How to replace space with %20 in rails

Question

What I do

str= "  John   Smith Beer "
str.tr(" ", "%20")
"%%John%%%Smith%Beer%"

It doesn't replace it with "%20". How to fix it?

Assuming this is to be used for a URL ... you could just leave the space in. Browsers will do this conversion for you before submitting the request. Otherwise - the solution from MilesStanfield is most appropriate. — Jon, Jan 06 '16 at 08:39
Rails usually handles this conversion. What are you trying to do? — Stefan, Jan 06 '16 at 08:40
Yes on browser its work...Issue which I face is that this is ans API and on mobile video this doesn't work because of spaces... — Haseeb Ahmad, Jan 06 '16 at 09:37

In ruby 3, use `require 'erb'; ERB::Util.url_encode('green book')` – Sean Lerner Nov 27 '21 at 20:16
