How can I use the results of a view as a condition in a rule?
I have rule that fires off a daily digest email with contents from a view (using Views Rules). The view simply returns nodes that have a specific field value. When the view doesn't return any nodes, the rule still fires off what is essentially an empty email. I want to prevent this. I need a condition like "View has no results" (negated)… but I don't see anything like that. What's the workaround?
