Nhibernate Castle活动记录无法初始化,nhibernate,castle-activerecord,Nhibernate,Castle Activerecord,我正在实施一个相对简单的用户管理模型，使用Castle Active Record，在MySql之上使用NHibernate，我遇到了一个问题。比如说，我有两个表，即下面的SQL create语句描述的用户和密码 CREATE TABLE _users ( id bigint(20) NOT NULL AUTO_INCREMENT, username char(32) NOT NULL, PRIMARY KEY (id), UNIQUE KEY username_UQ (us

我正在实施一个相对简单的用户管理模型，使用Castle Active Record，在MySql之上使用NHibernate，我遇到了一个问题。

比如说，我有两个表，即下面的SQL create语句描述的用户和密码

CREATE TABLE _users ( id bigint(20) NOT NULL AUTO_INCREMENT, username char(32) NOT NULL, PRIMARY KEY (id), UNIQUE KEY username_UQ (username), ) ENGINE=InnoDB DEFAULT CHARSET=utf8; CREATE TABLE _passwords ( id bigint(20) NOT NULL AUTO_INCREMENT, creation_date datetime NOT NULL, user_id bigint(20) NOT NULL, password_hash char(64) NOT NULL, valid_end_date datetime NOT NULL, PRIMARY KEY (id), UNIQUE KEY user_id_password_UQ (user_id,password_hash), KEY user_passwords_FK (user_id), CONSTRAINT user_passwords_FK FOREIGN KEY (user_id) REFERENCES _users (`id`) ON DELETE NO ACTION ON UPDATE NO ACTION ) ENGINE=InnoDB DEFAULT CHARSET=utf8; 最后，当此代码运行时，将生成以下异常：

Password

类的

UserId

属性，我在谷歌上搜索过，现在我完全迷路了。所以社区是我最后的希望。。。有谁能帮助我了解导致此异常的原因以及如何修复它

提前感谢您的回复和评论。

您应该有一个

用户{get；set；}

引用属性，而不是外键

这是一个很好的起点

try
{
    ActiveRecordStarter.Initialize(ActiveRecordSectionHandler.Instance, typeof(Password),
                                                                        typeof(User));
}
catch (Exception l_excpt)
{
    // handle exception
}
