I want to create a test that returns either true or false for email

  • 0

I want to create a test that returns either true or false for email handling.

For now, if the email address starts with r+ then it’s true otherwise it’s false. This will help our server ignore a lot of the SPAM we are getting hit with.

Examples:

r+kldslkadslkadslk@site.com .. true
r+123123312@site.com .. true
vigraaaa@site.com .. FALSE

What’s the most efficient way to handle this with Rails/ruby/regex?

Thanks

    This will match:

    /^r\+.*@site.com$/

    Examples:

    >> 'r+kldslkadslkadslk@site.com' =~ /^r\+.*@site.com$/ #=> 0
>> 'vigraaaa@site.com' =~ /^r\+.*@site.com$/ #=> nil

    Since everything that isn’t nil or false is truthy in Ruby, you can use this regex in a condition. If you really want a boolean you can use the !! idiom:

    >> !!('vigraaaa@site.com' =~ /^r\+.*@site.com$/) #=> false
>> !!('r+kldslkadslkadslk@site.com' =~ /^r\+.*@site.com$/) #=> true
