Question

我在带有RDS（posgreSQL）数据库的EC2实例中正在运行Airflow 1.9.0。

我在气流中使用身份验证，并且尝试通过以下步骤创建新用户：

    >>> import airflow
    >>> from airflow import models, settings
    >>> from airflow.contrib.auth.backends.password_auth import PasswordUser
    >>> user = PasswordUser(models.User())
    >>> user.username = 'new_user_name'
    >>> user.email = 'new_user_email@example.com'
    >>>  user._set_password = 'mypassword'  
    >>> session = settings.Session()
    >>> session.add(user)
    >>> session.commit()
    >>> session.close()
    >>> exit()

当我尝试执行session.commit（）时，出现了这样的错误

    Traceback (most recent call last):

    The above exception was the direct cause of the following exception:

我检查了我的RDS实例，并以此方式创建了表用户

所以我尝试将以前收到的值手动插入表中：czambrano'，'some @ email.com'，b'$ 2b $ 12 $ 1r4vhFaJHJEvOssY / EuDMuPQtN26M2crNHRjFowxYSf189P9HRkju'

但是当我尝试登录Airflow时出现错误：

某些帮助会有所帮助！

Answer 1

运行latest，以便它将创建必要的表或添加必要的列。

然后运行以下命令：（注意 upgradedb）

.encode('utf-8')

这应该解决它。
