RemoveAll example not working

[deontologician]

Your second example is right. Alternately, if you want to check the responses of the removeAll:

messages.findAll({ from: 'bob' }, {from: 'agatha' }).fetch()
  .map(messageList => messages.removeAll(messageList))
  .subscribe({
    next(removedId) { console.log(`id ${removedId} was removed`) },
    error(err) { console.error(`Error removing items! ${err}`) },
    complete() { console.log('All items removed successfully') },
  })

@deontologician Would it fix the example at http://horizon.io/api/collection/#removeall to add a .toArray() here?

var messageList = messages.findAll({from: "bob"}, {from: "agatha"}).fetch().toArray();

[deontologician]

No, .toArray() still returns an observable, instead of getting [{id:1}, ...] you'd get [[{id:1}, ...]] since it's already emitting an array. In this case there's no way around a callback like @rnenjoy does with .subscribe, or by chaining operations like in my example. It's fundamentally an asynchronous operation, and the example is written in a style that requires the results to be available synchronously

[danielmewes]

Ah right, makes sense. So what you wrote here #79 (comment) is probably what we should put into the docs?

[deontologician]

Yeah, it's effectively the same as @rnenjoy's example, but is more general since it shows how to get the removed ids back out
