How to perform grouping and ordering

I have a Ticket booking model

class Movie(models.Model):

   name = models.CharField(max_length=254, unique=True)

class Show(models.Model):

   day = models.ForeignKey(Day)

   time = models.TimeField(choices=CHOICE_TIME)

   movie = models.ForeignKey(Movie)

class MovieTicket(models.Model):

   show = models.ForeignKey(Show)

   user = models.ForeignKey(User)

   purchased_at = models.DateTimeField(default=timezone.now)

I would like to filter MovieTicket with its user field and group them according to its show field, and order them by the booked_at field. And respond back with json data using Django rest framework like this:

[

   {

       show: 4,

       movie: "Lion king",

       time: "07:00 pm",

       day: "23 Apr 2017",

       total_tickets = 2

   },

   {

       show: 7,

       movie: "Gone girl",

       time: "02:30 pm",

       day: "23 Apr 2017",

       total_tickets = 1

   }

]

I tried this way:

>>> MovieTicket.objects.filter(user=23).order_by('-booked_at').values('show').annotate(total_tickets=Count('show'))

<QuerySet [{'total_tickets': 1, 'show': 4}, {'total_tickets': 1, 'show': 4}, {'total_tickets': 1, 'show': 7}]>

As you can see its not grouping according to the show. Also how can I add other related fields (i.e., show__movie__name, show__day__date, show__time)?
