[Python] Flask Post api not returning created object data as response

I am writing flask sample application in which i have following model and schemas. PlainStore schema is as following

class PlainStoreSchema(Schema):
id = fields.Str(dump_only=True)
name = fields.Str(required=True)


Item schema is like

class ItemSchema(PlainItemSchema):
store_id = fields.Int(required=True)
store_name = fields.Nested(PlainStoreSchema(), dump_only=True)


Store schema is

class StoreSchema(Schema):
# store_id = fields.Int(dump_only=True)
items = fields.List(fields.Nested(PlainItemSchema()), dump_only=True)


I am writing a post api endpoint which will accept just a name as parameter and create a store but response to that i need to return is id and name of store.Below if the code for endpoint

@blp.route("/store")


class StoreList(MethodView): @blp.response(200, StoreSchema(many=True)) def get(self): return StoreModel.query.all()

@blp.arguments(PlainStoreSchema)
@blp.response(201, StoreSchema)
def post(self, store_data):
try:
store = StoreModel(**store_data)
db.session.add(store)
db.session.commit()
except IntegrityError:
abort(400, message="Store already exists")
except SQLAlchemyError as e:
abort(500, message="Error occurred while saving store data")
return store, 201


Store model is

class StoreModel(db.Model):
__tablename__ = "store"

id = db.Column(db.Integer, primary_key=True, unique=True)
name = db.Column(db.String(100), nullable=False, unique=True)
items = db.relationship("ItemModel", back_populates="store", lazy="dynamic")

def __repr__(self):
return f"<StoreModel id={self.id} name={self.name}>"


With all this code when i try to hit post api with name parameter i get only following in response

{
"items": []}


I tried referred this Python Flask post and return json objects but here they are manually trying to return json response.
