If you want the records of the current User,

add a relationship attribute pointing the appointments model to the Users model so as to know who is the patient being treated... something like this,

Models.py:

#import for User model
from django.contrib.auth.models import User

class Appointment(models.Model):
    sno= models.AutoField(primary_key=True)
    doctor_name= models.CharField(max_length=255)
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    specialization= models.CharField(max_length=23)
    fee=models.CharField(max_length=20)
    #email= models.CharField(max_length=100)
    #time= models.TextField()
    #timeStamp=models.DateTimeField(auto_now_add=True, blank=True)

views.py

def appointmentInfo(request):

    appts= Appointment.objects.get(user__id = request.user.id)

    return render(request,'home/view_appointment.html',{'appoints':appts})
