Type Mismatch In Django Serializer For Request Parsing

I had created the following serializers for request parsing of JSON data. However, while performing the operation, I get an unexpected error. class A(serializers.ModelSerializer):

Solution 1:

class A(serializers.ModelSerializer):            
    class Meta:                                                
        model = CName                                  
        fields = ('id','contact','email')                      
        read_only_fields=('contact',)  

    def save(self, **kwargs):
        [obj.save(**kwargs) for obj in self]

Use custom save method while saving.
