kohana - Kohana ORM - 重复的实例/数据库条目

Question

我想“复制”一个 ORM 对象，然后将其保存到数据库中（使用新的主键），但我无法取消设置复制对象的主键。

    $orm1 = new Model1($id);
    if($orm1->loaded()) {
     $orm2 = $orm1;
     $orm2->id = null; //something like this?
     unset($orm2->_primary_key); //or like this?
     $orm2->save(); //I would like to create a new entry in the db but it doesn't work
    }

我希望我足够清楚......基本上，我怎样才能在数据库中“再次保存”一个模型......？

Answer 1

You need to copy ORM data from one model to another:

// save current data
$data = $orm1->as_array();
$orm2 = new Model1();
$orm2->values($data);
$orm2->save();

This example uses separate ORM objects. You can load values back to $orm1, but don't forget to call $orm1->clear() before $orm1->values($data). This resets the model to its unloaded state.

Note that as_array will also return belongs_to relationships.

Answer 2

你可能想试试这个：

// Reset primary key
$this->_primary_key_value = NULL;
