Subject: [rules-users] Dynamic attribute in Guvnor


Hi,

We have a scenario as below, 

Here is what we want to achieve. Let’s say we want to have following rule:

When AssetType = DSTR Then Decision = Granted.

I can have AssetType as static class or attribute in the model. But this may
limit our ability to handle new information. Let’s say now I have rule to
restrict access to a specific metadata asset like:

When AssetID = 8-XXX-1234 and Group<>’HR’ then Decision = Denied.

If we don’t have AssetID, then no one can define that rule until we change
the code. What we really want is if Drools can do something like this:

When DynamicAttribute(“AssetID”) = 8-xxx-1234and Group<>’HR’ then Decision =
Denied.

Any one has implemented anything similar to this before??

Thanks,
BB
