Observe collection changes made only by other clients

help
1

Hi,
Is there a way to get notified when collection is changed by other client? I don’t want to catch the event made by the current client.

The closest thing I can find is to use collection.observeChanges(), but the bigger problem is that

  1. the “added” is triggered for every doc when the query first run, I basicly
    need to observe the changes after the local collection has been
    initialized.

  2. I only want to identify the external changes(add/modify/remove), I don’t even want to know the detail delta, only let me know “the current query is outdated by other clients”.

    observeHandle = Collenction.find().observeChanges({
    // only want to monitor the added event from external source
    added: function (id, fields) {
    console.log(“observeChanges added”);
    }
    });

What should I do to solve this problem?

Thank you!

I have the same requirement. Keen to hear how people are solving this.

My req: I have notification documents, which i want to animate temporarily on receipt by the client.

You could persist the connection id on the document and filter by that. If you don’t want them clogging up your db, you could do clean ups afterwards.

And regarding your point 1, use a simple initializing flag to filter out the initial data load (see last code sample of this section).
