fetchAll and recurring events in Android about react-native-calendar-events

[franleplant]

Thank you very much for your help and support!

Hey @franleplant, I believe that this is expected for Android when reading from the CalendarContract.Event table. I think that reading from the CalendarContract.Instances would successfully find all instances from the query. The current response should return a recurrent rule that could be used to infer future dates without a pulling every instance though.

[franleplant]

So right now I am not receiving those events from fetchAll, what is your suggestion to fix this then?

[wmcmahan]

Just to clarify, the results are all non recurring events, i.e. nothing assigned to the recurrence key such as 'daily', 'weekly', etc?

[franleplant]

Exactly, the recurrence key is always the empty string and the events are all non-recurrent. Other way of putting it is that fetchAll is not returning instances of recurrent events.

Hey @franleplant, I'm not able to reproduce this. Can you show how you are creating a recurring event and how you are fetching these events? Edit: Actually, I think I was able to reproduce by manually adding a recurring event to the calendar.

Hi! This is all the data I could gather:

This is a recurring event that happens every Wednesday (I've omitted some details for privacy reasons)

This is the code that fetches all the events for today,
tomorrow and the day past tomorrow and store them
in an array.

  const events = await Promise.all([0, 1, 2]
  // Calc the start and end of (today, tomorrow or the day after tomorrow) in the user's timezone
    .map((i) => [moment().startOf('day').add(i, "day"), moment().endOf('day').add(i, "day")])
    // Get events
    .map(([start, end]) => RNCalendarEvents.fetchAllEvents(start.toISOString(), end.toISOString())))

This is what I get from that call

The event that you see on Wednesday is other, non recurring event, that in fact comes from another calendar that I'm subscribed too, so that's working fine. The only problem is for recurring events.

I hope this helps.

A simple way of reproducing this error is by:

• create a non recurring event A today
• create a recurring event B today (potentially start it yesterday so you get a future recurring event)
• run fetchAll for today
• Only A will be present in the events Array.

Expected: A and B are returned
Actual: A is returned

Thanks @franleplant, I believe I see what the problem is. Recurring events (without an end date) cannot be found by the queries start and end date bounds. I should have a solution out for this later today. Thanks for reporting it!

Ok, i've pushed out a patch (1.3.5) for this. Hopefully this should now pull recurring events properly. Let me know if you run into any bugs. Cheers!

Glad I could help. 👍
