  app.conf.beat_schedule = {
      'send-sla-reminders': {
          'task': 'apps.complaints.tasks.send_sla_reminders',
          'schedule': crontab(minute='*/15'),  # Every 15 minutes
      },
      'check-overdue-complaints': {
          'task': 'apps.complaints.tasks.check_overdue_complaints',
          'schedule': crontab(minute='*/30'),  # Every 30 minutes
      },
  }
  

2. Email Notification Delivery

Model Architecture

Complaint Model (apps/complaints/models.py)

SLA-Related Fields:

# SLA Management
due_at = models.DateTimeField(null=True, blank=True, db_index=True)
is_overdue = models.BooleanField(default=False, db_index=True)

# Reminder Tracking
reminder_sent_at = models.DateTimeField(null=True, blank=True)
second_reminder_sent_at = models.DateTimeField(null=True, blank=True)

# Escalation Tracking
escalated_at = models.DateTimeField(null=True, blank=True)
escalation_level = models.IntegerField(default=0)
escalated_to = models.ForeignKey('accounts.User', related_name='escalated_complaints', ...)

# SLA Metadata
metadata = models.JSONField(default=dict, blank=True)

Key Methods:

• calculate_sla_due_date() - Calculates SLA deadline based on config
• check_overdue() - Updates overdue status and triggers escalation if needed
• send_sla_reminder() - Sends reminder notifications
• escalate() - Escalates complaint to next level

ComplaintSLAConfig Model

Purpose: Configure SLA deadlines and reminders per hospital/severity/priority

Key Fields:

hospital = models.ForeignKey(Hospital, ...)
severity = models.CharField(choices=SeverityChoices.choices)
priority = models.CharField(choices=PriorityChoices.choices)
sla_hours = models.IntegerField(help_text="SLA in hours")

# Reminder Configuration
reminder_hours_before = models.IntegerField(help_text="First reminder hours before deadline")
second_reminder_enabled = models.BooleanField(default=False)
second_reminder_hours_before = models.IntegerField(help_text="Second reminder hours before deadline")

# Email Options
thank_you_email_enabled = models.BooleanField(default=True)

EscalationRule Model

Purpose: Configure multi-level escalation rules

Key Fields:

hospital = models.ForeignKey(Hospital, ...)
escalation_level = models.IntegerField(unique=True)
name = models.CharField(max_length=200)

# Trigger Configuration
trigger_on_overdue = models.BooleanField(default=True)
trigger_hours_overdue = models.IntegerField(default=0, help_text="Hours overdue to trigger")

# Reminder-based Escalation
reminder_escalation_enabled = models.BooleanField(default=False)
reminder_escalation_hours = models.IntegerField(default=0, help_text="Hours after reminder to escalate")

# Target Configuration
escalate_to_role = models.CharField(choices=ROLE_CHOICES)
escalate_to_user = models.ForeignKey('accounts.User', ...)

Task Architecture (apps/complaints/tasks.py)

Celery Tasks

1. send_sla_reminders

Purpose: Send first and second reminders for complaints approaching deadline

Frequency: Every 15 minutes (recommended)

Logic:

1. Query open/in-progress complaints with due_at within reminder window
2. Check if reminder already sent
3. Send email notification (bilingual)
4. Update reminder_sent_at or second_reminder_sent_at
5. Create timeline update

2. check_overdue_complaints

Purpose: Check for overdue complaints and trigger escalation

Frequency: Every 30 minutes (recommended)

Logic:

1. Query complaints with due_at < now
2. Call check_overdue() on each
3. If overdue and not yet escalated, trigger escalation
4. Create timeline update

3. escalate_complaint_auto

Purpose: Automatically escalate complaint based on escalation rules

Logic:

1. Find matching escalation rule for current level
2. Check if trigger condition is met (overdue hours or reminder hours)
3. Assign to escalation target (user or role)
4. Update escalation_level, escalated_at, escalated_to
5. Create timeline update
6. Send notification to new assignee

4. escalate_after_reminder

Purpose: Escalate complaints that haven't been addressed after reminder

Frequency: Every hour (recommended)

Logic:

1. Query complaints with second_reminder_sent_at > X hours ago
2. Check for reminder escalation rules
3. Escalate if conditions met

Production Recommendations

1. Immediate Actions Required

A. Configure Email Settings

# Update .env file
EMAIL_BACKEND=django.core.mail.backends.smtp.EmailBackend
EMAIL_HOST=your-smtp-host
EMAIL_PORT=587
EMAIL_USE_TLS=True
EMAIL_HOST_USER=your-smtp-username
EMAIL_HOST_PASSWORD=your-smtp-password
DEFAULT_FROM_EMAIL=noreply@px360.sa

B. Start Celery Workers and Beat

# Terminal 1: Celery Worker
celery -A config.celery worker --loglevel=info

# Terminal 2: Celery Beat (scheduler)
celery -A config.celery beat --loglevel=info

C. Configure Celery Beat Schedule

# config/celery.py
app.conf.beat_schedule = {
    'send-sla-reminders-every-15-minutes': {
        'task': 'apps.complaints.tasks.send_sla_reminders',
        'schedule': crontab(minute='*/15'),
    },
    'check-overdue-complaints-every-30-minutes': {
        'task': 'apps.complaints.tasks.check_overdue_complaints',
        'schedule': crontab(minute='*/30'),
    },
    'escalate-after-reminder-every-hour': {
        'task': 'apps.complaints.tasks.escalate_after_reminder',
        'schedule': crontab(minute='0'),
    },
}

