我在棉花糖中有这些模式:
class Parents(Schema):
father = fields.String(data_key="father")
mother = fields.String(data_key="mother")
class UserSchema(Schema):
user_id = fields.Integer(data_key="userID")
name = fields.String(data_key="nameUser")
parents = Nested(Parents, many=True)
“father”和“mother”与“user_id”和“name”在同一个表中,但“parents”只是JSON的一个属性:
{
"data": [
{
"userID": 1,
"nameUser": "Guido",
"parents": {
"father": "John",
"mother": "Marie"
}
}
...
]
}
我用“嵌套”类尝试过,但它不起作用。那么当模型中不存在“parents”属性时如何进行嵌套呢?
