8:17 a.m.
Have a look at this class:
drools-repository/src/test/java/org/drools/repository/AssetItemTest.java
The doc in the selectors.properties file is talking about properties of
AssetItem - however, don't take it literally - a rule uses a getter,
hence it's sufficient to have such a method in the AssetItem class
instead of a regular field. So if you see a getStateDescription method
you can use stateDescription - that's at least my understanding.
So looking at AssetItem and VersionableItem I see following candidates
for a selector:
name
createdDate
versionNumber
creator
lastContributor
checkinComment
categories (java.util.List)
categorySummary (space separated string of categories)
precedingVersion
format
stateDescription
lastModified
dateEffective
dateExpired
description
succeedingVersion
content
title
disabled
Let's get back to your original question (I've answered it already in jira):
Try this out:
package org.drools.guvnor.server.selector
import org.drools.repository.AssetItem
import org.drools.repository.CategoryItem
import org.drools.guvnor.server.selector.Allow
rule 'select all rules assigned to myCategory'
dialect 'mvel'
when
ai : AssetItem()
CategoryItem(name == "myCategory") from ai.categories
then
insert (new Allow( ) );
end

Hi Jaroslaw,
I voted for https://jira.jboss.org/jira/browse/GUVNOR-109
and added the following comment:
<<
+1 for this request.
The ability for users to choose among which selectors are available is
awesome.
Here's an extra requirement that I am bringing forward, not sure what
the complexity on this is:
The list will be populated based on user permissions of some kind.
ie, not all the users can deploy production rules, but all can deploy QA
rules, for example.

I have also created https://jira.jboss.org/jira/browse/GUVNOR-392 for
including categories as a field for filtering.
Regarding your tip on using the 'status' field, I was planning for the
workaround, though it messes with the actual value of this field which i
was planning to use.
Based on our environment, we might actually use the "author" field as
currently there will not be many authors and we are tracking
functionality by using categories anyways.
I have the following questions that are still unanswered:
1) I am trying to figure out where the code for "statusDescription" is?
2) You have suggested 'categorySummary' - was wondering where these
fields are configured.
3) the minimal documentation in selectors.properties tells only about
the fields status, lastModified date and author, and ends with etc.
Could one of the devs kindly post ALL the fields that could be used?
Regards,
Prem

Hi,
you may vote for this one ;)
https://jira.jboss.org/jira/browse/GUVNOR-109
So far I have successfully used 'stateDescription' and 'creator',
for sample rules look at this:
https://jira.jboss.org/jira/browse/GUVNOR-108
Haven't tried to select by category - how about 'categorySummary'?
Cheers,

Hello everyone,
I am trying to create a custom selector, based on certain
properties such as "categories" (primary property) and others
such as status and author.
from the examples in selectors.properties, I could not see a way
to create using categories. In that file, some of the field
described are statusDescription, lastModified, creator, etc
I was trying to find the complete list of all fields that could
be used to filter the rules.
I dug into the code and came across "categoryReference" in
VersionableItem.java. Is this the variable that stores the category?
Since a rule can have multiple categories, how does this pan
out? Is this a Collection?
Also, where does the string "statusDescription" get tied in to
the status of a rule? This one throws me off, since it is a
valid field, but I cannot understand how it is being set.
If any of you could share examples where you have done custom
selectors either in java or in drl, that would be awesome.
Thanks,
Prem
