Ruby on Rails upgradation to 7.0.4

Upgrading to Rails 7.0.4 from Rails 6 can be a smooth process if done correctly. However, it is always a good idea to create a backup of your current codebase and database before starting the upgrade process. In this blog post, we will go through the steps to upgrade your Rails 6 application to Rails 7.0.4.

Step 1: Upgrade your Rails version

The first step is to update your Rails version to the latest stable version. Open your Gemfile and change the Rails version to 7.0.4:

gem 'rails', '~> 7.0.4'

Then, run `bundle install` to install the latest version of Rails and update your Gemfile.lock file.

Step 2: Update your dependencies

Next, you need to update your application's dependencies to their latest versions. To do this, run the following command:

bundle update

This will update all your dependencies, including Rails, to their latest versions.

Step 3: Check your application for deprecations

Rails 7.0.4 introduces a lot of changes, and some features that were previously deprecated are now removed. Run the following command to check for any deprecations:

rails app:update

This command will analyze your codebase and provide a list of any deprecations you need to fix. Be sure to carefully review the output and fix any issues as needed.

Step 4: Upgrade your Rails configuration

The Rails 7.0.4 configuration has changed significantly from Rails 6. Update your configuration files as follows:

config/application.rb:

# Replace the following line:
config.load_defaults 6.1

# With this line:
config.load_defaults 7.0

config/environments/development.rb, config/environments/production.rb, and config/environments/test.rb:

# Replace the following line:
config.action_mailer.raise_delivery_errors = false

# With this line:
config.action_mailer.raise_delivery_errors = true

config/initializers/filter_parameter_logging.rb:

# Replace the following line:
Rails.application.config.filter_parameters += [:password]

# With this line:
Rails.application.config.filter_parameters += [:password, :password_confirmation]

Step 5: Test your application

After upgrading your application, you should test your application thoroughly to ensure that everything works as expected. Run your tests and manual testing for your critical flows.

Step 6: Deploy to production

Once you have verified that your application works correctly in development, it is time to deploy to production. Before deploying, be sure to backup your production database and files.

Step 7: Monitor your application

After deploying your application to production, monitor your application closely for any issues or errors. Fix any issues as they arise, and continue to monitor your application to ensure that everything works as expected.

In conclusion, upgrading your Rails application to Rails 7.0.4 requires careful planning and attention to detail. By following these steps and testing your application thoroughly, you can successfully upgrade your application to the latest version of Rails.
