Question

我有以下课程：

class Identity(Base):
"Identity model."

__tablename__ = 'identity'

id = Column('ID_IDENTITY', Integer, Sequence('identity_seq'), primary_key=True, nullable=False)
uuid = Column('DS_UUID', String(32), ForeignKey('customer.NX_UUID'), nullable=False)
type = Column('DS_TYPE', String(255), nullable=False)
value = Column('DS_VALUE', String(255), nullable=False)

和

class Customer(Base):
"Customer model."

__tablename__ = 'customer'

uuid = Column('NX_UUID', String(32), primary_key=True, nullable=False)
name = Column('DS_NICK_NAME', String(255), nullable=False)

identities = relationship(Identity, backref=backref('custome', cascade='all', uselist=True), lazy='dynamic')

我想发布一个新客户传递一个契约列表，我试图通过跟随json这样做：

{"name":"Teste", uuid: "12121212121","identities":[{"type":"cpf","value":"05882110955"}, {"CNPJ":"0123456656"}, {"RG":"AAA3243"}]}

但是我收到了错误：

 unhashable type: 'dict'

要做到这一点的任何想法吗？

您需要创建标识SQLAlchemy模型对象，如下所示：

cust = Customer(name="Test", uuid="12121212121")
id1 = Identity(type="cpf", value="05882110955", uuid="asdasda")
id2 = Identity(type="CNPJ", value="0123456656", uuid="sdzxc3")

cust.identites = [id1, id2]
db_session.add(cust)
db_session.commit()

SqlAlchemy烧瓶级联保存json
