Description (last modified by Jerin Peter George)

I have a simple model as below, 

class Employee(models.Model):
    name = models.CharField(max_length=40, blank=False, null=False)
    salary = models.PositiveIntegerField()
    department = models.CharField(max_length=40, blank=False, null=False)
    hire_date = models.DateField(blank=False, null=False)
    age = models.IntegerField(blank=False, null=False)
    bonus = models.DecimalField(decimal_places=2, max_digits=15, null=True)

and I queried 

qs = Employee.objects.annotate(
    rank=Window(expression=Rank(), order_by=F("salary").desc()),
)

and then I have called the get() method to get the rank of a single specific object

qs.get(pk=pk).rank

Issue

The get(pk=pk).rank returning a constant value irrespective of the kwargs applied to the get() method
