Question

I come from a PHP and Python/GAE background and am new to RoR. Typically I’d have a global variable set up containing my unsecure and secure webpage’s url, for use when templating. For example, if I want to link to an image, rather than saying img src=”www.mysite.com/images/img1.png” I can use img src=”{{ unsecure_url }}images/img1.png”.

I’m thinking the best way to do this in RoR is to add the following to my application_helper. Is that valid?

def unsecure_url
  "http://localhost:3000/"
end

def secure_url
  "https://localhost:3000/"
end

And how can I switch between localhost and production, depending on whether I’m in a local environment or not?

If you use the pre-existing helpers, they should generate relative links for the current protocol and domain.

Take a look at link_to, and image_tag.
