Question

I am using Ruby on Rails 3.2.2 and I would like to check if a Integer is greater than 0 and, more in general, if a Integer is greater than another Integer.

There is some Ruby or Ruby on Rails method to make that “easily” / “efficiently”?

---

Note: I would like to use / state that method in my view files and I think, if that method do not “exist”, it could be better to state a “dedicated” method in my model or controller file and use that method in my views.

Answer 1

As shown here:

a = (print "enter a value for a: "; gets).to_i
b = (print "enter a value for b: "; gets).to_i

puts "#{a} is less than #{b}" if a < b
puts "#{a} is greater than #{b}" if a > b
puts "#{a} is equal to #{b}" if a == b

You can use standard Ruby within your views between <% and %>. And yes, you could implement a helper do to the check and use that helper method in your view.
