Francesco, it’s cleaner if you just let the environtment configs handle the default_url_options

Hello,

thanks for the infos, you solved my issue, now I’m using this in my application.rb and it works well for my needs.

config.action_mailer.default_url_options = { :host => Rails.env == “production” ? ‘domain.com’ : ‘localhost:3000′ }

@Sandy,

While that would work, the before_filter approach has the added benefit of being dynamic to the environment Rails is currently running in. This gives you the flexibility to have links in development point to development, not production.

Or put it in environment.rb

config.action_mailer.default_url_options = { :host => “example.com” }
