Ruby on rails application shows files index instead of the app - ruby-on-rails

Question

I would like to deploy a Ruby on Rails application on the web, and for that matter I have used/deployed the following tools:
Capistrano, to deploy the app files to the target location
The Phusion Passenger module for Apache
I have enabled the Passenger module through sudo a2enmod passenger. I have also installed the passenger gem through the gem installer, and added it to the Gemfile of my rails app.
I have then created an Apache virtual host for the app 'myapp'.
myapp.conf
Alias /myapp /var/www/myapp/current/public
<VirtualHost *:80>
DocumentRoot /var/www/myapp/current/public
SetEnv SECRET_KEY_BASE 592da***************************************
<Directory /var/www/myapp/current/public>
PassengerEnabled on
PassengerResolveSymlinksInDocumentRoot on
PassengerAppRoot /var/www/myapp/current
PassengerAppType rack
PassengerStartupFile config.ru
Allow from all
Options -MultiViews
Require all granted
</Directory>
</VirtualHost>
The virtual host work, but when I access the URL in a web browser, it shows the files index in /var/www/myapp/current/public instead of the actual app. The reason for this seems to be that passenger is not started, but I can't figure out why. I have tried to tweak the myapp.conf file to help apache and passenger detect the app, but without success.
Could anyone help me fix this? Thanks in advance.
Additional info: the app is deployed on a Raspberry Pi 3 with Raspbian Jessie as OS.

Try this .This is for sub uri deployment.Error is because PassengerRuby path has not been mentioned. Also go through this link
https://www.phusionpassenger.com/library/deploy/apache/deploy/ruby/.
Alias /myapp /var/www/myapp/current/public
<VirtualHost *:80>
SetEnv SECRET_KEY_BASE 592da***************************************
PassengerRuby /path-to-ruby /* replace this with your ruby path
<Location /myapp>
PassengerBaseURI /myapp
PassengerAppRoot /var/www/myapp/current
PassengerEnabled on
</Location>
<Directory /var/www/myapp/current/public>
