While reading through another question here, on creating a URL shortening service, it was suggested to take the ID of the row, and then convert it to base 62 (0 to 9, a to z, and A to Z). Is there a standard function to accomplish this in Ruby?
Edit:
Not sure if I was clear enough.
Something like this:
123456.radix(62)
should give the base 62 of 123456.
I’m thinking of writing one, if it isn’t already there.
The to_s method in Ruby integer classes has an optional parameter specifying the base, something like:
However, it only accepts values from 2 to 36 as the radix.
This snippet might be a good starting place if you want to write your own encoder. There’s also a base62 Ruby Gem that adds methods for encoding and decoding in base62.
