Expecting JSON object instead of JSON Array

In my django application with database engine djongo, I'm trying to return a JSON response by retrieving from my database. But, I'm receiving JSON array instead of JSON object. Currently, there is only one record in my database. Please see the code below.

model.py

class bloodDonors(models.Model):
location=models.CharField(max_length=20)
name=models.CharField(max_length=20)
phone=models.IntegerField()
address=models.TextField()
bloodGroup=models.CharField(max_length=5)
type=models.CharField(max_length=20)
def __str__(self):
    return self.name

views.py

class bloodDonersView(viewsets.ModelViewSet):
    queryset = bloodDonors.objects.all()
    serializer_class = bloodDonorsSerializer

JSON Reponse:

[
    {
        "id": 3,
        "location": "Delhi",
        "name": "Tony",
        "phone": 888,
        "address": "South street",
        "bloodGroup": "B+",
        "type": "blood-donation"
    }
]

But, actually I needed the response as given below:

{
    "id": 3,
    "location": "Delhi",
    "name": "Tony",
    "phone": 888,
    "address": "South street",
    "bloodGroup": "B+",
    "type": "blood-donation"
}
