Hello
in my Faq model i added a method
def calculate_score
score_faq = 0
self.votes.each do |t|
score_faq += t.score
end
self.score= score_faq
end
this method working well but i would like to use sum
def calculate_score
self.score = self.votes.sum(&:score)
end
But this new method was not working
Can u explain me why ?
Thanks
