除了两个表 - 教义和symfony

i have two table:

News:
id
title
body

and

NewsCopy:
id
title
body

if i add new News i would like also add this same all data for table NewsCopy?

class News extends BaseNews
{
    public function save(Doctrine_Connection $conn = null)
    {

      return parent::save($conn);
    }
}

how can i make this simply?

Well, one possible way is to hook up into the Doctrine saving mechanism:

class News{
    //..other declarations//

    //executed after Save
    public function postSave(){
        $newsCopy = new NewsCopy(); 
        //set the parameters manually
        $newsCopy->id = $this->id;
        $newsCopy->title = $this->title;
        $newsCopy->body = $this->body;

        //OR, even better, create a "cast constructor" the same idea
        //$newsCopy = new NewsCopy($this);

        $newsCopy->save();
    }
}

See "Event Listeners" chapter for more detailed explanation

The best you can do is to use triggers

You can utilize the toArray() method of the existing and populated "News" record object and populate a separate CopyNews object. With the now newly configured object you can do the save with.

I assume doctrine 1.2 - and I do not have a testing environment - so no code :).

You could probably also play with the clone() method and set a new table name ...

All untested - sorry.
