ActiveRecord Find By Year, Day or Month on a Date field

Question

I have an ActiveRecord model that has a date attribute. Is it possible to utilize that date attribute to find by Year, Day and Month:

Model.find_by_year(201         


        

Answer 1

In your Model:

scope :by_year, lambda { |year| where('extract(year from created_at) = ?', year) }

In your Controller:

@courses = Course.by_year(params[:year])
