Hi all,

Is it possible to get the subdomain of the request from the action  
controller? If so, how do we get the subdomain from Rails action  
controller? I tried to look at the Rails guide about this but can not  
find any information on this.

Thank you very much in advance for your help and assistance.

Kind regards,  
Joshua

Just use subdomain\_fu plugin [GitHub - mbleigh/subdomain-fu: A new plugin approach to attempting to solve the usage of subdomains in linking and routing in Rails projects.](http://github.com/mbleigh/subdomain-fu)  
[http://github.com/mbleigh/subdomain-fu](http://github.com/mbleigh/subdomain-fu)You’ll get ‘current\_subdomain’  
method to use in controllers
