我正在尝试使用棉花糖sqlalchemy创建API
但是,当我转储数据时,它仅显示父模型数据
like {'id':1,'date':'2019-09-01'}
如何获取类似{'id':1,'date':'2019-09-01','orders':{'id':1,'date':'2019-09-01 '},{'id':1,'date':'2019-09-01'}}
模型是
class Order(db.Model):
id = db.Column(db.Integer, primary_key=True, autoincrement=True)
company_id = db.Column(db.Integer, db.ForeignKey('user_company.id'), nullable=False)
company = db.relationship('UserCompany', backref='orders', lazy=True)
date = db.Column(db.DateTime(), server_default=func.now())
class UserCompany(db.Model):
id = db.Column(db.Integer, primary_key=True, autoincrement=True)
company_name = db.Column(db.String(length=20))
架构是
class OrderSchema(ModelSchema):
class Meta:
sqla_session = db.Session
fields = ('id', 'date')
model = Order
order_schema = OrderSchema()
orders_schema = OrderSchema(many=True)
class UserCompanySchema(ModelSchema):
orders = Nested(OrderSchema, many=True)
class Meta:
fields = ('id', 'company_name')
model = UserCompany
sqla_session = db.session
user_company_schema = UserCompanySchema()
视图是
company = UserCompany.query.get(current_user.company.id)
print(user_company_schema.dump(company))
{'id': 1, 'date': '2019-09-01'}
我想要的是
{'id': 1, 'date': '2019-09-01', 'orders': {'id': 1, 'date': '2019-09-01'}, {'id': 1, 'date': '2019-09-01'}}
答案 0 :(得分:1)
如果希望它们出现在转储中,则需要在Meta类中显式设置所有期望的字段。
class UserCompanySchema(ModelSchema):
orders = Nested(OrderSchema, many=True)
class Meta:
fields = ('id', 'company_name', 'orders')
model = UserCompany
sqla_session = db.session
