[rules-users] Data comparing in CONDITION column decision table
Hi, Can we use a data value of another object in the condition column of a Spreadsheet. For example: I have two data types(POJOs) one com.bank.Customer and other com.bank.Account in the rules I want to check whether the value entered for a particular field in Customer class is equal to the value entered for the corresponding field in the Account class. eg Customer.accType = Account.accType() How can we achieve this using Decision table (CONDITION Column). I have tried this: |RuleTable |Discount |CONDITION |CONDITION | ---+| |$a : Account |$c : Customer | ---+| | |type == "$param" --+---+ | Discount |Account|Type| | Rules | || |--+---+| |1 | |$a.getType()| |--+---+| |2 | |$a.getType()| |--+---+| |3 | |$a.getType()| |--+---+| |4 | |$a.getType()| |--+---+| |5 | |$a.getType()| |--+---+| |6 | |$a.getType()| |--+---+| But it won't work. It would be great if somebody could help me on this.

Line breaks were lost in transit, but I think that you should remove the quotes from type == "$param" if you insert an expression $a.getType(). -W On 15/03/2012, Sumeet Karawal wrote: > > Hi, > > Can we use a data value of another object in the condition column of a > Spreadsheet. > > For example: I have two data types(POJOs) one com.bank.Customer and other > com.bank.Account > > in the rules I want to check whether the value entered for a particular > field in Customer class is equal to the value entered for the corresponding > field in the Account class. eg Customer.accType = Account.accType() > > > How can we achieve this using Decision table (CONDITION Column).

Re: [rules-users] Data comparing in CONDITION column decision table
when I do this I am getting the below error:
Exception in thread "main" java.lang.RuntimeException: Unable to Analyse

Howerver, when I include the following in the decision table:
|
|RuleTable
|Discount
|
|CONDITION |CONDITION |
|---+|
|$a : Account |$c : Customer |
|---+|
|type |type == $param

|current||

|savings||

|current||
|---+|
|savings||

|current||
|---+|
I am getting correct result. But here I don't want to check for the type
entered for Account class.
The generated drl is like this:
rule "Discount_10"
when
$c : Customer(type == $a.getType(), accno == 1001)
then
$c.setDiscount(1);
end
How to make changes to the decision table entries to get a drl of this
kind:
rule "Discount_10"
when
$a : Account()
$c : Customer(type == $a.getType(), accno == 1001)
then
$c.setDiscount(1);
end
Thanks,
Sumeet

Re: [rules-users] Data comparing in CONDITION column decision table
After doing the changes, its taking the rules as: rule "Discount_10" when $a:Account(type == $a.getType(), accno == 1001) $c:Customer then $c.setDiscount(1); end and if I put it as $a: Account() $c: Customer(), it takes the rules as: rule "Discount_10" when $a:Account(type == $a.getType(), accno == 1001) $c:Customer() then $c.setDiscount(1); end Both these throw error.. neither putting the $c:Customer before $a:Account is getting executed.

Re: [rules-users] Data comparing in CONDITION column decision table
The documentation for 5.3.0 says To include a pattern without constraints, you can write the pattern in front of the text for another pattern. but it does not work with 5.2.0 and (likely) later versions. As a workaround, re-insert the Account column and use a redundant condition that is certainly true for all facts. I'll have to look into this. -W On 15/03/2012, Sumeet Karawal wrote: > Hi Wolfgang > > any other way to achieve this.

Re: [rules-users] Data comparing in CONDITION column decision table
Hi
Instead of using a workaround, did you have a look to rule templates ?
- under guvnor :
http://docs.jboss.org/drools/release/5.4.0.Beta2/drools-guvnor-docs/html_single/index.html#d0e1143
- drl :
http://docs.jboss.org/drools/release/5.4.0.Beta2/drools-expert-docs/html_single/index.html#d0e7501
You should be able to do exactly what you are trying to do, but properly, like
that :
template header
field
accno
package range;
template "Discount"
rule "Discount @{row.rowNumber}"
when
Account( $v : @{field} != null )
$c : Customer( @{field} == $v , accno == @{accno} )
then
$c.setDiscount(1);
end
end template

Re: [rules-users] Data comparing in CONDITION column decision table
This is true, but be aware that if a cell value in the Template data is
empty the whole Fact Pattern is omitted.
For example:-
rule "Discount @{row.rowNumber}"
when
Account( $v : @{field} != null )
$c : Customer( @{field} == $v , accno == @{accno} )
then
$c.setDiscount(1);
end
If "field" is empty neither "Account" or "Customer" will be included in the
generated DRL.
If "accno" is empty "Customer" will not be included in the generated DRL.
This may have an impact on what you want to achieve.
With kind regards,
Mike

Re: [rules-users] Data comparing in CONDITION column decision table
Thanks for the warning, some old bugs appears clearer now !!!
Is it planned in a near future to only exclude the constraint and not
the whole fact pattern ?
To me, it seems more accurate to do this way.
Le 19/03/2012 22:57, Michael Anstis a écrit :
This is true, but be aware that if a cell value in the Template data
is empty the whole Fact Pattern is omitted.
For example:-
rule "Discount @{row.rowNumber}"
when
Account( $v : @{field} != null )
$c : Customer( @{field} == $v , accno == @{accno} )
then
$c.setDiscount(1);
end
If "field" is empty neither "Account" or "Customer" will be included
in the generated DRL.
If "accno" is empty "Customer" will not be included in the generated DRL.
This may have an impact on what you want to achieve.
With kind regards,
Mike

Re: [rules-users] Data comparing in CONDITION column decision table
To be honest there are no plans.
Templates are implemented internally as MVEL templates and hence String
manipulation.
At this level concepts of "Pattern" and "Constraint" have no meaning and
hence it is next to impossible to determine what impact a missing parameter
value has.
