How you create new models for tabular input?

[WinterSilence]

I never using *Multiple methods before. My back-end forms communicates with Yii application through AJAX requests to REST API. API methods work with single models(composite or not).
After reading Creating a dynamic set of new records I thought: what's strange solution... why need create empty models? why not just clone prototype model?!

$setting = Setting::instance();
$setting->ensureBehaviors(); // generate behaviors
$setting-createValidators(); // and validators
$settings = [];
while (--$count > 0) {
   $settings[] = clone $setting;
}

I look at how cloning is implemented in models and was unpleasantly surprised: Model remove event handlers and Behaviors instead cloning, but other properties containing objects are ignored. Handlers/behaviours can be re-attached to cloned model without any problems.
Aslo, Model::instance() not calls ensureBehaviors(), createValidators() and return not completely initiated model.

How do you solve such problems?

Why do you prefer cloning in this case? Performance or something else?

[samdark]

OK. Makes sense.

I never had the need for it performance-wise, that's why I never solved such issue.

@samdark sounds like as unreal - any complex application have forms like this:

Not my type of applications, it seems...

@samdark you don't have applications with relations "one to many" like as item images or user roles? you kidding me :(
