如何取消引用marshmallow_mongoengine中的ReferenceFields?例如 dump_data = author_schema.dump(author).data 中的个结果 '5578726b7a58012298a5a7e2' {title='Fight Club', author=author} .

from marshmallow_mongoengine import ModelSchema

class AuthorSchema(ModelSchema):
    class Meta:
        model = Author

class BookSchema(ModelSchema):
    class Meta:
        model = Book

author_schema = AuthorSchema()

author = Author(name='Chuck Paluhniuk').save()
book = Book(title='Fight Club', author=author).save()

dump_data = author_schema.dump(author).data
# {'id': 1, 'name': 'Chuck Paluhniuk', 'books': ['5578726b7a58012298a5a7e2']}

author_schema.load(dump_data).data
# <Author(name='Chuck Paluhniuk')>

Nesting schemas

from marshmallow.fields import Nested

class AuthorSchema(ModelSchema):
    class Meta:
        model = Author        
    books = Nested("BookSchema",many=True)
