Question

I am using Propel, a PHP ORM.

I really like it.
I love to be able to write this code:

$offer->setTitle('20% off everything')->save();

But what about if I want to create a increaseImpressions method?.

Would you use it like this:

$offer->increaseImpressions()

or like this:

$offer->increaseImpressions()->save()

?

In other words, would you save the object inside or outside the increaseImpressions method?
Can you also please tell me why?

I guess this is a question about OOP.

Thanks,
Dan

Answer 1

I would suggest the the second example:

$offer->increaseImpressions()->save()

Essentially, the increaseImpressions method is just another setter. Calling save outside the increaseImpressions method keeps it consistent with the rest of the setter methods.
