ICal + google calendar

I have the same problem. The title of the calendar shows up but none of the events display on the Google calendar.

I changed Priority to critical. This is an important function to our use of the Drupal Calendar.

I have opened a bug report with Google for the Drupal ical feed events not showing the Google calendar. I hope that brings some action from somewhere.

One of the reasons we chose Drupal as a CMS is to do ical feeds to other groups and interested parties. Many said parties use Google calendar. With this bug effecting things, we are seriously hampered from doing something we need. Are there any other calendar modules around that do feeds?

Same problem here -- please help.

I'm not sure but I'll bet that Google is not handling 'VALUE=DATE-TIME'. The ical spec says both 'VALUE=DATE' and 'VALUE=DATE-TIME' are valid, but as I do more research it looks like most places are using 'VALUE=DATE', so I'm guessing that switch the code to use that instead might fix the problem. I'm doing a rewrite of the ical handling (see http://drupal.org/node/156418 and other issues) and once that's done we'll see if it fixes this problem.

Thank you, KarenS, for looking into this issue. I'd be willing to try any test code or help in some other way.

If you want to test my theory, create two files, one with the code you have above and one where you change everything that says 'VALUE=DATE-TIME' to 'VALUE=DATE'. Give them both names that end in '.ics', like old.ics and new.ics and put them on your web server.

Then try to get them into Google calendar by linking to the files you created and see if there is any difference between the way they behave.

I'll can't work on this immediately, so if you're in a hurry you can test that out and if it works, I can just make the necessary change to the code.

Tried that and it didn't work for me.

Just a bit more info, I was able to import via URL, but it didn't create any events, it just added a new empty calendar to Google.

When I tried to import the iCal file (with value=date-time OR value=date) it says "Processed zero events"

Some weeks ago I hacked the module/events/ical.inc file to do the switch from "VALUE=DATE-TIME..." to "VALUE=DATE..." as KarenS suggested. The produced ICal file had the change so I thought I did the change correctly. After waiting to check for a few days, this did not change the results. Still no events in Google Calendar. I just left my hack in place anyway.

Two days ago I follow-up emailed Google about my previous bug report to see if they had done anything. This is the response I got back:

Thank you for your reply. The calendar you provided in the previous email
doesn't contain "VALUE=DATE-TIME," instead it contains only "VALUE=DATE."
As such, it appears that Google Calendar is reading the date information
and isn't able to read the time information for your calendar. While
"VALUE=DATE" is valid, without time information, the event information
won't appear. If you're able to change the occurrences of this line to
"VALUE=DATE-TIME," you should be able to subscribe to your calendar
correctly. We appreciate your taking the time to update us on the status
of this issue.

So, I copied my backup of ical.inc into place, deleted the calendar from my Google Calendar, added it back into Google calendar and.... no events still. But I'll not declare it a failure for a couple of days to be sure Google has refreshed the feed.

That doesn't make sense, the current calendar DOES use DATE-TIME for the event dates (not for the timestamps, but I doubt they're using the timestamps anyway). I don't know what you sent them, but if you sent them what you posted at the top of this page, that answer makes no sense and solves nothing. According to that, the current code should be working.

An additional communication from Google today.

Thank you for your response.  We appreciate the additional information you've provides on this issue. We were able to successfully import your calendar by changing all instances of "VALUE=DATE" to "VALUE=DATE-TIME." This includes the "DTSTAMP" lines. Please check to see if this change allows you to successfully subscribe to your calendar. 

We appreciate your assistance as we work to resolve this issue.

The calendar feed I provided to them is http://plug.phoenix.az.us/event/ical

I have not tried nor proven this yet. When I do, I'll update things here.

Thanks for working on this, KarenS!

I had success last night!

I edited the modules/event/ical.inc file. I replaced all instances of "VALUE=DATE" with "VALUE=DATE-TIME". A couple of hours later my personal Google Calendar was displaying the events from the feed.

Caution: I did not do a code analysis or any other checking if the above described change breaks something. The correct way to fix the issue may involve something more sophisticated. Until a fix from someone who understands the code comes along, be careful with my above suggestion.

I'm going to do some other checking of the results but I think this is the right direction. What do you think, KarenS?

This is a very simple change and should not break anything else. I'm puzzled why it didn't work the other way since it was already valid according to the standards, but it won't hurt anything to do it this way.

I'm in the process of rewriting the Date and Calendar modules (the ical script is in the Date API) and I'll get that change in the new version. It's a simple enough change I can put it in the current version, too, so I just committed it.

Thanks for all the help getting this figured out!

I think the ical file should have some header information like google's does:

Hi all,

I'm playing with last calendar/date releases and I didn't see any events in google calendar.
May be it's because I still need to wait until tomorrow....

Could anybody confirm the issue is fixed?

The funny part it's that I remember it working a year or so ago.

Thanks a lot in advance, specially Karen for the great development,

m.

I replaced all instances of "VALUE=DATE" with "VALUE=DATE-TIME" in mydwupalsite/sites/all/modules/event/ical.inc

and now the events show up correctly in google calendar

Hi,
I have reactivated this bug because I can import a .ics file downloaded from my drupal site into google calendar but I can't add the same feed with the "add url" option in google calendar.

The 5.1 version and the 6.1 version are totally and completely different. No issue for 5.1 can have any applicability to 6.2. If you have a problem in 6.2, create a new issue.

So this was fixed in 5.x, I'm closing the issue.

I could not get this text file through the ical feed .. Is there any particular settings need to be done during i cal feed. could some one help me on this???
