问题
I have an application in rails and hosted on Heroku. Now , what I want is that the application can be accessed from 2 different domains, when the application is accessed from suppose a.com it should have a specific frontend, and when accessed from b.com it should display some other frontend. The backend should be same for both. To achieve this I suppose there is only one way I guess, which is to have two different application with same backed code, and same database(I am using PostgreSQL). I need some help on how Do I achieve this, if not, then some other alternative.
回答1:
You could have only one app for both if it's easier for you. I would then suggest you configure config/routes.rb to respond differently according to the domain name.
See another answer about it here: Rails routing to handle multiple domains on single application
And the Advanced Contraints in Rails here: http://guides.rubyonrails.org/routing.html#advanced-constraints
