Android/Java issue: realm/realm-java#1104

[fryossi]

Please include a solution for updating an existing object (delete the children before update).

@fryossi Could you be more specific, I'm not sure I understand exactly what you're asking for?

As @snowpong wrote:

If you call copyToRealmOrUpdate() on an existing root object, it will overwrite the child objects with their new data. Note: You'll have orphaned children if the updated root object no longer refers to them. For example Person "Bob" refers to two Dogs, "Fox" and "Rex". But then "Fox" dies and when you call copyToRealmOrUpdate() with a new version of "Bob" you'll still have "Fox" dangling in Realm but "Bob" no longer refers to it.

Is this feature coming anytime soon?

[bmunkholm]

@VenomVendor I would love to be able to promise that - pending a common understanding of "soon" ;-) While core already has some support for this, we also need to solve it in the context of Sync before we are ready to expose it in SDKs. There are some constraints on that front that makes it hard for us to predict timelines. But this is one of the major features that soon will be highest on the priority list. The best I can say right now is that it's not abandoned, we will get it done - it's likely in the top-5 priority list of bigger items that we hope to tackle "soon". I know that's pretty vague...Not sure if that helps you.

@bmunkholm Thanks for your explanation. We use Realm-js for a project. This feature is fifth priority in your list and expressing the order of priority does not help us much to plan. If you can provide an approximate date to add this feature.

[bmunkholm]

As we unfortunately can’t provide a timeline, I would suggest you to not depend on this feature for your project.

[pedrosimao]

I would love to see this on Realm JS.

Does embedded objects solve this?
