Using Morph Labs' Appspace to deploy a site means no automated way to redirect 'myapp.com' to 'www.myapp.com' (and no access to .htacess).
Is there an in-rails way to do this? Would I need a plugin like subdomain-fu ?
More specifically, I'm trying to do something like:
- 'myapp.com' => 'www.myapp.com'
- 'myapp.com/session/new' => 'www.myapp.com/session/new'
Basically, I always want the 'www' subdomain prepended on every request (because the SSL cert specifically has a common name of 'www.myapp.com').

Maybe something like this would do the trick:
ReplyDeleteclass ApplicationController < ActionController::Base
before_filter :check_uri
def check_uri
redirect_to request.protocol + "www." + request.host_with_port + request.request_uri if !/^www/.match(request.host)
end
end
Carson's answer works great.
ReplyDeleteHere's the code to go the other way (www -> no www)
before_filter :check_uri
def check_uri
if /^www/.match(request.host)
redirect_to request.protocol + request.host_with_port[4..-1] + request.request_uri
end
end
This worked great for me. I did make one small addition as I only wanted this behavior in my production environment:
ReplyDeletedef check_uri
redirect_to request.protocol + "www." + request.host_with_port + request.request_uri if !/^www/.match(request.host) if Rails.env == 'production'
end
I know this is answered, but I thought everyone else should know about the CodeRack: Canonical Host solution. This is really nice as it allows for env specific redirects. http://coderack.org/users/tylerhunt/middlewares/6-canonical-host
ReplyDeleteI had to change Carson's answer to get this to work in Rails 3. I replaced request.uri with request.fullpath:
ReplyDeleteclass ApplicationController < ActionController::Base
protect_from_forgery
Rails.env.production? do
before_filter :check_url
end
def check_url
redirect_to request.protocol + "www." + request.host_with_port + request.fullpath if !/^www/.match(request.host)
end
end
