在 marshmallow-mongoengine 中使用参考字段

Question

如何在 marshmallow_mongoengine 中取消引用 ReferenceFields？例如，dump_data = author_schema.dump(author).dataresults in'5578726b7a58012298a5a7e2'而不是更有用的 response {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')>

Answer 1

嵌套模式

from marshmallow.fields import Nested

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