep, simply
process it first, then build a collection of POJO objects for expansion by the
drools template.
I also understand what you're saying about spreadsheets. Most of this is just
proof of concept I'm doing…I think you're right in maintaining the rule data
somewhere else…i.e. database.
Thanks again for your help.

Re: [rules-users] Rule Templates
The information that would help me is (using Eclipse or JBDS) can one edit, It depends if you mean edit the templates or edit the data that you use to populate it. You can create a rule template in any text editor you like and, AFAIK, it can have any extension you prefer. Convert it to an inputstream and use it in the code as is documented. Regarding the data source, you have multiple options to collect the data. Editing this data depends a bit on the type you are using. I typically convert xml objects to java objects and use (and, sometimes, abuse) them to fill the template and generate rules. compile to drl Compile to drl is done using the code as documented. String drl = converter.compile( objs, templateStream ); You can do with the String whatever you like. use it to feed a knowledgebuilder directly, or write it to a file. and test the rule templates Again. This depends on what you mean. If test the rule templates means: check whether it generates a correct drl, than there are 2 things you can do. 1) Manually check that the rules are as you expect them to be. 2) Verify that the drl compiles in a knowledgebuilder. If test means, check whether my generated rules can construct a correct decision, then you wikk have to set up a service/a method/ a unit test in which you use the rules to create a knowledge base and which takes input data to generate a certain output. If you want, you can use guvnor to create test scenarios or implement a testing tool by your own. Regards, Frank mclovis wrote Frank, Thank you for your quick reply. I had previously read your suggested documentation and understand the basics of rule templates.

Hi all, In the Expert Guide and on some places on the internet, I read about Rule Templates. I think this is a very interesting feature. However, the expert manual states to use it with caution as it is still an experimental feature. Also, there isn't that much information on the web either. Is it already encouraged to use it in production, or is it still very much in a development phase and should it only be used for educational purposes?

Re: [rules-users] Rule Templates
Hi W.,
Thanks for the fast reply.
Meanwhile, I have been trying to play with the templates. Unfortunately, I
run into a nullpointerexception in the problems view of Eclipse. At first, I
hoped it was the same error as in
http://lists.jboss.org/pipermail/rules-users/2010-November/017229.html but
that does not seem to be the case.
Underneath, you can find my drl file. This is the only artifact that I am
having right now. There is no Java code yet, apart from the Price object.
This shouldn't be necessary to fix the problem either.
I tried to comment out some pieces of code to narrow down on the problem.
The nullpointerexception persists even if you comment everything from
package to the bottom of the file. This should indicate the problem has to
be in the template header, but I do not have a clue.
Could anyone help with this?
Thanks in advance.

Re: [rules-users] Rule Templates
Hi,
After trying the example from the documentation, eclipse returned the same
error. So, I got the same idea and just worked further ignoring eclipse.
I saw what I saw and that was that it works fine now, even with the error
still displayed in the problems view.
Thanks for the help ;-)

It works out of the box. So in this example:
12 rule Cheese fa...@{row.rownumber}
13 when
14Person(age == @{age})
15Cheese(type == @{type})
16 then
17list.add(@{log});
18 end
If you provide age=null, line 14 is not included in the rule
automatically.

[rules-users] Rule Templates with empty cells
Hi!
If I write rules in a decision table I can leave cells empty if I don't need
to use all of the conditions in a row.
How can I do this with the ExternalSpreadsheetCompiler?
I would need something like:
rule ru...@{row.rownumber}
when
$s : MyType1()
@ifDefined{field1} $e : MyType2(val1 == @{field1}) from $s.SUB;
@ifDefined{field2} $e : MyType2(val2 == @{field2}) from $s.SUB;
then
retract($s);
end
Thanks
Juergen

Re: [rules-users] Rule Templates - Docs Examples?
Looking at the 5.1 snapshots, these sections have not been updated since the 5.0 release. I'm looking at a 5.1 snapshot I downloaded on 11/2/09. The relevent sections, specifically 5.1.7 and 5.2, seem to have errors and/or omissions and those sections should have the information I'm looking for. Unfortunately I don't know what the correct info should be, so I can't submit an edit myself. As an example, from the last part of 5.1.7: snip The code to run this is simple: KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder(); DecisionTableConfiguration dtconf = KnowledgeBuilderFactory.newDecisionTableConfiguration(); dtconf.setInputType( DecisionTableInputType.XLS ); dtconf.setWorksheetName( Tables_2 ); kbuilder.add( ResourceFactory.newInputStreamResource( getSpreadsheetStream() ), ResourceType.DTABLE, dtconf ); CollectionKnowlegePackage kpkg = kbuilder.getKnowlegePackages(); We create an ExternalSpreadsheetCompiler object and use it to merge the spreadsheet with the rules. The two integer parameters indicate the column and row where the data actually starts - in our case column 2, row 2 (i.e. B2) /snip The docs discuss creating an ExternalSpreadsheetCompiler in the example to merge the spreadsheet with the rules template, but the example is for a standard DecisionTable, without a custom template. In section 5.2, it goes over templates, but does not discussion optional values or array values. I have reviewed the Drools-Example files. There is an example in there of using array values, but not an example using optional values, which is what I particularly need.

We want to but so far have had little end user feedback on templates, so they are still classed as experimental. If it gets more community support and the community helps mature the api and featureset we will look to support this fully. It's just there are lots of different ways the templates could work, not just from excel, but any tabular data source like a DB, so want to make sure we get it right and it's just been a lower priority than getting drools 5.0 out the door.

But you can use the copy function in the rule editor. Create a rule that is used as a base, disable it and copy this rule when creating new ones.

I haven't been able to find anything in the official documentation or by playing around Guvnor.
