Update Seed File to Generate Notification Data and Implement Email Skipping

[hvillero]

Description

This PR updates the seed file to create a substantial amount of notification data for testing and development purposes. Additionally, it implements a mechanism to skip sending email notifications during the seeding process. This is achieved by using a global configuration controlled by an environment variable.

Key Changes

1. Seed File Updates:

   • The db/seeds.rb file has been modified to create 1000 notifications for each type (NewAircraftCreatedNotification, LogbookEntryUpdatedNotification, NewLogbookEntryCreatedNotification, UserSignUpNotification, and UserUpdateNotification).

2. Skip Email Notifications:

   • Introduced a global configuration in config/application.rb to control email notifications using the SEND_EMAIL_NOTIFICATIONS environment variable.
   • Updated notification classes to check the global configuration before sending email notifications.

Files Changed

• config/application.rb: Added config.send_email_notifications controlled by SEND_EMAIL_NOTIFICATIONS environment variable.
• config/environments/development.rb: Set SEND_EMAIL_NOTIFICATIONS to false to skip email notifications in development.
• notification classes: Updated to conditionally skip email notifications based on the global configuration.
• db/seeds.rb: Modified to create a large amount of notification data without sending emails.

Instructions

Set Environment Variable

For development and test environments, set the environment variable to false to skip email notifications:

export SEND_EMAIL_NOTIFICATIONS=false

How to Test

Development Environment:

• Run rails db:seed
