case-insensitive pattern matching operator used by Supabase's `.ilike()` method. The problem is that you can't use `ilike` on UUID columns directly - it only works on text columns. In the fetchProductSuggestions function, I'm building an `or` filter that includes `id.ilike.%${searchTerm}%`, but `id` is a UUID column, not a text column. I have two options: - Remove the `id.ilike` from the search filters (simplest) - Cast the UUID to text in the query (more complex, requires using `.or()` with a raw SQL filter) Since the user wants to search by typing product names like "Apple", searching by UUID with ilike doesn't make much sense anyway. Users are more likely to type product names, brands, models, or SKUs - not UUIDs. The best solution is to remove the `id.ilike` filter from the search query entirely. If users want to search by exact UUID, they can scan the QR code or paste the full UUID. Let me read the current implementation and fix it.b9:T575,Based on the user's requirements, I need to: - Remove the "n ubicaciones diferentes" badge text (keep only the toast) - Make the product carousel a real slider (draggable) instead of using side buttons - Show only: title, last digits of ID, and location - Keep location at the bottom of the card for consistent UI - Fix the modal close behavior - it should just close, not refresh the entire website Looking at the current code: - Line 617-623: The badge showing "locationGroups.size ubicaciones diferentes" needs to be removed - Lines 625-665: The Carousel component is already there but needs to be made draggable - The carousel is using CarouselPrevious and CarouselNext buttons (lines 660-663) which should be removed for a pure slider - The Dialog component's onOpenChange might be causing the refresh issue For the carousel to be draggable like a slider, I need to: - Remove the CarouselPrevious and CarouselNext buttons - The embla-carousel (which powers shadcn's Carousel) already supports drag by default - Simplify the product card to show only title, last 5 digits of ID, and location at the bottom For the modal close issue, I need to check if there's any router.refresh() being called on close or if the Dialog is causing a page refresh. Looking at line 73, there's `onOpenChange={setOpen}` which should just update the state without refreshing.

# Inventory Management System

A comprehensive inventory management system built with Next.js, Supabase, and modern web technologies.

## Features

- **Product Management**: Track products with QR codes, categories, and specifications
- **Location Management**: Manage warehouses, stores, and storage locations with Mapbox integration
- **Ingresos (Draft Products)**: Create and manage incoming inventory
- **Categories**: Hierarchical category system with custom field schemas
- **Providers**: Manage suppliers and distributors
- **Sales**: Track sales, payments, and shipping
- **Transfer History**: Monitor product movements between locations

## Setup

### 1. Install Dependencies

\`\`\`bash
npm install
\`\`\`

### 2. Configure Environment Variables

You need to add the following environment variable to your Vercel project:

- `NEXT_PUBLIC_MAPBOX_TOKEN`: Your Mapbox API token for address autocomplete and maps

To get a Mapbox token:
1. Go to [https://account.mapbox.com/](https://account.mapbox.com/)
2. Sign up or log in
3. Go to "Access tokens"
4. Create a new token or use the default public token
5. Add it to your Vercel project environment variables

### 3. Run Database Setup

The database setup script is located at `scripts/setup_database.sql`. Run it from the v0 interface to create all necessary tables and seed data.

Then run the coordinate migration:
\`\`\`sql
-- Run scripts/add_location_coordinates.sql
\`\`\`

### 4. Start Development Server

\`\`\`bash
npm run dev
\`\`\`

## Technologies Used

- **Next.js 15**: React framework with App Router
- **Supabase**: PostgreSQL database with real-time capabilities
- **Mapbox GL JS**: Interactive maps and geocoding
- **shadcn/ui**: Beautiful UI components
- **React Flow**: Interactive node-based category visualization
- **QR Code Generation**: Product tracking with QR codes
- **TypeScript**: Type-safe development

## Key Features

### Location Management with Mapbox

- **Address Autocomplete**: Type an address and get suggestions from Mapbox with 500ms debounce
- **Coordinate Storage**: Automatically save latitude/longitude for each location
- **Interactive Maps**: View all locations on a map with custom markers
- **Share Addresses**: Share location addresses via Google Maps links
- **Statistics**: See product counts and draft counts per location

### Product Tracking

- QR code generation for each product
- Category-based custom fields
- Transfer history between locations
- Status tracking (draft, in_stock, sold, etc.)

### Ingresos (Incoming Inventory)

- Create draft products for incoming inventory
- Bulk operations
- Location assignment
- Provider tracking
