Question

I want to make an email validation that only accept emails from my college so I wanted to know how to do that.

    email_regex = /\A[\w+\-.]+@[a-z\d\-.]+\.[a-z]+\z/i

validates :email, :presence => true,
                  :format   => { :with => email_regex },
                  :uniqueness => { :case_sensitive => false }

That is currently how my validation looks like so I wanted to know how I could make it only accept .edu type email addresses.

Answer 1

The exact regex is:

email_regex = /\A[\w+\-.]+@yourcollege\.edu\z/i

Like user482594 mentioned in the comments, just thought I would point out that you need the \ before the ..
