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.

You have a lot of other ways in [older answers](https://stackoverflow.com/questions/191329/correct-way-to-populate-an-array-with-a-range-in-ruby/6587096). I guess isn't necessary to create a new question for that. – Sebastián Palma Dec 22 '18 at 13:13
This won't return an array. It will just print the nos. – mridula Dec 22 '18 at 15:20
