i need to send in response array of chats in my my chat view from chat model

Question

Following are my models:

class MediaUploads(models.Model):
    file = models.FileField(upload_to='embla/uploads/')
    caption = models.CharField(max_length=256, null=True, blank=True)
    owner = models.ForeignKey(User, related_name='embla_uploads',
                              on_delete=models.CASCADE, null=True, blank=True)
    created_at = models.DateTimeField(auto_now_add=True)

class Profile(models.Model):

...other unlreated keys,

photo = models.ForeignKey(MediaUploads,on_delete=models.DO_NOTHING,related_name='profile_photos',
                          null=True, blank=True) 

name = models.CharField(max_length=256)

...other unrelated keys,


class Message(models.Model):
    sender = models.ForeignKey(
        to=Profile, on_delete=models.CASCADE, related_name="sender")
    receiver = models.ForeignKey(
        to=Profile, on_delete=models.CASCADE, related_name="receiver")
    message = models.CharField(max_length=999)
    timestamp = models.DateTimeField(auto_now_add=True)
    is_read = models.BooleanField(default=False)

    def __str__(self):
        return self.message

    class Meta:
        ordering = ('timestamp',)

Following is my view:

class ChatView(APIView):
    searilzer_class = MessageSearlizer

    def get(self, request, *args, **kwargs):
        sender_id = self.request.user.profile.pk

        #  i need this chats here
        #  On client side i need to show the list of chats along with the names and pictures 
        #  of the people the user is engaged in chat. i have attached the picture of the 
        # client side view
        chats =

        return Response({"chats": chats})

I am Nodejs developer and due to insistence of client, doing my first project on django. chat would be array of objects. This array will have 3 keys. receiver name, receiver photo and receiver last message.
