Question

I have a simple rails app that is like an event system which has a start_at field and an end_at field. I want to be able to display the events whose start_at month fall at this present month. I defined a scope for this like below:

scope :this_months_event, lamda{where("start_at = ?" Time.zone.now.month)}

Whenever I try this out in my console window I get an empty array. I observed that the month of the start_at field is not being fetched so it cannot find the start_at month, so it returns empty instead.

Does anyone know a good way to do this or how can I pass the start_at month so that when I call Event.this_months_event, I get all the events for this present month and if possible a scope to fetch past events and another to fetch present events.

Your condition says that start_at should be exactly the value of Time.zone.now.month, which, as of this writing is 8. You want to compare start_at with the beginning and end of the month:

scope :this_months_event, lambda { where("start_at >= ? AND start_at <= ?", 
  Time.zone.now.beginning_of_month, Time.zone.now.end_of_month) }
