  • 0

I am using Ruby on Rails v3.0.9 and I am finding the best way to retrieve the “last part” of a email string and the related web site URL (that is, the web site that provides the email service).

For example, if I have

sample_email_title@gmail.com

I would like to retrieve

gmail.com

and “transform” that so to have the following:

http://www.gmail.com

How can I accomplish that?

    You could do something like this:

    a = "my_email@gmail.com"
b = a.split("@").last
=> "gmail.com"

"http://www." + b
=> "http://www.gmail.com"

    You could do it all in one line with:

    "http://www." + "my_email@gmail.com".split('@').last

    There may be better ways, but this is fairly simple.
