你可以像下面这样
class SpeciesSerializer(serializers.HyperlinkedModelSerializer): class meta: model = Species fields = ( 'url', 'id', 'canonical_name', 'slug', 'species', 'genus', 'subfamily', 'family', 'order','class', 'phylum', 'ncbi_id', 'ncbi_taxonomy', ) read_only_fields = ('slug',) extra_kwargs = { 'url': {'lookup_field': 'slug'} }SpeciesSerializer._declared_fields["class"] = serializers.CharField(source="class_name")
