question on "_removed":true

[Seung Chan Lim]

So on my iOS phonegap app I make a HTTP request to my server.

On my server I make a change on a document using python (I actually make an HTTP request to the SGW to do this, even though I'm on the server. That way I take advantage of the async HTTP api instead of the synchronous api provided by Python)

After making the change on the server I get a change notification on my iOS Phonegap app saying that particular document now has a "_removed" : true set on it.

Can someone help me understand why this is?

This means the document is no longer accessible to the client because it's no longer in any channels the client has access to. The document seen by the client now has no properties except "_removed":true, and the client won't get any further updates.

As a side note, when I look at the doc directly using the Web interface for couchbase server, I don't see such attribute set. All looks fine. So it's only on the phonegap iOS side that the doc somehow has become removed.

Ah... Then do I have to assign the doc to a channel every time I make changes to it?

Yes, but that should happen automatically. The sync function will be called for every change made to the document, and gets to decide what channels it's in. In other words, the document's channels are determined by its content.

Does the same hold true for (access) or can (access) be called just once?

It's all the same. Every time the document is updated the sync function recomputes all of its attributes.
