How do I get the host and protocol in a Rails applicaiton

Question

Feel pretty dumb with this question.

In a Rails Model, I want to be able to find out the host and protocol. For example, if I am in a test environment it would return http://localhost:3000/ and if I was in production it would return something like http://my.application.com/?

Is this even possible?

Thanks!

Answer 1

Request.host

http://api.rubyonrails.org/classes/ActionController/Request.html#M000712

Answer 2

you can get full uri (http://localhost:3000/ or http://my.application.com/ etc) with request_uri

http://apidock.com/rails/ActionController/AbstractRequest/request_uri

Answer 3

You can get those values in your controllers (request.host, request.port etc.).

You'd have to give that to your models via parameters as the request object is only available in the controllers.
