# Testing Endpoint Prediksi di Postman

## 📋 Prerequisites

Sebelum test, pastikan:
1. ✅ Backend sudah running (`flask run`)
2. ✅ Model sudah tersimpan di database (`python scripts/save_model_to_db.py`)
3. ✅ User (mahasiswa) sudah terdaftar

---

## 🔐 Step 1: Login (Get JWT Token)

**Method**: POST  
**URL**: `http://localhost:5000/api/auth/login`  
**Body** (JSON):
```json
{
  "email": "mahasiswa@example.com",
  "password": "password123"
}
```

**Response** (Copy token untuk step berikutnya):
```json
{
  "access_token": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9...",
  "user": {
    "Id_User": 1,
    "email": "mahasiswa@example.com",
    "role": "mahasiswa",
    "mahasiswa": {
      "NIM": "220601001",
      "nama": "Budi Santoso",
      ...
    }
  }
}
```

---

## 👤 Step 2: Update Profile (Opsional - jika data belum lengkap)

**Method**: PUT  
**URL**: `http://localhost:5000/api/mahasiswa/profil`  
**Headers**:
```
Authorization: Bearer {ACCESS_TOKEN}
Content-Type: application/json
```

**Body** (JSON):
```json
{
  "angkatan": 2022,
  "gender": "laki-laki",
  "usia": 21,
  "freq_olahraga": "1-2 kali",
  "durasi_tidur": "6-7 Jam",
  "IPK": 3.5
}
```

**Response**:
```json
{
  "message": "Profil berhasil diperbarui.",
  "data": {
    "NIM": "220601001",
    "nama": "Budi Santoso",
    "angkatan": 2022,
    "gender": "laki-laki",
    "usia": 21,
    "freq_olahraga": "1-2 kali",
    "durasi_tidur": "6-7 Jam",
    "IPK": 3.5,
    ...
  }
}
```

---

## ✅ Step 3: Cek Profile Status

**Method**: GET  
**URL**: `http://localhost:5000/api/mahasiswa/profil/status`  
**Headers**:
```
Authorization: Bearer {ACCESS_TOKEN}
```

**Response**:
```json
{
  "is_complete": true,
  "missing_fields": []
}
```

Jika `is_complete: true`, profil sudah lengkap dan bisa submit kuesioner ✅

---

## 📝 Step 4: Submit Kuesioner (Prediksi)

**Method**: POST  
**URL**: `http://localhost:5000/api/mahasiswa/kuesioner`  
**Headers**:
```
Authorization: Bearer {ACCESS_TOKEN}
Content-Type: application/json
```

## 🔧 Setup di Postman

1. **Import Collection**:
   - Buka Postman → Import → Paste JSON di atas
   
2. **Set Environment Variable**:
   - Buka collection → Variables
   - Isi `access_token` setelah login

3. **Run Step by Step**:
   - ✅ Login → Copy token → Paste di variable
   - ✅ Update Profile (opsional)
   - ✅ Check Profile Status
   - ✅ Submit Kuesioner
   - ✅ Get Hasil
   - ✅ Get History

---

## ⚡ Expected Flow

```
Login (Token)
    ↓
Update Profile (optional - if needed)
    ↓
Check Profile Status (verify is_complete=true)
    ↓
Submit Kuesioner (S1-S40 + M1-M28)
    ↓
Backend:
    - Ambil data demografi dari profile mahasiswa
    - Validasi jawaban
    - Prediksi menggunakan pipeline
    - Simpan hasil ke database
    ↓
Response dengan:
    - tingkat_stres: "Rendah", "Sedang", "Tinggi"
    - tingkat_motivasi: "Rendah", "Sedang", "Tinggi"
    - saran: "Rekomendasi berdasarkan hasil"
```

---

## 🐛 Debugging

### Jika error "Profile tidak lengkap"
```
❌ error: "Profil Anda belum lengkap..."
```
**Solution**: 
1. GET `/api/mahasiswa/profil/status`
2. Lihat `missing_fields`
3. PUT `/api/mahasiswa/profil` dengan field yang missing

### Jika error "Validasi stres"
```
❌ error: "Validasi stres: Missing required question S1"
```
**Solution**: 
- Pastikan semua jawaban S1-S40 ada di JSON
- Value harus 1-4 (integer)

### Jika error "Model tidak tersedia"
```
❌ tingkat_stres: "Rendah" (fallback), tingkat_motivasi: "Sedang" (fallback)
```
**Solution**:
- Jalankan `python scripts/save_model_to_db.py`
- Cek database: `MLModel.query.filter_by(is_active=True).all()`
