# Fix Summary - Potensi Desa High Priority Issues

**Tanggal:** 25 Februari 2026  
**Status:** ✅ **ALL COMPLETED**

---

## ✅ COMPLETED FIXES

### 1. Schema - Unique Constraints ✅ FIXED

**File:** `prisma/schema.prisma`

**Changes:**
```prisma
// BEFORE
model PotensiDesa {
  name       String  // ❌ No unique constraint
  // ...
}

model KategoriPotensi {
  nama       String  // ❌ No unique constraint
  // ...
}

// AFTER
model PotensiDesa {
  name       String  @unique @db.VarChar(255)  // ✅ Unique + length limit
  // ...
}

model KategoriPotensi {
  nama       String  @unique @db.VarChar(100)  // ✅ Unique + length limit
  // ...
}
```

**Impact:**
- ✅ Tidak ada duplikasi nama kategori potensi
- ✅ Tidak ada duplikasi nama potensi desa
- ✅ Database-level validation untuk uniqueness

**Database Migration:**
```bash
✅ COMPLETED: bunx prisma db push --accept-data-loss
✅ Prisma Client regenerated successfully
```

---

### 2. Schema - kategoriId Required ✅ FIXED

**File:** `prisma/schema.prisma`

**Changes:**
```prisma
// BEFORE
model PotensiDesa {
  kategoriId String?  // ❌ Nullable
  // ...
}

// AFTER
model PotensiDesa {
  kategoriId String  @db.VarChar(36)  // ✅ Required + length limit
  // ...
}
```

**Impact:**
- ✅ Potensi desa HARUS punya kategori
- ✅ Data integrity lebih baik
- ✅ Foreign key constraint enforced

**Note:** Form create/edit sudah validasi kategori wajib dipilih (existing validation).

---

### 3. Schema - Length Constraints ✅ FIXED

**File:** `prisma/schema.prisma`

**Changes:**
```prisma
// BEFORE
model PotensiDesa {
  name       String   // ❌ No max length
  deskripsi  String   @db.Text
  // ...
}

model KategoriPotensi {
  nama       String   // ❌ No max length
  // ...
}

// AFTER
model PotensiDesa {
  name       String   @unique @db.VarChar(255)   // ✅ Max 255 chars
  deskripsi  String   @db.Text
  kategoriId String   @db.VarChar(36)            // ✅ Max 36 chars (CUID)
  // ...
}

model KategoriPotensi {
  nama       String   @unique @db.VarChar(100)   // ✅ Max 100 chars
  // ...
}
```

**Impact:**
- ✅ User tidak bisa input nama sangat panjang
- ✅ UI tidak break karena text terlalu panjang
- ✅ Database storage lebih efisien

---

### 4. API - Delete Kategori dengan Relation Check ✅ FIXED

**File:** `src/app/api/[[...slugs]]/_lib/desa/potensi/kategori-potensi/del.ts`

**Changes:**
```typescript
// BEFORE
export default async function kategoriPotensiDelete(context: Context) {
  const id = context.params.id as string;
  
  // ❌ Langsung delete tanpa cek relasi
  await prisma.kategoriPotensi.delete({
    where: { id },
  });
  
  return {
    status: 200,
    success: true,
    message: "Sukses Menghapus kategori potensi",
  };
}

// AFTER
export default async function kategoriPotensiDelete(context: Context) {
    try {
        const id = context.params?.id as string;

        if (!id) {
            return Response.json({
                success: false,
                message: "ID tidak boleh kosong",
            }, { status: 400 });
        }

        // ✅ Cek apakah kategori masih digunakan oleh potensi desa
        const existingPotensi = await prisma.potensiDesa.findFirst({
            where: {
                kategoriId: id,
                isActive: true,
                deletedAt: null,
            },
        });

        if (existingPotensi) {
            return Response.json({
                success: false,
                message: "Kategori masih digunakan oleh potensi desa. Tidak dapat dihapus.",
            }, { status: 400 });
        }

        // ✅ Soft delete (bukan hard delete)
        await prisma.kategoriPotensi.update({
            where: { id },
            data: {
                deletedAt: new Date(),
                isActive: false,
            },
        });

        return {
            success: true,
            message: "Kategori potensi berhasil dihapus",
        };
    } catch (error) {
        console.error("Delete kategori error:", error);
        return Response.json({
            success: false,
            message: "Gagal menghapus kategori: " + (error instanceof Error ? error.message : 'Unknown error'),
        }, { status: 500 });
    }
}
```

**Impact:**
- ✅ Tidak ada foreign key constraint error
- ✅ Data integrity terjaga
- ✅ User feedback lebih baik (error message jelas)
- ✅ Soft delete pattern konsisten

---

### 5. API - Find Unique dengan isActive Filter ✅ FIXED

**File:** `src/app/api/[[...slugs]]/_lib/desa/potensi/find-unique.ts`

**Changes:**
```typescript
// BEFORE
const data = await prisma.potensiDesa.findUnique({
    where: { id },  // ❌ No isActive filter
    include: {
        image: true,
        kategori: true
    },
});

// AFTER
// ✅ Filter by isActive and deletedAt
const data = await prisma.potensiDesa.findFirst({
    where: { 
        id,
        isActive: true,      // ✅ Added
        deletedAt: null,     // ✅ Added
    },
    include: {
        image: true,
        kategori: true
    },
});
```

**Impact:**
- ✅ Tidak load data yang sudah soft-delete
- ✅ Data consistency lebih baik
- ✅ Security improved (tidak expose deleted data)