2. SLA Configuration Guidelines

Default SLA Recommendations

Severity	Priority	SLA Hours	First Reminder	Second Reminder
high	high	24	12h	3h
high	medium	48	24h	6h
medium	high	48	24h	6h
medium	medium	72	48h	12h
low	low	120	72h	24h

Escalation Rule Recommendations

Level	Name	Trigger	Hours	Target
1	First Escalation	Overdue	0h	Department Manager
2	Second Escalation	After Reminder	12h	Hospital Admin
3	Third Escalation	Overdue	24h	PX Admin

3. Monitoring and Alerts

Key Metrics to Monitor

1. SLA Compliance Rate

   • Percentage of complaints resolved within SLA
   • Track by hospital, department, severity, priority

2. Overdue Complaints

   • Number of overdue complaints
   • Average hours overdue
   • Time to resolution after overdue

3. Escalation Rate

   • Number of escalated complaints
   • Escalation level distribution
   • Time to resolution after escalation

4. Reminder Effectiveness

   • Complaints resolved after first reminder
   • Complaints resolved after second reminder
   • Complaints requiring escalation

Recommended Monitoring Queries

# SLA Compliance by Hospital
from django.db.models import Count, Case, When, IntegerField

Complaint.objects.values('hospital__name').annotate(
    total=Count('id'),
    on_time=Count(Case(
        When(resolved_at__lte=F('due_at'), then=1),
        output_field=IntegerField()
    )),
    overdue=Count(Case(
        When(is_overdue=True, then=1),
        output_field=IntegerField()
    ))
)

# Average Resolution Time
from django.db.models import Avg

Complaint.objects.filter(
    status=ComplaintStatus.CLOSED
).annotate(
    resolution_time=ExpressionWrapper(
        F('resolved_at') - F('created_at'),
        output_field=DurationField()
    )
).aggregate(avg_resolution=Avg('resolution_time'))

4. Best Practices

A. SLA Configuration

• Start with conservative SLA times (more forgiving)
• Monitor compliance rates for 2-4 weeks
• Adjust based on actual performance data
• Different SLAs for different hospitals if needed

B. Escalation Rules

• Configure clear escalation paths
• Ensure escalation targets have appropriate permissions
• Test escalation paths with sample complaints
• Document escalation procedures for staff

C. Notifications

• Use bilingual templates (English/Arabic)
• Include clear action items in emails
• Provide direct links to complaint details
• Test email delivery before production

D. Timeline Tracking

• All SLA-related events should create timeline updates
• Include metadata for audit trails
• Make timeline visible to all stakeholders
• Export timeline for compliance reporting

5. Testing Checklist

Pre-Production Testing

• Create test SLA configs for all hospitals
• Create test escalation rules
• Configure SMTP settings
• Start Celery worker and beat
• Create test complaints at different SLA levels
• Verify first reminders are sent
• Verify second reminders are sent
• Verify overdue detection works
• Verify escalation works correctly
• Verify timeline updates are created
• Verify emails are delivered
• Test escalation paths end-to-end

Post-Production Monitoring

• Monitor Celery task execution logs
• Monitor email delivery rates
• Monitor SLA compliance rates
• Monitor escalation effectiveness
• Review overdue complaints daily
• Adjust SLA times based on data

Troubleshooting

Common Issues

1. Reminders Not Being Sent

Symptoms: No reminder emails, reminder_sent_at is NULL

Causes:

• Celery Beat not running
• Email settings not configured
• SMTP server not reachable

Solutions:

# Check Celery Beat is running
ps aux | grep celery

# Check Celery Beat logs
tail -f logs/celery_beat.log

# Test email configuration
python manage.py shell
>>> from django.core.mail import send_mail
>>> send_mail('Test', 'Test message', 'from@example.com', ['to@example.com'])

2. Overdue Detection Not Working

Symptoms: is_overdue flag not updating, escalation not triggered

Causes:

• check_overdue_complaints task not running
• due_at field is NULL
• Timezone configuration issues

Solutions:

# Check Celery Beat schedule
celery -A config.celery inspect registered

# Manually trigger overdue check
python manage.py shell
>>> from apps.complaints.tasks import check_overdue_complaints
>>> check_overdue_complaints()

3. Escalation Not Working

Symptoms: Complaints not escalating, escalation_level not increasing

Causes:

• No escalation rules configured
• Escalation target users not found
• Permission issues

Solutions:

# Check escalation rules
from apps.complaints.models import EscalationRule
rules = EscalationRule.objects.filter(hospital=hospital, is_active=True)
print(rules)

# Check escalation target users
from apps.accounts.models import User
users = User.objects.filter(hospital=hospital, role='department_manager')
print(users)

# Manually trigger escalation
from apps.complaints.tasks import escalate_complaint_auto
result = escalate_complaint_auto.delay(str(complaint.id))
print(result.get())
