Subdomains are a great way to organize different parts of your app. You might have an api
subdomain, news
subdomain, etc.
routes.rb
constraints subdomain: 'my-subdomain' do
# add routes
end
development.rb
Add new hosts to your development.rb configuration.
config.hosts << "my-subdomain.my-domain.local"
Development Environment
Add development subdomain(s) to your /etc/hosts file so it routes to your development server
127.0.0.1 my-subdomain.my-domain.local
Don't forget to add port 3000! You'll go this url in your browser. my-subdomain.my-domain.local:3000
Heroku
DNS Configuration
Add a CNAME
record for each subdomain in your DNS configuration.
Use the domain name
and DNS Target
from Heroku.
That's it! You should be good to go.
