Yii迁移不起作用

Question

我的Yii迁移有问题。问题是我迁移了一个成功迁移后成功完成的代码，我尝试了另一个迁移代码，但是它向我展示了迁移代码，这是我已迁移的第一个迁移代码，也是我需要迁移的第二个迁移代码。我只是继续告诉yii继续迁移，然后给我一个错误，说明迁移已经完成，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，并继续迁移我的第二个代码。该代码已成功执行，但没有创建表。有没有人有解决方案，为什么我的迁移没有完成，是我的第二个代码，我已经执行，最后一个表是在迁移文件夹中的safeup（）和safedown（）。

这是我的代码，但它再次向我发送错误。其实我是从trackstar项目学习yii。所以，这个我的代码再次，我保持在上功能再次错误。你可以看看

public function up() 
    { 
     //create the issue table 
     $this->createTable('tbl_issue', array(
       'id' => 'pk',

    public function down()

     $this->dropTable('tbl_issue'); 
     $this->dropTable('tbl_user'); 
    }

以及迁移代码粘贴起来，这是它已经开始显示我现在的错误。这里的链接到Dropbox的，这是它一直呈现enter link description here

我有同样的问题的错误。 你应该删除up方法。

，我发现这里的解决方案Yii Framework - yic migrate command doesn't work

编辑：

好吧，你正在做的trackstar那么你可以把你的代码上（内部）和向下（）方法时，一定要保持safeUp和safeDown方法评论。 您可以将此代码粘贴（它从同一个项目你工作）

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'); 
} 

，然后做./yiic migrate，并确保你是在保护目录。 和一切都应该工作，我今天做到了。

希望它有帮助
