Validates url format in Ruby on Rails

Question

I'd like ask if there's a way to validate a string as an url or email at the same time?

for example:

validates_format_of :string, :with => [url_regex, email_regex]

string = 'http://domain.com' => valid
string = '[email protected]' => valid

thanks in advance!

You need your own validate method, i don't think rails validation provide OR option here — Naveed

According to the Rails API you cannot pass two regexes in an array or something. The solution would be to create a regex that matches both URL's and email addresses or - as Naveed suggests - create a custom validation. That being said, I don't think you can validate a URL with a regex.

thanks but what i wanted was to check if the string is an url or email at the same time

In that case you would have to create a regex that matches both URL's and email addresses. You cannot pass two regexes.

thanks mischa and naveed. i guess i have to create my own validation after all. i just think that validates_format_of is so much cleaner.

@cece: And use URI from the standard library to help you validate the URL.
