# IKEA Foundation - Week 2026 Project

This project is a Ruby on Rails application developed for the IKEA Foundation. It is a multi-lingual, interactive game/educational tool where players progress through various stages, making choices or facing "chance" events.

## Key Features

- **Multi-lingual Support:** Uses the `mobility` gem for translating content into numerous languages. Supported locales include: en, zh, hr, cs, da, nl, fi, fr, fr-CA, de, hu, it, ja, ko, nb, pl, pt, ro, sr, sk, sl, es, sv, uk.
- **Hierarchical Content Management:** A "Node" system (using `ancestry`) for managing pages, stages, and interactive elements.
- **Player Progression:** Tracks player progress, scores, and decisions across different stages in the `Player` model's `progress` JSONB field.
- **Interactive Game Flow:** Managed by `StagesController`, featuring:
  - **Flip:** Randomly determines if a stage is a "chance" or "choice" event.
  - **Reveal:** Displays the specific content for the flipped event.
  - **Pick:** For "chance", randomly samples an outcome; for "choice", records the player's selection.
  - **Result:** Shows the outcome (e.g., best, bad, good, game_over) based on the previous step.
- **Admin Interface:** A backend for managing nodes, assets (Active Storage), users, and translations.
- **Search:** `pg_search` integration for content discovery.

## Technical Stack

- **Framework:** Ruby on Rails 8.1.2
- **Language:** Ruby 3.4.9
- **Database:** PostgreSQL
- **Asset Pipeline:** Propshaft with Importmap-rails and Stimulus/Turbo.
- **Background Jobs:** Sidekiq with Redis.

## Core Models

- `Node`: The central content model. Templates are hierarchy-dependent:
  - **Root (Depth 0):** `start`
  - **Level 1:** `stage`
  - **Level 2:** `choice`, `chance`
  - **Level 3 (under choice/chance):** `best`, `bad`, `good`, `game_over`
- `Player`: Tracks session state, `progress`, `current_stage`, and `score`.
- `Asset` & `Attachment`: Handles media and its contextual content (body text, styling) associated with nodes.
- `User`: Admin authentication and roles.

## Project Structure

- `app/controllers/admin/`: Admin backend logic.
- `app/controllers/stages_controller.rb`: Main game loop (Flip -> Reveal -> Pick -> Result).
- `app/controllers/site_controller.rb`: Content delivery for standard pages.
- `app/models/concerns/`: Shared logic for ancestry, attachments, and tags.
- `config/locales/`: YAML translation files.
