you can use serializermethodfield , need create model, in order use model serializer.

class fulltree(serializers.modelserializer):     full_tree =  serializers.serializermethodfield()      class meta:           model = fulltreemodel           fields = ('treewidth','lifephase')        get_full_tree(obj):        treewidth = obj.treewidths # treewidth        lifephase = obj.lifephases# lifephases        //build tree serializers        return your_full_tree
