Filter data in ruby on rails by subdomain

Question

I have 2 tables news and news_type. Also I have 3 base types for news: politic, technology and sport. How I can filter this data by subdomain?

For example:

If I go to example.com I get all news in my home page

If I go to sport.example.com I get all news with type sport

And so on.

Answer 1

In your routes.rb file, you can provide constraints on the path. For example:

# routes.rb
...
get "/" => "sports#index",  constraints: { domain: "sport.example.com" }
get "/" => "tech#index",  constraints: { domain: "tech.example.com" }
root :to => 'static#index'

This would route

• sport.example.com to the index action within SportsController
• tech.example.com to the index action within TechsController
• example.com to the index action within StaticController
