Only to find that request.subdomains.first now equals
account.subdomain - which is NOT the case before the
"MyMailer.deliver_signup_notification" method. So url_for changes the
request object - which I personally dislike. Is there a work around
for this?
This passes and as far as I can see url_for doesn't modify anything.
Of course it may be something to do with a plugin you have. Can you
try something similar and let us know the results? Also, it would be
good to know which version of Rails you're running.
