Query Filter missing

[hakunin]

I still have to write:

q = ClickRecord.all.webapp_id(metric.webapp_id)
q._query.addFilter(:created_at,
        Query.FilterOperator.GREATER_THAN,
        Long.new(metric.last_processed_event_time)
      )
q.run.each { |click|
  metric.visit(click)
}

It would be nice to have greater_than method instead, ideally with overloaded version for primitives:

ClickRecord.all.
    webapp_id(metric.webapp_id)
    greater_than(:created_at, metric.last_processed_event_time).
    run.each { |click|
  metric.visit(click)
}
