CakePHP 1.3：如何遷移到我的文章Tabel - 功能

我有一個應用程序使用另一個php cms系統，我現在將其轉移到CakePHP 1.3。我已經到了一個地步，我需要將我的舊文章tblnewsarticles轉移到我的新CakePHP表articles。這些表格有不同的字段，但我已經能夠將我需要的所有字段映射到新表格。我在我的ArticlesController class中創建了以下臨時migrate函數來爲我執行此操作，但不能將數據保存到我的表中。一切似乎都沒有問題，包括我已經完成了debug($data)和debug($articles)的測試，它顯示了數據，但我無法保存任何內容。我看不出什麼毛病此所以任何幫助表示讚賞...CakePHP 1.3：如何遷移到我的文章Tabel - 功能

//TEMPORARY FUNCTION THAT WILL BE DELETED/DEACTIVATED AFTER MIGRATION 
function migrate(){     
     // FOR TESTING PURPOSES I SET LIMIT=1, BUT I HAVE OVER 4000 ARTICLES TO TRANSFER 
    $articles = $this->Article->query(
     "SELECT articleID,subcategoryID,article_title,article_html,article_date,image_extension FROM tblnewsarticles LIMIT 1;" 
    ); 

    foreach($articles as $article){ 
     $data['Article']['id'] = $article['tblnewsarticles']['articleID']; 
     $data['Article']['published'] = 1; 
     $data['Article']['title'] = $article['tblnewsarticles']['article_title']; 
     $data['Article']['body'] = $article['tblnewsarticles']['article_html']; 
     $data['Article']['main_image'] = 'cat_'.$article['tblnewsarticles']['subcategoryID'].'/'.$article['tblnewsarticles']['articleID'].'.'.$article['tblnewsarticles']['image_extension']; 
     $data['Article']['category_id'] = $article['tblnewsarticles']['subcategoryID']; 
     $data['Article']['user_id'] = 2; 
     $data['Article']['created'] = $article['tblnewsarticles']['article_date']; 

     if (!empty($data)) { 
      $this->Article->create(); 
      $this->Article->save($data);      
      $this->Session->setFlash('Migration processed successfully'); 
     }else{      
      $this->Session->setFlash('Unsuccessful'); 
     } 
    } 
}

========這就是我這樣做，工作對我來說========== ======

function migrateArticle(){ 

$articles = $this->Article->query(
        "SELECT articleID,subcategoryID,article_title,article_html,article_date,image_extension FROM tblnewscategories;" 
    ); 

    foreach($articles as $article){ 

    $categoryID = $article['tblnewsarticles']['subcategoryID']; 
    $articleID = $article['tblnewsarticles']['articleID']; 
    $articleTitle = $article['tblnewsarticles']['article_title']; 
    $articleSlug = str_replace(" ","-",strtolower($articleTitle)); 
    $articleBody = $article['tblnewsarticles']['article_html']; 
    $articleImage = 'cat_'.$article['tblnewsarticles']['subcategoryID'].'/'.$article['tblnewsarticles']['articleID'].'.'.$article['tblnewsarticles']['image_extension']; 
    $articleDate = $article['tblnewsarticles']['article_date']; 

    $this->Article->query("INSERT INTO categories (id, published, title, slug, body, main_image, category_id, user_id, created) VALUES('$articleID', '1', '$articleTitle', '$articleSlug', '$articleBody', '$articleImage', '$categoryID', '2', '$articleDate');"); 
    } 
}

爲什麼不這樣做在數據庫級別？它可能會少得多的代碼。 – 2012-01-17 21:15:37

數據庫級別？對不起，但你是什麼意思？ – 2012-01-17 22:11:15

明白了..謝謝 – 2012-01-18 01:34:44

不要試圖加載4000條記錄全部一次，然後分別處理它們。使用單個數據庫查詢來複制所有內容可能更容易。像

INSERT INTO articles 
    (id, published, title, body, 
    main_image, 
    category_id, user_id, created) 
    SELECT articleID, 1, article_title, article_html, 
      CONCAT('cat_', subcategoryID, '/', articleID, '.', image_extension), 
      subcategoryID, 2, article_date 
    FROM tblnewsarticles;

（未經測試，當然）東西
