What should I use instead of 'repeat' method in newest version?

Hi,

I've been working on my own flashcard app. Until today, I was using py-fsrs 3.1, but I wanted to implement the Optimizer, so I updated to the latest version.

Previously, I was using the following code to get the intervals for each rating, so I could display them above the buttons—similar to how it's done in Anki:

    def calculate_interval_for_all_qualities(self):
        fsrs_card = self.to_fsrs_card()
        review_time = timezone.now()
        scheduling_cards = self.fsrs.repeat(fsrs_card, review_time)

        return [
            self.format_interval(scheduling_cards[Rating.Again].card.due - review_time),
            self.format_interval(scheduling_cards[Rating.Hard].card.due - review_time),
            self.format_interval(scheduling_cards[Rating.Good].card.due - review_time),
            self.format_interval(scheduling_cards[Rating.Easy].card.due - review_time)
        ]

However, it seems that the FSRS class has been replaced by Scheduler, and the repeat method is no longer available. How can I achieve the same effect in the latest version?

Thanks!

We replaced the repeat method with the review_card method in version 4.0.0. You can view the release notes here. Furthermore, I'd recommend skimming the Quickstart in the README so see an example of how to use the review_card method.

But, for your case specifically, I believe you'd just call review_card four times - once for each rating to compute your intervals.

Am I good to "Mark as answer"?
