Validating a legal subdomain
I have a Rails app that uses subdomains as account keys. Users name their own subdomains. How can I validate those subdomains as legal? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

How can I validate those subdomains as legal?Just like you would verify a user login. The subdomain then becomes part of the login procedure. You store it in a table and you "authenticate" the domain in a before_filter.

I think what Jeff meant is how to validate the subdomain as a normal combination of letters and integers without a bunch of strange keys. He''s not talking about authentication, he''s talking about validation. I''ll post here if I get this going Jeff. I''m also working on a way. It looks like it will have to be a regular expression.

I eventually settled on a regex that permits only letters, numbers and
hyphens. Close enough for my needs:
validates_format_of :subdomain,
:with => /^[a-zA-Z0-9\-]*?$/,
:message => ''accepts only letters, numbers
and hyphens''
Hope that''s helpful!

That is pretty much what I was going to recommend.
