Python

from django.db import models
from django.utils import timezone

class Service(models.Model):
    name = models.CharField(max_length=255)
    description = models.TextField(blank=True, null=True)
    duration_minutes = models.IntegerField(default=30)

    def __str__(self):
        return self.name

class AppointmentSlot(models.Model):
    service = models.ForeignKey(Service, on_delete=models.CASCADE)
    start_time = models.DateTimeField()
    end_time = models.DateTimeField()
    is_available = models.BooleanField(default=True)

    def __str__(self):
        return f"{self.service.name} - {self.start_time.strftime('%Y-%m-%d %H:%M')}"

class Booking(models.Model):
    service = models.ForeignKey(Service, on_delete=models.CASCADE)
    appointment_slot = models.ForeignKey(AppointmentSlot, on_delete=models.CASCADE)
    customer_name = models.CharField(max_length=255)
    customer_email = models.EmailField()
    booking_date = models.DateTimeField(auto_now_add=True)

    class Meta:
        unique_together = ('appointment_slot',) # منع حجز نفس الموعد مرتين

    def __str__(self):
        return f"Booking for {self.customer_name} - {self.service.name} at {self.appointment_slot.start_time.strftime('%Y-%m-%d %H:%M')}"
