Installation

Clone the repository

git clone https://github.com/Grigore-George-Mihai/default_template_r8

---

Setup

1. Rename the Application

This will update the app name everywhere it appears (module name, titles, DB names, cable prefixes, Docker volumes, etc.).

bin/rails setup:rename_app

2. Create Environment Files

Copy environment template files into .env.development and .env.test.

bin/rails setup:copy_env

Then open each file and update values as needed:

• Database credentials (POSTGRES_USER, POSTGRES_PASSWORD)
• Any other environment-specific variables

3. Set Up the Database

bin/rails db:prepare   # Creates and migrates the database
bin/rails db:seed      # Loads seed data

4. Optional Integrations

• Devise — Adjust configuration in config/initializers/devise.rb if needed.
• Scout APM — Add your SCOUT_KEY value in .env.development (or the appropriate .env file) to enable. If left blank, ScoutAPM stays disabled.
• Rollbar — Add your ROLLBAR_ACCESS_TOKEN value in .env.development (or the appropriate .env file) to enable. If left blank, Rollbar stays disabled.
• PgHero - Add shared_preload_libraries = 'pg_stat_statements' to postgresql.conf and restart the database. if left blank, PgHero stays disabled.

✅ You’re now ready to start development!
