Ruby code adding single \ to escape #, instead of adding \\

Question

ruby adding single \ to escape # instead of double backslash

for example, the # in string sd@# is preceded with single \ like this sd@\# automatically. I think it should add \\ (double backslash) to escape #.

Is it a bug in ruby syntax? if not is there a way to escape it manually

Please help

To be honest, I don't understand your question at all. You don't even have to escape `#` in Ruby strings. — Marek Lipka, Jan 08 '20 at 07:10
I am not escaping it manually, I am working on react-on-rails project, Whenever I submit the string ''sd@#'' from the react form, the string gets converted into "'sd@\#'" (ruby adds a single \ instead of \\\) on ruby side and it becomes an invalid string. — Benison, Jan 08 '20 at 07:18
Are you sure Ruby does this? What gets passed in the params? — Marek Lipka, Jan 08 '20 at 07:22

You can use a single \to escape #. Also, there is no need for escaping # in strings. Both mystring# and mystring\# will give output mystring#

apologies for not being clear, But the problem here is the string is being sent to the service as json: {"description"=>"sd@\#"} which is an invalid json – Benison Jan 08 '20 at 07:23
_"there is no need for escaping # in strings"_ – unless you want to suppress interpolation, e.g. `"#$$"` and `"\#$$"` give quite different results. – Stefan Jan 08 '20 at 16:02
Better you should use JSON.generate() if you want to pass it as json – Albin Mathew Jan 09 '20 at 11:42
