🔧 Technical Implementation

Service Layer Enhancement

IPublicCollectionService Interface (Services/PublicCollectionService.cs)

/// <summary>
/// Gets a random public collection with full details including all artworks
/// </summary>
/// <returns>Random public collection details or null if no collections available</returns>
Task<PublicCollectionDetailsViewModel?> GetRandomPublicCollectionAsync();

PublicCollectionService Implementation

public async Task<PublicCollectionDetailsViewModel?> GetRandomPublicCollectionAsync()
{
    // Get count of public collections
    var totalCount = await _context.Collections
        .Where(c => c.IsPublic)
        .CountAsync();

    if (totalCount == 0)
    {
        return null;
    }

    // Generate random skip value
    var random = new Random();
    var skip = random.Next(0, totalCount);

    // Get a random collection with full details
    var collection = await _context.Collections
        .Include(c => c.User)
        .Include(c => c.Artworks.OrderBy(a => a.DisplayOrder))
        .Where(c => c.IsPublic)
        .OrderBy(c => c.Id) // Add deterministic ordering
        .Skip(skip)
        .FirstOrDefaultAsync();

    if (collection == null)
    {
        return null;
    }

    // Enrich the collection with full details
    return await EnrichCollectionDetailsAsync(collection);
}

Controller Layer Update

HomeController Modifications (Controllers/HomeController.cs)

public class HomeController : Controller
{
    private readonly IPublicCollectionService _publicCollectionService;
    // ... other dependencies

    public HomeController(IPublicCollectionService publicCollectionService, /* other params */)
    {
        _publicCollectionService = publicCollectionService;
        // ... other assignments
    }

    public async Task<IActionResult> Index()
    {
        _logger.LogInformation("Home page requested at {RequestTime}", DateTime.Now);

        try
        {
            // Try to get a random public collection
            var randomCollection = await _publicCollectionService.GetRandomPublicCollectionAsync();
            
            if (randomCollection != null)
            {
                // Increment view count for the showcased collection
                await _publicCollectionService.IncrementViewCountAsync(randomCollection.Id);
                return View(randomCollection);
            }
        }
        catch (Exception ex)
        {
            _logger.LogError(ex, "Error loading random collection for home page");
        }

        // Fallback to featured artworks if no collections available
        var featuredArtworks = await _artWorkService.GetFeaturedArtworksAsync();
        return View("IndexFallback", featuredArtworks);
    }
}
