rails get app root/base url

Question

In my app I have a few APIs that under api domain. Now in one of the API I want to generate a url that pointing to the main domain, say

test.com/blabla...
<         


        

Answer 1

Just so that it's useful to someone else , i came across this today

request.base_url

gives the full path in local as well as on live .

request.domain

gives just the domain name so it sometimes kinda breaks the link while redirecting
