Subscribe to push for all Account calendars

[suhanoves]

Erik, thanks a lot for the great library!
Could you explain to me the moment with FolderCollection.subscribe_to_push()

My task is to subscribe to all the Account's calendars (now I have not found how to get them in less than two requests: I take account.calendar and account.calendar.children).

Perhaps the easiest way to get all subscriptions is to loop through each calendar and call subscribe_to_push method. But in this case, the number of requests is equal to the number of calendars.

I found that the FolderCollection also has a subscribe_to_push method. I thought that by calling it, I would get a tuple of subscriptions with one request, but this method returns a generator, and iterating through it I get only one subscription.

Please tell me how you see the best way to get subscriptions to all the user's calendars?

A single subscription can span multiple folders. That's the purpose of FolderCollection.subscribe_to_push() - it will create a single subscription covering all folders in the collection.

Something like FolderCollection(account=account, folders=(account.calendar,) + tuple(account.calendar.walk())).subscribe_to_push() should do what you want.

You're right that FolderCollection.subscribe_to_push() returns a generator. Looking at it again, I think that's an error. I'll have it fixed asap. For now, you can just do list(FolderCollection.subscribe_to_push())[0] since the generator should yield only one result.
