How do I create a document in iOS CBL that is not persisted to the database until save() is called?

Hi, in my iOS app (CouchbaseLite 1.3) I sometimes want to create documents that will be discarded or not persisted. I tried using CBLModel.modelForNewDocumentInDatabase() since the method definition in the code says: /** Returns a new “untitled” CBLModel with a new unsaved document.
The document won’t be written to the database until -save is called. */

I noticed though that the documents it returns have an id field, and I can kill my app, re-start it, and then find those documents by ID in my database. How would I create a temporary document that will only get persisted when I call save()?

You can create a new CBLDocument, and even though it has an ID it doesn’t exist in the database yet. It won’t be persisted until you save it using putProperties:, update:, or by adding a new CBLRevision and saving that.

I can kill my app, re-start it, and then find those documents by ID in my database.

When a CBLDatabase is closed it saves any CBLModels that have unsaved changes, so that’s probably what you’re seeing. (On iOS this also happens when the app is suspended.)

Thanks! When you say that it saves any unsaved documents do you mean it persists them and they are in the DB forever?

Are these unsaved documents included in view indexing? Would they be included in view indexing if I kill the app and then re-open it?
