I have created a model 'VehicleDetails' in which a user can fill the details of a vehicle and another model 'TripStatus' in which he can update the vehicle location. I wanted to get the latest location for which I did as in my below code. But when i running the server, it returns all the values not the latest value. I would appreciate helping me solve this or suggesting a new approach.
models.py:
class VehicleDetails(models.Model):
Vehicle_No = models.CharField(max_length=20)
class TripStatus(models.Model):
vehicledetails = models.ForeignKey(VehicleDetails, related_name='tripstatuss')
CHOICES = (('Yet to start', 'Yet to start'),('Trip starts', 'Trip starts'), ('Chennai','Chennai'), ('Vizag', 'Vizag'), ('Kolkata', 'Kolkata'))
Vehicle_Status = models.CharField(choices=CHOICES, default="Yet to start", max_length=20)
statustime = models.DateTimeField(auto_now=False, auto_now_add=True)
views:
def status(request):
tripstatus = TripStatus.objects.all().latest('statustime')
context = {
"tripstatus": tripstatus,
}
return render(request, 'loggedin_load/active_deals.html', context)
template:
{% for status in vehicledetails.tripstatuss.all %}
{{status.Vehicle_Status}}
{% endfor %}
Should just have to remove the .all():
tripstatus = TripStatus.objects.latest('statustime')
Or maybe:
tripstatus = TripStatus.order_by('-statustime').first()
