Feature: Add AI-Powered Cinematic Assistant with Smart Recommendations and Contextual Insights

[Copilot]

Overview

This PR introduces an AI-driven cinematic assistant that transforms MovieVerse from a static database into a proactive, personalized cinematic companion. The assistant provides intelligent movie recommendations, contextual trivia, rewatch reminders, and curated weekly watchlists.

Motivation

Currently, MovieVerse offers search, curated lists, and watchlists, but these features are largely reactive—users query, and the system responds. This implementation adds an agentic AI layer that makes the experience proactive and adaptive, helping users discover what to watch based on mood, time available, viewing history, and learned preferences.

Implementation

Backend (Django)

New AI Agent Service (movieverse/ai_agent.py)

• CinematicAssistant class with intelligent recommendation algorithms
• User preference learning from viewing history and ratings
• Smart filtering by runtime, mood/genre, and previously watched movies
• Contextual reasoning generation for each recommendation

4 New REST API Endpoints (movieverse/views.py & movieverse/urls.py)

1. GET /api/agent/what-to-watch/ - Personalized movie suggestions based on time available, mood, and user history
2. GET /api/agent/trivia/ - Cinema facts, movie-specific trivia, and "On This Day" historical releases
3. GET /api/agent/rewatch-reminder/ - Smart suggestions for rewatching highly-rated movies after 6+ months
4. GET /api/agent/weekly-watchlist/ - Themed weekly collections (e.g., "Mind-Bending Thrillers", "Time Travel Adventures")

Comprehensive Test Suite (movieverse/tests.py)

• Added AIAgentTests class with full endpoint coverage

Key Features

1. Smart Recommendations

const assistant = new MovieVerseAssistant();
const recommendations = await assistant.getWhatToWatch({
  timeAvailable: 120,  // 2 hours
  mood: 'action',
  limit: 5
});
// Returns: personalized movies with contextual reasoning
// e.g., "Highly rated (8.5/10) • Perfect for your 120-minute window • Matches your action mood"

2. Contextual Trivia

• General cinema history facts
• Movie-specific information (runtime, ratings, release dates)
• "On This Day" feature showing movies released on the current date in history
• Easy integration into movie detail pages

3. Rewatch Reminders

• Analyzes user's highly-rated movies (4+ stars)
• Suggests rewatches after 6+ months
• Personalized reasoning (e.g., "You loved this 8 months ago. Time for a rewatch?")

4. Weekly Watchlists

• Themed collections: "Time Travel Adventures", "Classic Noir", "Feel-Good Comedies", etc.
• Curated high-quality movies (7.0+ rating)
• 7 movies per week for daily viewing

Technical Highlights

Recommendation Algorithm

1. Filter by user constraints (time, mood, already-watched movies)
2. Score based on vote average and user preferences
3. Boost movies matching user's top 3 favorite genres (learned from history)
4. Rank and return top N with contextual reasoning
5. Fallback to highly-rated movies when filters return no results

Multi-Database Integration

• MongoDB: Movie metadata, genres, cast/crew
• MySQL: User reviews and ratings
• PostgreSQL: User profiles and preferences
• Seamless cross-database queries using Django's multi-DB support

<issue_title>Feature: Agentic AI-Powered Cinematic Assistant</issue_title>
<issue_description>### Summary

Introduce an AI-driven cinematic assistant within MovieVerse that goes beyond static recommendations. The assistant would act as a personal movie guide, capable of dynamically adapting to user preferences, habits, and context — helping users decide what to watch, when to watch, and how to engage with cinema more meaningfully.

---

Motivation

Currently, MovieVerse provides search, curated lists, watchlists, and AI-powered recommendations. While powerful, these features are largely reactive: users query, and the system responds.

An agentic AI layer would make the experience proactive and adaptive:

• Suggest watchlists based on mood, time available, or trends.
• Notify users of hidden gems they might otherwise miss.
• Re-engage users by highlighting unfinished movies, sequels, or related films.
• Offer cinema history insights (“On this day in 1995, Se7en premiered!”).

This transforms MovieVerse from a database of movies into a personalized cinematic companion.

---

Proposed Solution

Backend Enhancements

• Add an AI Agent Service layered over existing Django/ML pipelines.

• New endpoints (example):

  • /api/agent/what-to-watch → Suggests films based on time, mood, and history.
  • /api/agent/trivia → Generates contextual facts about films.
  • /api/agent/rewatch-reminder → Suggests continuing unfinished series or trilogies.

Frontend Enhancements

• Add a “MovieVerse Assistant” panel on the dashboard.
• Inline suggestions while browsing (e.g., “Because you liked Inception, here’s 3 smart thrillers”).
• Chatbot-like interaction with MovieBot (but powered by agentic reasoning).

Use timezone.now() instead of datetime.now() for timezone-aware datetime operations in Django. This ensures consistency with Django's timezone handling and prevents issues with naive vs aware datetime comparisons.

[Copilot]

The module is exported for CommonJS environments, but the HTML file imports it as an ES module using import. This creates an incompatibility. Either export using ES6 export default MovieVerseAssistant; or change the HTML import to use a script tag with appropriate module bundling.

Suggested change

	if (typeof module !== 'undefined' && module.exports) {
	module.exports = MovieVerseAssistant;
	}
	export default MovieVerseAssistant;

[Copilot]

Similar to ai-assistant.js, this uses CommonJS exports but the module may be imported as ES6. Consider using ES6 export syntax (export { addMovieTrivia, addOnThisDayTrivia, initializeMovieTrivia }) to match modern JavaScript module standards and ensure compatibility.

Suggested change

	if (typeof module !== 'undefined' && module.exports) {
	module.exports = {
	addMovieTrivia,
	addOnThisDayTrivia,
	initializeMovieTrivia
	};
	}
	export { addMovieTrivia, addOnThisDayTrivia, initializeMovieTrivia };
