How can I extract an email address from a string using Ruby on Rails?

Question

I have some database upgrade to do, and I have to find email address from a description/tagline string.

String sample :

Fashion business\n\ud83c\udf38 DM for collab\n\ud83c\udf38email.adresse@gmail.com\n\ud83c\udf

This is what the string look like on Rails Console :

How can I extract "email.adresse@gmail.com" from this string? Thanks

@Nandhini it's a string made by the user, "ud83c" is a mobile smiley — Gregdebrick, Apr 11 '19 at 14:16
Can you just use regex? `([a-zA-Z0-9._-]+@[a-zA-Z0-9._-]+\.[a-zA-Z0-9_-]+)/g` Also, it'd be easier if you had some spaces between strings / emojis. — Veridian Dynamics, Apr 11 '19 at 14:20
There are well known regular expressions, just use them http://emailregex.com/ — neversleep, Apr 11 '19 at 14:23
@VeridianDynamics how can I pass the string with this regex plz ? — Gregdebrick, Apr 11 '19 at 14:31
You will have to remove the emoji characters before processing. There should be some character separating the email from other characters (usually whitespace). In your sample string it is impossible to decide if `udf38` is part of email or not. — tejasbubane, Apr 11 '19 at 16:33

Answer found in a Java post but translated to rails it would be :

string = Fashion business\n\ud83c\udf38 DM for collab\n\ud83c\udf38email.adresse@gmail.com\n\ud83c\udf

email = string.scan(/\b[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}\b/i)

email = email.adresse@gmail.com

Thanks for you answers

The extracted email is `udf38email.adresse@gmail.com` which is not expected. – tejasbubane Apr 11 '19 at 16:29
