Question

I’m too ambitious or is there a way do this

to add a string if not present ?

and

remove a the same string if present?

Do all of this using Regex and avoid the if else statement

Here an example

I have string

"admin,artist,location_manager,event_manager"

so can the substring location_manager be added or removed with regards to above conditions

basically I’m looking to avoid the if else statement and do all of this plainly in regex

"admin,artist,location_manager,event_manager".test(/some_regex/)

The some_regex will remove location_manager from the string if present else it will add it

Am I over over ambitions

Answer 1

You will need to use some sort of logic.

str += ',location_manager' unless str.gsub!(/location_manager,/,'')

I’m assuming that if it’s not present you append it to the end of the string
