How to add percentage and . in search string rails constrains. It's giving No route matches [GET] (Actually it's a GET Request)

Here is my constraint 

get "/external_id/:external_id",
controller: "XXXXXXX",
action: "show_by_login_name",
constraints: { external_id: /[a-zA-Z0-9.]%+/ }

Please modify your regex to use the following code

/[0-z\.\%]+/

Explanation:

Your current regex /[a-zA-Z0-9.]%+/ reads as:

  1. match a single character from the list: [a-zA-Z0-9.]
  2. match one or more occurrences of %

So, if your :external_id is: something%else, the pattern matches only g%.

In the future, if you are not sure about regex, you can always test it with tools such as regex101

  • @KrishnaMaheswara when you want to send `%` in the URL, please use `%25` instead (https://stackoverflow.com/a/17342786/2039726). Is it working then? – MrShemek Mar 26 '19 at 16:49
