The simplest way to do this is probably in the login action itself.
Here's a sample (in UsersController or equivalent):
def login
hobo_login do
if current_user.administrator? && @ipAddress != "196.255.255.255"
flash[:error] = "You cannot have access from your current location."
self.current_user = nil
redirect_to root_url
end
end
end
Basically, you can override what gets rendered from inside the block
passed to hobo_login; current_user will already be set, so if you need
to log the user out just set it to nil.
