# Electoral Roll PDF Import - Phase 1 Testing Guide

## ✅ Phase 1 Completed: Booth and Street Extraction

### What's Been Implemented:

#### 1. **Booth Extraction**
- Extracts booth number from "Part No. : 10" in page headers
- Extracts booth details from "3. Polling station details" section
- Pattern: `10 - Dr. B.R. Ambedkar Govt. Middle School (Western side-North)`
- Automatically saves/updates booth in database:
  - `booth_number`: 10
  - `booth_address`: Dr. B.R. Ambedkar Govt. Middle School (Western side-North)

#### 2. **Street Extraction**
- Extracts street list from "2. Details of part and polling area" section
- Detects patterns containing: Nagar, Street, Road, Cross, Lane
- Automatically saves streets and links them to the booth
- Each street is associated with its booth via `booth_id`

#### 3. **Statistics Tracking**
- `booths_processed`: Number of unique booths found
- `streets_processed`: Number of unique streets found
- Detailed logging for debugging

### Database Changes:

**Street Model** (`app/Models/Street.php`):
- Added `booth_id` to fillable fields
- Added `booth()` relationship

## 🧪 How to Test

### Step 1: Upload PDF via Postman

```http
POST http://localhost:8000/api/pdf-import/upload
Content-Type: multipart/form-data

Body (form-data):
- pdf_file: [Select your Electoral Roll PDF]
- process_immediately: true
- uploaded_by: 1
```

### Step 2: Check the Response

```json
{
  "status": "success",
  "message": "PDF processed successfully",
  "data": {
    "import_log": {
      "id": 1,
      "status": "completed",
      "total_voters": 0,
      "imported_voters": 0,
      "failed_voters": 0,
      "import_summary": {
        "total_pages": 5,
        "booths_processed": 1,
        "streets_processed": 15
      }
    }
  }
}
```

### Step 3: Verify Database

**Check Booths:**
```sql
SELECT * FROM booths ORDER BY id DESC LIMIT 5;
```

**Check Streets:**
```sql
SELECT s.*, b.booth_number 
FROM streets s 
LEFT JOIN booths b ON s.booth_id = b.id 
ORDER BY s.id DESC LIMIT 10;
```

### Step 4: Check Logs

```bash
tail -f storage/logs/laravel.log
```

Look for:
- "Found Part No (Booth): 10"
- "Saved Booth"
- "Saved Street"
- "PDF extraction completed"

## ❌ Phase 2: NOT Yet Implemented

- Voter data extraction from page 4 onwards
- Voter information parsing (Serial No, Voter ID, Name, etc.)
- Voter database insertion

---

## 🎯 Next Steps

1. **Test Phase 1**: Upload your Electoral Roll PDF
2. **Verify Data**: Check booths and streets tables
3. **Review Logs**: Ensure extraction is working correctly
4. **Phase 2**: Once verified, implement voter extraction

---

## 📋 PDF Format Expected

**Page 1-3**: Metadata, booth details, street lists
**Page 4+**: Voter listings with:
- Serial Number in box (e.g., 1, 2, 3)
- Voter ID (e.g., BKZ7525959, UEB0199380)
- Name (e.g., THIRUNAVUKKARASU, Kaliyaperumal)
- Father/Husband Name
- House Number
- Age
- Gender (Male/Female)

---

## 🔧 Troubleshooting

**Issue**: Booth not extracted
- Check if "Part No." appears in PDF header
- Verify booth details follow pattern: `number - address`

**Issue**: Streets not extracted
- Verify "2. Details of part and polling area" section exists
- Check if street names contain: Nagar, Street, Road, Cross, Lane

**Issue**: Database errors
- Run: `php artisan migrate`
- Check `booth_id` column exists in `streets` table
