How can I set default value in serializers?

Question

I have these serializers:

>---id = serializers.IntegerField()
>---name = serializers.CharField()
>---age = serializers.IntegerField()  

Now, I give the serializers this data:

{'id': 1, 'name': 'cc'}

I don't give a value for age. how can I set a default value to age in the serializers?

I want to get this, where the 12 is a default value:

{'id': 1, 'name': 'cc', 'age': 12}

Answer 1

age = serializers.IntegerField(default=12, initial=12)

initial to pre populate html form. See the docs
