Yii迁移不起作用

我的Yii迁移存在问题。问题是我迁移了一个代码，这个代码在成功迁移后成功完成，我尝试了另一个迁移代码，但这向我展示了迁移代码，我已经迁移的第一个代码，以及我需要迁移的第二个代码。我继续告诉yii继续迁移，之后向我发送了一个错误，表明迁移已经完成，现在这是我已经完成的迁移，因此第二次迁移无法完成。然后我删除了我的第一个迁移代码，然后继续迁移我的第二个代码。代码已成功执行但没有创建表。有没有人有这方面的解决方案，为什么我的迁移没有完成，是我执行的第二个代码，最后一个表在safeup（）和safedown（）在迁移文件夹中。

这是我的代码，但它再次向我发送错误。实际上我正在从trackstar项目中学习yii。所以，这是我的代码，我再次将它保留在up函数错误中。你能看看吗

    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_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 totbl_project.id
        $this->addForeignKey("fk_project_user", "tbl_project_user_

                "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');
    }

很好地粘贴了迁移代码，这是它现在开始向我显示的错误。这里是Dropbox的链接，这是它显示的错误enter link description here

我有同样的问题。 你应该删除up方法。

我在这里找到了解决方案Yii Framework - yic migrate command doesn't work

修改

好的，你正在使用trackstar然后你可以将你的代码放在up（）和down（）方法中，确保保持safeUp和safeDown方法的注释。 您可以粘贴此代码（来自您正在处理的同一项目）

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');
}

然后执行./yiic migrate并确保您位于受保护的目录中。 一切都应该有效，我今天就这样做了。

希望有所帮助
