Rails - Convert number to array

Question

Let's say I have a number 5

How would I convert this to an array [1, 2, 3, 4, 5]?

The application here is I have an instance variable @pages and I want to create a pagination view.

pages = 5
array_of_numbers = (1..pages).to_a

(1..pages) will give you a Range object and to_a will convert it into an array.

pages = 5 (1..pages).each { |n| puts n }

You have a lot of other ways in older answers. I guess isn't necessary to create a new question for that.

This won't return an array. It will just print the nos.
