📋 Implementation Details

Signal Handlers (apps/complaints/signals.py)

# Called after complaint is created
post_save.connect(
    send_complaint_creation_sms,
    sender=Complaint,
    dispatch_uid='complaint_creation_sms'
)

# Called after complaint status changes
post_save.connect(
    send_complaint_status_change_sms,
    sender=Complaint,
    dispatch_uid='complaint_status_change_sms'
)

Model Changes (apps/complaints/models.py)

class Complaint(TenantModel):
    # ... existing fields ...
    
    def get_tracking_url(self):
        """Get the public tracking URL for this complaint"""
        return f"/complaints/track/{self.reference_number}/"
    
    def save(self, *args, **kwargs):
        # Track status changes for SMS notifications
        if self.pk:
            old_instance = Complaint.objects.get(pk=self.pk)
            self._status_was = old_instance.status
        super().save(*args, **kwargs)

SMS Message Templates

Messages are structured as dictionaries with language keys:

STATUS_CHANGE_MESSAGES = {
    'resolved': {
        'en': "Your complaint {ref} has been resolved. Summary: {resolution}",
        'ar': "تم حل شكواكم {ref}. الملخص: {resolution}"
    },
    'closed': {
        'en': "Your complaint {ref} is now closed. Thank you.",
        'ar': "تم إغلاق شكواكم {ref}. شكراً لتعليقاتكم."
    }
}
