Hi Brett,

Try this: Build the feed URL for the calendar of interest and use the CalendarService.getFeed() to retrieve it. Then use the BaseFeed.getCanPost() API [1] to check to see if it's possible to post new entries to it with the same authentication context as was used to retrieve the feed.

Cheers!

thanks ryan, i was using the wrong URL...

Is there a way to find the access level of another persons calendar. For example, i have created a web application which allows you to add events into other peoples calendars. The user decides which calendar to add into by choosing an option from a drop down menu. The drop down menu is populated with all the people who this user has access to. The application finds the email address associated with the chosen calendar, and this is how events are added into it:

URL feedUrl = new URL("http://www.google.com/calendar/ feeds/"+selectedCalendarEmailAddress+"/private/full");

//Code to construct an event and insert it etc...

So imagine Luke Jones gives me read-only permission to his calendar. How can I check my access level to his calendar before I try adding an event into it?

thanks

Brett

Hi Brett,

Well - that was just an example. If you already used the entry variable name, you could use something else. In this case, 'entry' should represent a CalendarEntry from the calendar meta-feed (notice the example method retrieves /calendar/feeds/default rather than something like /calendar/feeds/default/private/full).

Have you taken a look at the full method posted? This retrieves the meta feed and looks through each calendar and prints out the title and access level.

Hi Ryan thanks for your reply, however i'm still having some problems:

entry.getTitle().getPlainText()); is returning the title of the last event inserted entry.getAccessLevel().getValue()); is causing a NullPointerException

does the entry.getAccessLevel refer to the calendar or an individual entry within the calendar?

i'm creating a web application using AuthSub login, if that makes any difference?

thanks

BTW-- to access this information in the Java Client lib, you can do: entry.getAccessLevel().getValue())

Here's a modified version of the sample/calendar/ CalendarClient::printUserCalendars method that outputs the accesslevel as well.

/** * Prints a list of all the user's calendars. * * @param service An authenticated CalendarService object. * @throws Exception If an error occurs during feed retrieval. */ private static void printUserCalendars(CalendarService service) throws Exception { URL feedUrl = new URL("http://www.google.com/calendar/feeds/ default");

new CalendarFeed().declareExtensions(service.getExtensionProfile());

// Send the request and receive the response: CalendarFeed resultFeed = service.getFeed(feedUrl, CalendarFeed.class);

System.out.println("Your calendars:"); System.out.println(); for (int i = 0; i < resultFeed.getEntries().size(); i++) { CalendarEntry entry = resultFeed.getEntries().get(i); System.out.println("\t" + entry.getTitle().getPlainText()); System.out.println("\t" + entry.getAccessLevel().getValue()); } System.out.println(); }

Cheers,

Yes, there is a <gCal:accesslevel...> element in the calendar meta- feed (when authenticated):

http://www.google.com/calendar/feeds/default

The documentation on gCal::accesslevel is at:

http://code.google.com/apis/calendar/reference.html#gcal_reference

Note, there is also an additional access level which is called 'root'. This is held by a domain admin of Google Apps for all calendars on their domain. It has the same privileges as 'manager'. Also, note, 'contributor' should be 'editor'. These bugs have been filed against our documentation.

is there an API call which will allow me to check the permission I have on a certain calendar?

I want to know if a calendar is read-only before i try and insert an event into it, via the API.

Thanks
