SQL鍊金術會話調用不同的表

class KtOwnerAddressMaster(db.Model): 

    __tablename__ = 'kt_owner_address_master' 
    ADDRESS_ID = db.Column(Integer, primary_key=True) 
    STREET1 = db.Column(String(1024), nullable=False) 
    STREET2 = db.Column(String(1024)) 
    ZIP = db.Column(String(15)) 
    CITY_NAME = db.Column(String(200)) 
    STATE = db.Column(String(200)) 
    COUNTRY = db.Column(String(200)) 
    ADDR_EXT_ID = db.Column(String(50), nullable=False, unique=True) 
    CREATED_ON = db.Column(DateTime, nullable=False) 
    UPDATED_ON = db.Column(DateTime) 
    def __init__(self, **kwargs): 
    super(KtOwnerAddressMaster, self).__init__(**kwargs) 
    return 
class KtOwnerAddressMap(KtOwnerAddressMaster): 
    __tablename__ = 'kt_owner_address_map' 
    ADDRESS_ID =db.Column(ForeignKey(u'kt_owner_address_master.ADDRESS_ID'), primary_key=True) 
    CURRENT_ADDR = db.Column(SmallInteger, nullable=False, server_default=text("'0'")) 
    FRIENDLY_NAME = db.Column(String(100)) 
    OWNER_ID = db.Column(ForeignKey(u'kt_owner_master.OWNER_ID'), nullable=False, index=True) 

    kt_owner_master = relationship(u'KtOwnerMaster') 
    def __init__(self, **kwargs): 
    super(KtOwnerAddressMap, self).__init__(**kwargs) 
    return

在我的觀點我做以下幾點：SQL鍊金術會話調用不同的表

ad_object=KtOwnerAddressMaster(STREET1=street1, 
            STREET2=street2, 
            ZIP=zipcode, 
            ADDR_EXT_ID=addr_ext_id,       
      CREATED_ON=datetime.now().strftime("%Y:%m:%d %H:%M:%S"),        
      UPDATED_ON=datetime.now().strftime("%Y:%m:%d %H:%M:%S"), 
            CITY_NAME =city_name, 
            STATE=state, 
            COUNTRY=country) 

     db.session.add(ad_object) 
     db.session.commit() 

    addr_obj=db.session.query(KtOwnerAddressMaster).filter_by(ADDR_EXT_ID=addr_ext_id).with_entities(KtOwnerAddressMaster.ADDRESS_ID).first() 
    address_id=int(addr_obj[0])

現在我想一個地址映射添加到所有者地址映射表。

add_object=KtOwnerAddressMap(ADDRESS_ID=address_id, 
         CURRENT_ADDR="current_addr", 
         FRIENDLY_NAME="friendly_name", 
         OWNER_ID=owner_id) 

    db.session.add(add_object) 
    #The error appears on the below commit 
    db.session.commit()

我能夠看到正在填充數據庫中的地址。但我無法插入所有者來解決表中的映射問題。它給了我下面的錯誤：（_mysql_exceptions.OperationalError）（1048，「列STREET1」不能爲空「）[SQL：u'INSERT INTO kt_owner_address_master（ADDRESS_ID，STREET1，STREET2，ZIP，CITY_NAME，STATE，COUNTRY， ADDR_EXT_ID,CREATED_ON,UPDATED_ON）VALUES（％s，％s，％s，％s，％s，％s，％s，％s，％s，％s）'] [參數：（51，None，None，沒有，沒有，沒有，沒有，沒有，沒有）]

您的幫助將不勝感激。

我發現了這個缺陷。我的代碼中存在拼寫錯誤。

class KtOwnerAddressMap(KtOwnerAddressMaster):

它應該是。

class KtOwnerAddressMap(db.Model):

不知道我是怎麼做到的。現在都好！
