Production environment configuration in Ruby on Rails - Mini Project: Build & Apply

Production Environment Configuration in Rails

📖 Scenario: You are preparing a Ruby on Rails application for deployment to a live server. Proper configuration of the production environment is essential to ensure the app runs efficiently and securely.

🎯 Goal: Configure the Rails production environment by setting up caching, asset compilation, and logging level to optimize performance and security.

📋 What You'll Learn

Create the production environment configuration file

Set caching to true

Enable asset compilation

Set the logging level to :info

💡 Why This Matters

🌍 Real World

Rails apps need a production configuration file to run properly on live servers with optimized settings.

💼 Career

Understanding production environment setup is essential for Rails developers deploying applications to real users.

1

Create the production environment configuration file

Create a file named production.rb inside the config/environments directory. Inside this file, start with the line Rails.application.configure do and end with end.

Ruby on Rails

Rails.application.configure do
  # Your code here
end

Need a hint?

This file controls settings specific to the production environment.

2

Enable caching in production

Inside the production.rb file, add the line config.action_controller.perform_caching = true to enable caching.

Ruby on Rails

Rails.application.configure do
  # Enable caching
  # Your code here
end

Need a hint?

Caching improves performance by storing frequently accessed data.

3

Enable asset compilation

Add the line config.assets.compile = true inside the production.rb file to allow Rails to compile assets on the fly.

Ruby on Rails

Rails.application.configure do
  config.action_controller.perform_caching = true
  # Enable asset compilation
  # Your code here
end

Need a hint?

This setting allows Rails to serve assets if precompiled assets are missing.

4

Set logging level to info

Add the line config.log_level = :info inside the production.rb file to set the logging level to info.

Ruby on Rails

Rails.application.configure do
  config.action_controller.perform_caching = true
  config.assets.compile = true
  # Set logging level
  # Your code here
end

Need a hint?

Setting the log level to info reduces log noise while keeping important information.
