mw.col.sched.answerCard Add-on coding problem

Development
1

I’m currently trying to write an add-on which automatically does the first review of cards added in the Add Cards dialog. I’m not the most experienced with Anki and Python, so I’m having troubles to understand why the following does not work:

mw.col.sched.answerCard(mw.col.getCard(1605091898523), 3)

Note that I just wanted to do a small test with a random card of my collection

Anki 2.1.36 (53a984ba) Python 3.8.0 Qt 5.14.2 PyQt 5.14.2
Platform: Mac 10.15.7
Flags: frz=True ao=True sv=1

Caught exception:

During handling of the above exception, another exception occurred:

Whereas mw.col.sched.answerCard(mw.col.sched.getCard(), 3) works for rescheduling the latest card in the scheduler?

This seems to be caused by the Card.timerStarted attribute not being initialized through Card.startTimer for cards obtained through mw.col.getCard, while it’s initialized for mw.col.sched.getCard as can be seen here.

Also see https://github.com/ankitects/anki/blob/f8f2839b55ec01c8796727ec5b9773e49272e9e7/pylib/anki/cards.py#L184 for the source of the error.

Looks like a bug.

I forgot to mention that you can work around this by explicitly calling startTimer before answerCard:

card = mw.col.getCard(1605091898523)
card.startTimer()
mw.col.sched.answerCard(card, 3)

Thanks, already figured that out, wasn’t able to post yet :slight_smile:

(Too excited writing the remaining code)
