Question

I am new to Ruby and Ror so any guidance would be awesome. I have a function:

def self.insert_feed_product_scores(id, low, high)
  avgScore = low.to_s + " - " + high.to_s
  @feedProduct = FeedProduct.find(id)
  @feedProduct.avg_score = avgScore
  @feedProduct.save
end

If for some reason the id that I pass in isn’t found, I notice I get this error, thats fine:

ActiveRecord::RecordNotFound: Couldn't find FeedProduct with id=999999

I could write some logic and check if there is a score and there is something found before I save, but it just doesn’t seem like the Ruby way of doing things…should I just write in logic to validate or is there some Ruby/Ror way of doing things?

Thanks

If you want to track the error message and log properly, follow @lucapette answer. Else

def self.insert_feed_product_scores(id, low, high)
  @feedProduct = FeedProduct.find(id) rescue return false
  @feedProduct.avg_score = "#{low} - #{high}"
  @feedProduct.save
end
