Django Rest framework- getting total number of rows - django

Question

I would like to output a field that counts the number of Candidat in Candidat Model. I am currently using the following serializer:
class CountCSerializer(serializers.ModelSerializer):
user_count = serializers.SerializerMethodField()
class Meta:
model = Candidat
fields = ( 'user_count',)
def get_user_count(self, obj):
return Candidat.objects.count()
and the following api:
class CountCViewSet(ModelViewSet):
queryset = Candidat.objects.all()
serializer_class = CountCSerializer
urls.py:
router.register(r'CountC', CountCViewSet, base_name='users-count')
models.py:
class Candidat(models.Model):
name = models.CharField(max_length=50)
lastName = models.CharField(max_length=50)
email = models.CharField(max_length=50)
tel = models.CharField(max_length=50, default=0)
password = models.CharField(max_length=50)
civility = models.CharField(max_length=50)
birthDate = models.DateField(auto_now=False, auto_now_add=False)
gouvernorate = models.CharField(max_length=50)
def __str__(self):
return "Candidat: {}".format(self.name)
But im getting nothing!
Any help in the matter would be much appreciated.

I was looking for the same and noticed that ModelViewSet generates a count by default. You can see it by navigating to the endpoint in a browser or checking the response body in Postman.
Example:
{
"count": 10,
"next": null,
"previous": null,
"results": [
{
"id": 62,
"entity_name": "The company name",
"entity_website_url": "thecompany.com",
"entity_city": "Los Angeles",
"entity_state": "CA"
}
...
]
}
