Re: [rules-users] nested condition in from collect
You're right, it worked without the eval and I did have the import. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/nested-condition-in-from-collect-tp1637479p1646029.html Sent from the Drools - User mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] nested condition in from collect
I'm trying to determine if a user has a certain immunization on record or a
group of immunizations but when I attempt to put additional the rule will
not compile.
rule "Immunizations_Determine if a user has a valid tetanus immunization"
dialect 'mvel'
no-loop true
salience 100
when
$user : User($profile : profile)
$got : List() from collect ( UserImmunization( immunization != null,
eval( immunization.immunizationName == "Td or Tet/Dip (Tetanus/Diphtheria)"
|| immunization.immunizationName == "Tdap (Tetanus/Diphtheria & Pertussis)"
|| immunization.immunizationName == "DT (Diphtheria/Tetanus)" ||
immunization.immunizationName == "TT or Tet Tox (Tetanus Toxoid)" ||
immunization.immunizationName == "Tetanus")) from $profile.userImmunizations
)
then
System.out.println("The user has has a valid tetanus immunization ");
end
The profile contains a list of UserImmunizations.
UserImmunizations:
private Long id;
private Immunization immunization;
private Date dateReceived;
Immunizations:
private Long id;
private String immunizationName;
I'm not sure if this is a good place to use 'from accumulate'.
Is it possible to do the condition for the Immunization object within the
'from collect' or should it be evaluated separately?

[rules-users] LHS compare two lists
Hi,
I'm trying to determine if a user has the required certifications for a
position. So I'm comparing the list of required certifications to the list
of User Certifications but I'm throwing a nullPointerException even though I
check to make sure the list are not null on their respective objects. How do
I iterate between both list?
rule "Determine if the user has the required certifications"
dialect 'mvel'
no-loop true
salience 80
when
$user : User()
$profile : UserProfile($userCertifications : userCertifications,
eval(userCertifications != null)) from $user.userProfile
$position : Position($certifications : requiredCertifications,
eval(requiredCertifications != null))
exists ($certification: Certification() from $certifications and
UserCertification(certification == $certification) from $userCertifications)
then
System.out.println("The user has the required certifications");
end
public UserProfile
{
List userCertifications;
//more fields
}
public Position
{
List requiredCertifications;
//more fields
}
public Certification
{
Long id;
String name;
//more fields
}
public UserCertification
{
Long id;
Date certificationDate;
Certification certification;
//more fields
}

Re: [rules-users] Verify if an objects attribute exists
Sorry here is some additional details...I hope I'm not making this sound more
complicated than it really is but I am attempting to restrict access to view
an account based on the logged in user.
public class User
{
private Long id;
...
private UserProfile userProfile;
}
public class UserProfile
{
private Long id;
private User supervisor;
}
So I created a function called isUserMatching to determine if the
currentUser is looking at their own account or if their supervisor is
looking at an employees account:
function boolean isUserMatching(User user)
{
User currentUser = (User) Component.getInstance("currentUser");
User supervisor = (User) user.getUserProfile().getSupervisor();
boolean result = false;
if(currentUser == user)
{
System.out.println("## currentUser = user is
TRUE #");
result = true;
}
else if((supervisor != null) &&
(currentUser.getId().equals(supervisor.getId(
{
System.out.println("## currentUser = supervisor is
TRUE
#");
result = true;
}
else
{
System.out.println("## currentUser/supervisor !=
user is FALSE #");
}
return result;
}
This function works as desired but not all users have a supervisor. What I'd
like to know is how can I check if a supervisor is null so that I can
prevent passing null values into functions?
Doing this "eval (isUserMatching($supervisor))" results in an runtime error
of course when there is no supervisor.

[rules-users] Verify if an objects attribute exists
I'm having difficulty writing this rule.
Background information:
A User can have a supervisor but it's not required.
When viewing User information I want to verify that the logged in user is
either the current user or the currentUser's supervisor but I throw an
exception when the supervisor object is null on the currentUser.
The target is the User being viewed and I have a global object that is the
current user. How can I check to see if the supervisor exists before
evaluating if the currentUser and the supervisor are equal?
rule 'CanViewUserData'
dialect 'mvel'
when
$user : User()
$supervisor : User( ) from $user.userProfile.supervisor
$check: PermissionCheck(target == $user, action == "viewUserData")
eval(isUserMatching($user)) || eval (isUserMatching($supervisor))
then
System.out.println("The currentUser CanViewUserData");
$check.grant();
end

[rules-users] Drools 5.1.1 KnowledgeAgent and SecurityRules
I recently upgraded from drools guvnor 5.0.1 to 5.1.1 but I haven't seen any examples on how to change securityRules now that RuleBase has been replaced with KnowledgeBase. Originally I had... https://127.0.0.1:7002/drools-guvnor-5.0.1/org.drools.guvnor.Guvnor/package/Security/LATEST"; local-cache-dir="/tmp/" poll="60" auto-create="true"/> I tried to leave this way but then i get an error but the 5.1.1 guvnor secures the URL so I get the following: RuleAgent(default) EXCEPTION Response: '401: Unauthorized' for url: ...

Re: [rules-users] create .pkg file with or without BRMS
I think the DroolsCompilerAntTask generates a serialized RuleBase, not a
Package.

Re: [rules-users] How to get the Eclipse Rules View to show my rules?
Thanks for your reply. After converting to a Drools project, I now get the "Only a type can be imported" errors on all my import statements in the DRLs (and other errors as consequences of that). I compare the structures of my project to the examples and can't find much different. What do you think I'm still missing? (As a Java project, the project still works fine. All my jUnit tests still run ok) Thanks.

Hello everyone, I'm using Drools 4.0.3 and Eclipse 3.3. The Rules View shows the rules in the drools-examples-drl package, but not my own rules. Is there any configuration or registration needed for the Rules View to recognize my rules? The rest of Drools work fine.

[rules-users] Can a rule be assigned both agenda-group and ruleflow-group ?
Hi everybody: I would like to use Drools to capture validation logics that will be shared at UI level and back-end level. That is, I need to fire a specific rule on-demand to validate a field input and fire it again as part of the final validation. To fire a specific rule, I use the agenda-group attribute. To fire it again as part of a larger group, I then try to create a ruleflow. I found that if I add a ruleflow-group to a rule, it's can no longer be fired by setFocus(). Is that normal, or I did something wrong? I thought of creating a ruleflow for each rule, but that sounds like a hack to me, Drools probably offer a more elegant solution (I'm only 2 wks into Drools). What is best way to implement my problem: to fire a rule individually and to fire it again as part of a group?
