尝试使用Yii应用数据库迁移时，我遇到了新问题。
首先我用这个创建一个新的迁移:: ./yiic migrate create tr
这给了我以下输出。
Yii Migration Tool v1.0（基于Yii v1.1.14）
创建新迁移'/var/www/html/Trackstar/protected/migrations/m130921_101251_tr.php'？ （是|否）[否]：y 新迁移成功创建。
这表明我已经创建了一个新的迁移。
现在我在up（）和down（）中添加了必要的ddl。这是它的外观。
<?php
class m130921_101251_tr extends CDbMigration {
public function up() {
//create the issue table
$this->createTable('tbl_issue', array(
'id' => 'pk',
'name' => 'string NOT NULL',
'description' => 'text',
'project_id' => 'int(11) DEFAULT NULL',
'type_id' => 'int(11) DEFAULT NULL',
'status_id' => 'int(11) DEFAULT NULL',
'owner_id' => 'int(11) DEFAULT NULL',
'requester_id' => 'int(11) DEFAULT NULL',
'create_time' => 'datetime DEFAULT NULL',
'create_user_id' => 'int(11) DEFAULT NULL',
'update_time' => 'datetime DEFAULT NULL',
'update_user_id' => 'int(11) DEFAULT NULL',
), 'ENGINE=InnoDB');
//create the user table
$this->createTable('tbl_user', array(
'id' => 'pk',
'username' => 'string NOT NULL',
'email' => 'string NOT NULL',
'password' => 'string NOT NULL',
'last_login_time' => 'datetime DEFAULT NULL',
'create_time' => 'datetime DEFAULT NULL',
'create_user_id' => 'int(11) DEFAULT NULL',
'update_time' => 'datetime DEFAULT NULL',
'update_user_id' => 'int(11) DEFAULT NULL',
), 'ENGINE=InnoDB');
//create the assignment table that allows for many-to-many
//relationship between projects and users
$this->createTable('tbl_project_user_assignment', array(
'project_id' => 'int(11) NOT NULL',
'user_id' => 'int(11) NOT NULL',
'PRIMARY KEY (`project_id`,`user_id`)',
), 'ENGINE=InnoDB');
//foreign key relationships
//the tbl_issue.project_id is a reference to tbl_project.id
$this->addForeignKey("fk_issue_project", "tbl_issue", "project_id", "tbl_project", "id", "CASCADE", "RESTRICT");
//the tbl_issue.owner_id is a reference to tbl_user.id
$this->addForeignKey("fk_issue_owner", "tbl_issue", "owner_id", "tbl_user", "id", "CASCADE", "RESTRICT");
//the tbl_issue.requester_id is a reference to tbl_user.id
$this->addForeignKey("fk_issue_requester", "tbl_issue", "requester_id", "tbl_user", "id", "CASCADE", "RESTRICT");
//the tbl_project_user_assignment.project_id is a reference to tbl_project.id
$this->addForeignKey("fk_project_user", "tbl_project_user_assignment", "project_id", "tbl_project", "id", "CASCADE", "RESTRICT");
//the tbl_project_user_assignment.user_id is a reference to tbl_ user.id
$this->addForeignKey("fk_user_project", "tbl_project_user_assignment", "user_id", "tbl_user", "id", "CASCADE", "RESTRICT");
}
public function down() {
$this->truncateTable('tbl_project_user_assignment');
$this->truncateTable('tbl_issue');
$this->truncateTable('tbl_user');
$this->dropTable('tbl_project_user_assignment');
$this->dropTable('tbl_issue');
$this->dropTable('tbl_user');
}
/*
// Use safeUp/safeDown to do migration with transaction
public function safeUp()
{
}
public function safeDown()
{
}
*/
}
现在的问题是，每当我尝试使用./yiic migrate应用此迁移时，它的失败都会出现同样的错误。这是我得到的样本输出。
[root@localhost protected]# ./yiic migrate

我似乎无法找到解决上述问题的方法。我一直在google，stackoverflow和yii论坛上搜索相关答案，但我还没找到。请提供有关如何解决此问题的任何帮助。我是Yii的新手，所以我还在学习，我很喜欢它。但陷入困境的第一步是真正的挫折。任何形式的帮助都将非常感激。
谢谢， MAXX

答案 0 :(得分：3)
编辑：您不应重命名迁移文件类，因为文件名链接到数据库中的tbl_migrations。 因此，将您的迁移文件重命名为
类<?php
class m130921_101251_tr extends CDbMigration {
EDIT2：还要确保您的文件名为protected/migrations/m130921_101251_tr.php
EDIT3：以下是Yii迁移工作原理的逻辑流程，也许这会有所帮助
Yii Migration Tool v1.0 (based on Yii v1.1.14)
到此为止意味着框架已包含在内并且您的yiic.php设置正确
Total 1 new migration to be applied:
m130921_101251_tr
这几行意味着yiic能够扫描您的迁移目录，并且还可以连接您的数据库并检查迁移文件夹中的所有文件，并查看tbl_migrations中是否存在同名的行。没有行或列为新迁移的文件
Apply the above migration? (yes|no) [no]:y
*** applying m130921_101251_tr
这行输出意味着yiic现在正在尝试应用迁移，为此它将尝试查找扩展CDbMigration框架类的相同类。如果yiic无法找到此课程，您将收到此错误。
PHP Error[2]: include(m130921_101251_tr.php): failed to open stream: No such file or directory in file /var/www/html/yii/framework/YiiBase.php at line 427
Yii的工作方式总是在PHP 5.3及以上版本中使用namspaces 查找与文件名相同的类名 来自Yii docs
命名空间类 命名空间类是指在非全局命名空间内声明的类。例如， application \ components \ GoogleMap类是在 名称空间应用\组件。使用命名空间类需要 PHP 5.3.0或更高版本。
从版本1.1.5开始，可以使用命名空间类 没有明确地包括它。例如，我们可以创建一个新的 application \ components \ GoogleMap的实例，不包括 明确对应的类文件。这是可能的 增强的Yii类自动加载机制。
我能够模拟错误的唯一情况是不使用Php 5.3或更高版本或类名与文件不匹配
答案 1 :(得分：0)
文件未正确包含在内。
include(m130921_101251_tr.php);
这就是为什么它无法找到你的班级。
尝试在 include 构造中为您的文件提供正确的路径。
