thanks for all stackoverflow members, I learned a lot from here.
I have a question about "beforeSave", I want save the old data to history-table in the database, for example if the user change anything I want save the old informations in the history-table.
Can anyone tell me what's the "best" scenario to achieve this ?
Thank you all and all suggestions are welcome.
You must add the beforSave() function in your model.
Check if the param $insert is false theis mean you are updateing a record so
in this case you can create a new HistoryModel, polutate and save
public function beforeSave($insert)
{
if(parent::beforeSave($insert))
{
if(! $insert)
{
$historyModel = new History();
$historyModel->att1 = $this->att1;
$historyModel->att2 = $this->att2;
......
$historyModel->attN = $this->attN;
$historyModel->save();
return true;
}
}
