def selectwarehouse(request):
    z = Warehouse.objects.all()
    return render(request, 'packsapp/employee/selectwarehouse.html', {'z': z})

def warehouse_details(request):
    queryset = AllotmentDocket.objects.get(id=request.POST.get('object_id'))
    //Now to access the element in queryset write (queryset.'attribute name')
    return render(request, 'packsapp/employee/allotwarehousedetails.html', {'query': 
    queryset}

Check if this works

Try printing the queryset and see what is the output.
