Escaping Apostrophes Using Gsub

Question

I\'m working in Ruby and I\'m trying to escape \' characters to \\\' so that I can use them in SQL. I\'m trying to use gsub, but it do

Answer 1

Someone else had this very issue, due to a special meaning/interpretation in Ruby's regex.

\' means $' which is everything after the match. Escape the \ again and it works

See this answer.

Does this work?

"this doesn't work".gsub /'/, '\\\\\'' => "this doesn\\'t work"

Answer 2

You must escape the \ and the '. When you need the ' in the result, why not define the result with "

puts "this doesn't work".gsub /'/, "\\\\'" #=> "this doesn\'t work"

\ must be escaped anyway.
