Let say you want to automate your workflow.
Like everyone you might search, ask your friends/colleague to give you some recommendation.
After researching you’ve shortlisted the app list down to two.
Those two of them has same feature, design, pricing, everything else except User Experience (UX)
One has a Generic UX while the other is a personalised UX
Needless to say that we would go with the personalised app ?
What’s better personalization than to offer an option to customized the sub-domain of our application to our customers.
Companies like Slack, BaseCamp does that :)
Here’s how to setup and manage your Rails app to handle multiple subdomains.
Step 1 - Configure your DNS
All you need to do is set up a Wildcard A Recordand point it to your server.
Step 2 - Configure your Apache/ngix
We have configured our DNS to send all request to our server.
Now we need to handle it in the web server.
Here’s the config for Apache (it just accepts all incoming request for that domain).
<VirtualHost *:80> ServerName example.com ServerAlias *.example.com </VirtualHost>
Step 3 - Initialize Application Controller
class ApplicationController < ActionController::Base before_filter :set_current_account private def set_current_account @current_account = request.subdomains.first end end
Step 4 - Custom Controller
class LoginController < ApplicationController def index render :json => @current_account end end
Let your customers have a subdomain.