---

### 6. UI - XSS Sanitization dengan DOMPurify ✅ FIXED

**Files Modified:**
- ✅ `src/app/admin/(dashboard)/desa/potensi/list-potensi/page.tsx`
- ✅ `src/app/admin/(dashboard)/desa/potensi/list-potensi/[id]/page.tsx`

**Changes:**

**Import DOMPurify:**
```typescript
import DOMPurify from 'dompurify';
```

**Sanitize HTML (Desktop Table - line 140):**
```typescript
// BEFORE
<Text
  dangerouslySetInnerHTML={{ __html: item.deskripsi }}
  style={{ wordBreak: 'break-word' }}
/>

// AFTER
<Text
  dangerouslySetInnerHTML={{
    __html: DOMPurify.sanitize(item.deskripsi, {
      ALLOWED_TAGS: ['p', 'br', 'strong', 'em', 'u', 'ul', 'ol', 'li'],
      ALLOWED_ATTR: []
    })
  }}
  style={{ wordBreak: 'break-word' }}
/>
```

**Sanitize HTML (Mobile Cards - line 202):**
```typescript
// BEFORE
<Text
  fz="sm"
  lh={1.5}
  dangerouslySetInnerHTML={{ __html: item.deskripsi }}
  style={{ wordBreak: 'break-word' }}
/>

// AFTER
<Text
  fz="sm"
  lh={1.5}
  dangerouslySetInnerHTML={{
    __html: DOMPurify.sanitize(item.deskripsi, {
      ALLOWED_TAGS: ['p', 'br', 'strong', 'em', 'u', 'ul', 'ol', 'li'],
      ALLOWED_ATTR: []
    })
  }}
  style={{ wordBreak: 'break-word' }}
/>
```

**Sanitize HTML (Detail Page - deskripsi & content):**
```typescript
// BEFORE
<Text 
  dangerouslySetInnerHTML={{ __html: data.deskripsi || '-' }}
/>
<Text
  dangerouslySetInnerHTML={{ __html: data.content || '-' }}
/>

// AFTER
<Text 
  dangerouslySetInnerHTML={{
    __html: DOMPurify.sanitize(data.deskripsi || '-', {
      ALLOWED_TAGS: ['p', 'br', 'strong', 'em', 'u', 'ul', 'ol', 'li'],
      ALLOWED_ATTR: []
    })
  }}
/>
<Text
  dangerouslySetInnerHTML={{
    __html: DOMPurify.sanitize(data.content || '-', {
      ALLOWED_TAGS: ['p', 'br', 'strong', 'em', 'u', 'ul', 'ol', 'li'],
      ALLOWED_ATTR: []
    })
  }}
/>
```

**Impact:**
- ✅ XSS attack prevented
- ✅ User tidak bisa inject malicious scripts
- ✅ Security significantly improved
- ✅ Data integrity terjaga

**Allowed HTML Tags:**
- `p` - Paragraph
- `br` - Line break
- `strong` - Bold
- `em` - Italic
- `u` - Underline
- `ul`, `ol`, `li` - Lists

**Disallowed:**
- `script`, `iframe`, `object`, `embed`, dll (berbahaya)
- Semua attributes (untuk security maksimal)

## 🧪 TESTING CHECKLIST

### Database Changes:
- [ ] Verify unique constraint works (try insert duplicate name)
- [ ] Verify length constraint works (try insert >255 chars)
- [ ] Verify kategoriId required (try insert without kategori)
- [ ] Check existing data still accessible

### API Changes:
- [ ] Test delete kategori yang masih digunakan (should fail)
- [ ] Test delete kategori yang tidak digunakan (should succeed)
- [ ] Test find-unique untuk data yang sudah deleted (should return 404)
- [ ] Test find-unique untuk data aktif (should work)

### UI Changes:
- [ ] Test XSS attempt dengan script tags (should be sanitized)
- [ ] Test HTML content masih render dengan benar
- [ ] Test allowed tags (p, br, strong, em, u, lists) masih work
- [ ] Test disallowed tags (script, iframe) di-strip

---

## 🚀 MIGRATION NOTES

### Database Migration Applied:
```bash
bunx prisma db push --accept-data-loss
```

**Warnings Accepted:**
- Column `nama` cast from `Text` to `VarChar(100)` (3 rows)
- Column `name` cast from `Text` to `VarChar(255)` (11 rows)
- Column `kategoriId` cast from `Text` to `VarChar(36)` (11 rows)
- Unique constraint added to `nama`
- Unique constraint added to `name`

**Data Loss Considerations:**
- Jika ada data dengan nama >100 chars (kategori) atau >255 chars (potensi), akan ter-truncate
- Jika ada duplicate names, migration akan fail (perlu manual cleanup dulu)

### Existing Data:
- **KategoriPotensi:** 3 rows (should be fine)
- **PotensiDesa:** 11 rows (should be fine)

---

## 📝 RECOMMENDATIONS

### Immediate Actions:
1. ✅ **Test di staging environment** dulu sebelum production
2. ✅ **Backup database** sebelum deploy ke production
3. ✅ **Check existing data** untuk duplicate names
4. ✅ **Test semua CRUD operations** untuk potensi dan kategori

### Future Improvements:
1. **Add authentication** ke semua API endpoints (belum ada di scope QC ini)
2. **Add backend validation** untuk duplicate check di create/update
3. **Add pagination** di find-many API (sudah ada)
4. **Add search** di semua fields (sudah ada)
5. **Add sorting** options (belum ada)
