Putting Date and 1.month.ago together?
Just 1.month.ago is enough, you don't need to prepend Date.today to 1.month.ago because 1.month.ago starts from today
You have mistake in your Date syntax, you might want to use something like this:
def self.last_month # Show only products of last month. where(:purchase_date => 1.month.ago.beginning_of_month..1.month.ago.end_of_month)enddef self.this_month # Show only products of this month. where(:purchase_date => Date.today.beginning_of_month..Date.today.end_of_month)end
Maybe:
def self.this_month where(:purchase_date =>(Date.today - 1.month)..Date.todayend
