Yii遷移不起作用

Question

我的Yii遷移有問題。問題是我遷移了一個成功遷移後成功完成的代碼，我嘗試了另一個遷移代碼，但是它向我展示了遷移代碼，這是我已遷移的第一個遷移代碼，也是我需要遷移的第二個遷移代碼。我只是繼續告訴yii繼續遷移，然後給我一個錯誤，說明遷移已經完成，現在這是我已經完成的遷移，因此第二次遷移無法完成。然後，我刪除了我的第一個遷移代碼，並繼續遷移我的第二個代碼。該代碼已成功執行，但沒有創建表。有沒有人有解決方案，爲什麼我的遷移沒有完成，是我的第二個代碼，我已經執行，最後一個表是在遷移文件夾中的safeup（）和safedown（）。

這是我的代碼，但它再次向我發送錯誤。其實我是從trackstar項目學習yii。所以，這個我的代碼再次，我保持在上功能再次錯誤。你可以看看

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

以及遷移代碼粘貼起來，這是它已經開始顯示我現在的錯誤。這裏的鏈接到Dropbox的，這是它一直呈現enter link description here

我有同樣的問題的錯誤。 你應該刪除up方法。

，我發現這裏的解決方案Yii Framework - yic migrate command doesn't work

編輯：

好吧，你正在做的trackstar那麼你可以把你的代碼上（內部）和向下（）方法時，一定要保持safeUp和safeDown方法評論。 您可以將此代碼粘貼（它從同一個項目你工作）

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'); 
} 

，然後做./yiic migrate，並確保你是在保護目錄。 和一切都應該工作，我今天做到了。

希望它有幫助
