localhost on rails

Question

hi, I am sending an email that contains a link to my website. I want to be able to test it locally and be able to move the scripts around to different hosts easily.

In my email right now I use the following:

  <%= url_for(:host => 'localhost:3000', :controller => "user_activations", :action => "show", :id=>@id, :confirm=>@passcode) %>

This works for when testing locally but will obviously fail for production. Is there an easy way to have rails (or ruby) detect what the current host is? I'm thinking something like $_SERVER of php.

I realize I can use some logic using my environment variable but I would like to avoid this.

Thanks

Answer 1

I define a constant 'HOST' in my environment.rb that sets my host. Alternatively you can use request.host or request.domain.

Answer 2

in environments/development.rb

config.action_mailer.default_url_options = { :host => "localhost", :port => 3000 }

in environments/production.rb

config.action_mailer.default_url_options = { :host => "www.xyu.at" }

and use tests with rspec-email :)
