Hiding data in models

In all our models related to users, there is a boolean field is_false . What would be the most optimal way to hide all users with is_false = true directly within the model itself? It’s easy to filter this out in conditions, but many users constantly forget to do so.

dimension is_test {
label: “Is Test”
type: “truefalse”
hidden: false
definition: @sql {{ #SOURCE.IS_TEST }};;

We’ve done this by using a query model instead of a table model, and putting the condition in the query so it only pulls data that satisfies the condition, not sure if that achieves what you’re looking for.
