Return value based on condition in serializer
I have an Entry model in my app and when it's deleted I simply mark is as deleted instead of soft deleting (so original content stays in database). I want to implement a logic in my Serializer class that if an Entry is marked as deleted (boolean field) the field 'content' returns value "deleted" instead of the original content. I have already implemented logic that if it's deleted it cannot be changed.
I've tried using a CharField with source parameter but then it requires to be read-only so that won't work as I still want the content to be write-able.

Have you tried overriding thedataproperty? Fields are normally isolated, they don't see the whole serializer

You can use SerializerMethodField for this purpose:-
https://www.django-rest-framework.org/api-guide/fields/#serializermethodfield
class EntrySerializer(serializers.ModelSerializer):
content = serializers.SerializerMethodField()
class Meta:
model = Entry
def get_content(self, obj):
if obj.deleted:
return "Deleted"
return obj.content
