# TalimBot - سیستم گروه‌بندی هوشمند دانش‌آموزان

A full-stack intelligent student grouping system using AI-powered analysis with FastAPI backend and GitHub Pages frontend.

## 🎯 Overview

TalimBot groups 30 real students based on MBTI personality types, learning styles, math grades, and peer preferences using AI (GPT-4o-mini via OpenRouter). Teachers control when students can view their group assignments.

### Real Student Data
- **30 Students** from class 1061 (دهم تجربی)
- **Persian Names**: Full Persian names from actual class roster
- **National Code Authentication**: Students login with their national ID
- **Math Grades**: Real grades from student records

---

## 🚀 Quick Start (Local Development)

### Prerequisites
- Python 3.8+ installed
- Modern web browser
- Internet connection (for AI grouping)

### Step 1: Start Backend (30 seconds)

```powershell
# Navigate to backend folder
cd backend

# Install dependencies (first time only)
pip install -r requirements.txt

# Start the server
python main.py
```

**Server runs on:** `http://localhost:8000`

**Keep this terminal running!**

### Step 2: Open Frontend (10 seconds)

**Option A - Direct Open (Easiest):**
- Double-click `index.html` in File Explorer

**Option B - Local Server (Recommended):**
```powershell
# In a NEW terminal window
python -m http.server 3000
```
Then visit: `http://localhost:3000`

## 👥 Login Credentials

### Students (30 students available)
Login with:
- **Student Number:** S001, S002, ..., S030
- **National Code:** Each student's 10-digit national ID

**Example:**
- Student Number: `S001`
- National Code: `929986644`
- Name: آدینه پور - یاسمن

### Teacher

## 🌐 Deployment to GitHub Pages

### Part 1: Deploy Frontend to GitHub Pages

1. **Create GitHub Repository**
   ```bash
   # Initialize git (if not already done)
   git init
   git add .
   git commit -m "Initial commit with real student data"
   
   # Create repo on GitHub and push
   git remote add origin https://github.com/talimbot/talimbot.git
   git branch -M main
   git push -u origin main
   ```

2. **Enable GitHub Pages**
   - Go to repository Settings → Pages
   - Source: Deploy from branch `main`
   - Folder: `/ (root)`
   - Click Save

3. **Your site will be live at:**
   `https://talimbot.github.io/talimbot/`

### Part 2: Deploy Backend to Render.com (Free)

1. **Create Render Account**
   - Visit [render.com](https://render.com)
   - Sign up with GitHub

2. **Create New Web Service**
   - Click "New +" → "Web Service"
   - Connect your GitHub repository
   - Settings:
     - **Name:** `talimbot-backend`
     - **Environment:** `Python 3`
     - **Build Command:** `pip install -r backend/requirements.txt`
     - **Start Command:** `cd backend && uvicorn main:app --host 0.0.0.0 --port $PORT`
     - **Plan:** Free

3. **Add Environment Variable**
   - In Render dashboard → Environment
   - Add: `OPENROUTER_API_KEY` = `your-api-key`
   - Optionally: `TEACHER_PASSWORD` = `your-password`

4. **Get Your Backend URL**
   - Copy the URL (e.g., `https://talimbot-backend.onrender.com`)

### Part 3: Update Frontend to Use Deployed Backend

Update `API_BASE_URL` in BOTH files:
- `assets/js/data.js`
- `assets/js/grouping.js`

```javascript
// Change from:
const API_BASE_URL = 'http://localhost:8000/api';

// To:
const API_BASE_URL = 'https://talimbot-backend.onrender.com/api';
```

Commit and push changes:
```bash
git add .
git commit -m "Update API URL for production"
git push
```

GitHub Pages will auto-deploy in ~1 minute.

---

## 🔧 Configuration

### API Key (OpenRouter)
Located in `backend/grouping_logic.py`:
```python
OPENROUTER_API_KEY = 'sk-or-v1-...'
```

### Teacher Password
Located in `backend/main.py` (SystemData model):
```python
teacherPassword: str = "teacher123"
```

Change as needed for security.

### Student Data
Students are initialized in `backend/main.py` in the `load_data()` function.
All 30 real students with Persian names and national codes are pre-loaded.

## 🐛 Troubleshooting

### "Failed to fetch" errors
**Problem:** Backend not running or wrong URL
**Solution:**
1. Check backend is running: Visit `http://localhost:8000`
2. Should see: `{"message":"TalimBot API is running"}`
3. Check `API_BASE_URL` in JS files matches backend

### Students can't login
**Problem:** Wrong national code
**Solution:**
- National code must be exactly 10 digits
- Must match the code in backend database
- Check `backend/main.py` for correct codes

### Students can't see groups
**Problem:** Teacher hasn't enabled visibility
**Solution:**
- Teacher must click "Show Results to Students"
- Button appears after grouping is complete

### Grouping fails
**Problem:** API error or no internet
**Solution:**
1. Check internet connection
2. Verify OpenRouter API key is valid
3. Check backend logs for errors
4. System has fallback random grouping if AI fails

## 🔐 Security Notes

### Current (Demo/Development):
- ✅ Simple password authentication
- ✅ CORS allows all origins
- ✅ National codes as passwords

### Recommended for Production:
- 🔒 Use environment variables for secrets
- 🔒 Implement JWT token authentication
- 🔒 Enable HTTPS only
- 🔒 Add rate limiting
- 🔒 Use PostgreSQL instead of JSON
- 🔒 Hash national codes
- 🔒 Implement proper session management
