# Appointment Settings API

> **Prefix:** `/api/v1/appointment-settings`  
> **Permission:** All write endpoints require `AUTH` — must be the doctor owner or `ROLE_ADMIN`

Doctors configure their availability via three resources: **weekly schedule**, **date overrides**, and **holidays**.

---

## Weekly Schedule

Each doctor has **one** weekly schedule (upsert). The schedule is keyed by **day index** (0=Saturday ... 6=Friday), each day containing a `sessions` array.

### Day Index Convention

| Index | Day (EN) | Day (FA) |
|-------|----------|----------|
| `"0"` | Saturday | شنبه |
| `"1"` | Sunday | یکشنبه |
| `"2"` | Monday | دوشنبه |
| `"3"` | Tuesday | سه‌شنبه |
| `"4"` | Wednesday | چهارشنبه |
| `"5"` | Thursday | پنجشنبه |
| `"6"` | Friday | جمعه |

---

### POST `/api/v1/appointment-settings/weekly-schedule`

Create or update the weekly schedule for a doctor (upsert).

**Permission:** `AUTH` — must be the doctor owner or `ROLE_ADMIN`

> **الزام آدرس:** هر session با `active=true` باید `location_id` (آدرس مطب/کلینیک) داشته باشد. در غیر این صورت `422 ERR_VALIDATION_001` («برای هر شیفت فعال باید آدرس انتخاب شود»). این آدرس هنگام رزرو خودکار روی نوبت ذخیره می‌شود.

### Request Body (`application/json`)
```json

  }
}
```

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `doctor_uuid` | string (UUID) | ✅ | Doctor UUID |
| `schedule` | object | ✅ | Keys `"0"` through `"6"` (day indices) |
| `schedule.{n}.sessions` | array | ✅ | Array of session config objects |
| `meta` | object | ❌ | Online-booking settings (see below) |

**Online-booking `meta` object:**

```json
{
  "meta": {
    "online_booking_enabled": true,
    "booking_window_value": 2,
    "booking_window_unit": "month",
    "booking_mode": "service",
    "buffer_minutes": 5
  }
}
```

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `online_booking_enabled` | boolean | ❌ | `false` = no online booking; the public slot/month endpoints return no availability |
| `booking_window_value` | integer | ❌ | How far ahead patients may book (≥ 1) |
| `booking_window_unit` | string | ❌ | `"week"` or `"month"` |
| `booking_mode` | string | ❌ | `"slot"` (پیش‌فرض) = نوبت‌دهی اسلاتی با مدت ثابت (`duration_per_patient`). `"service"` = مدت هر نوبت از `duration_minutes` سرویسِ انتخاب‌شده؛ زمان‌ها با `GET /api/v1/appointment-service-slots` گرفته می‌شوند. مقدار نامعتبر نادیده گرفته می‌شود |
| `buffer_minutes` | integer | ❌ | فقط حالت سرویسی: فاصلهٔ بین نوبت‌ها (دقیقه، ≥ 0). در `slot_end` ذخیره نمی‌شود؛ فقط فاصلهٔ بین زمان‌های پیشنهادی |

> Defaults when `meta` is absent: `{ online_booking_enabled: true, booking_window_value: 1, booking_window_unit: "month", booking_mode: "slot", buffer_minutes: 0 }`. `meta` is stored inside the schedule `setting` JSON (no DB migration) and is **preserved** when only `schedule` is sent. `SlotCalculatorService` rejects any date in the past, beyond `today + value unit`, or when online booking is disabled — for the weekly schedule, date overrides, and `appointment-slots` alike.
>
> **اجبار حالت سرویسی:** اگر `booking_mode = service` ذخیره شود ولی پزشک هیچ سرویسِ «نمایش در نوبت‌دهی» (`bookable = true`) نداشته باشد، `POST`/`PATCH` برنامهٔ هفتگی با `422` (`ERR_VALIDATION_001`, field `booking_mode`) رد می‌شود.
>
> **غیرقابل‌تغییر پس از ثبت:** `booking_mode` فقط تا **اولین ثبت** قابل‌انتخاب است. پس از آنکه یک‌بار به‌صورت صریح ذخیره شد (در `setting.meta.booking_mode` نوشته شد)، هر `POST`/`PATCH` که آن را تغییر دهد با `422` («نوع نوبت‌دهی پس از ثبت قابل تغییر نیست»، field `booking_mode`) رد می‌شود. پاسخِ `toArray` فیلد boolean `booking_mode_locked` را برمی‌گرداند (`true` = قفل‌شده) تا پنل توگل را غیرفعال کند. رکوردهای قدیمی که هنوز mode صریح ندارند، `booking_mode_locked=false` و یک‌بار قابل‌انتخاب‌اند.

**Session Config Object:**

| Field | Type | Required | Description |
|-------|------|----------|-------------|
| `active` | boolean | ✅ | Whether this session is active |
| `location_id` | integer\|null | ❌ | Doctor address/location ID |
| `start_time` | string | ✅ | Session start `"HH:MM"` |
| `end_time` | string | ✅ | Session end `"HH:MM"` |
| `duration_per_patient` | integer | ✅ | Minutes per appointment slot |
| `has_rest` | boolean | ❌ | Whether to insert rest breaks |
| `rest_interval` | integer | ❌ | Work minutes before taking a rest break |
| `time_to_rest` | integer | ❌ | Duration of each rest break (minutes) |
| `patient_limit` | integer\|null | ❌ | Max patients per session (`null` = unlimited) |

> Multiple sessions per day are supported (e.g., morning + afternoon). Sessions are sorted by `start_time` and overlapping ones are skipped.

## Slot Calculation Logic (Reference)

The `SlotCalculatorService` calculates available slots in this priority order:

1. **Holiday** — if date falls in a holiday range → return empty (no slots)
2. **Date Override** — if a date override exists for this date:
   - `active: false` → return empty
   - `active: true` → use `custom_slots` sessions
3. **Weekly Schedule** — use the day's `sessions` array (only `active: true` sessions, sorted by `start_time`, overlapping sessions skipped)

**Slot output format:**
```json
[
  {
    "start": 1718438400,
    "end": 1718439600,
    "start_time": "09:00",
    "end_time": "09:20",
    "location_id": 1973
  }
]
```

## Available Locations

### `GET /api/v1/appointment-settings/available-locations/{doctorUuid}`

Returns all locations a doctor can assign as `location_id` in their schedule sessions. Includes both the doctor's personal addresses and the addresses of all clinics they belong to.
