Function selectattr

pub fn selectattr(
    state: &State<'_, '_>,
    value: Value,
    attr: Cow<'_, str>,
    test_name: Option<Cow<'_, str>>,
    args: Rest<Value>,
) -> Result<Vec<Value>, Error>

Creates a new sequence of values of which an attribute passes a test.

This functions like select but it will test an attribute of the object itself:

{{ users|selectattr("is_active") }} -> all users where x.is_active is true
{{ users|selectattr("id", "even") }} -> returns all users with an even id
