Django Rest Framework- How to send data as strings

Question

I want to send all the data in a response as string, like in database id is stored as integers but I want to send it as string in response. eg: I have the response as

{
"categories": [
    {
        "id": 1,
        "category": "xya",
        "quantity": 25
    }
  ]
}

I want it to be as:

{
"categories": [
    {
        "id": "1",
        "category": "xya",
        "quantity": "25"
    }
  ]
}

I am using ModelSerializer to send all the fields.

Another option is to convert int to str using the to_representation method of your model serializer.

class YourSerializer(serializers.ModelSerializer):
    # other fields    

    def to_representation(self, instance):
        """ Override `to_representation` method """
        repr = super().to_representation(instance)
        repr['id'] = str(repr['id'])
        repr['quantity'] = str(repr['quantity'])    
        return repr

You can explicitly define id field in your serializer to be CharField()

Like this

class YourSerializer(serializers.ModelSerializer):
    # other fields
    id = serializers.CharField()
    
    class Meta:
        model = SomeModel
        fields = ('id', ..... other fields)

thanks, actually I had to change every field in a large table, so this method would have been a lot of work, anyways Thanks
