Data mirgration upon db version update is not working #2

Open aman-semusi opened 10 years ago

Hello,

Today came across this api and its cool. To find coredata model structure for android. I am sucessfull in building all projects and getting ToDo sample.

It running fine until I got db version updated from 3->4 where i changed some column name and added one new and remove one from old. And things worked fine, but i come across an issue of Data got lost. Where in case of iOS their is no such case.

Also i am have started working over a UI plugin for handling db-strucure in somewhat similar way we have for iOS. So my plan forth is to get a perspective ready for db modle like we have xdatamodel in iOS. We can create similar and in the UI editor we can provide a feature to create table entities and attributes. Also we can enhance it to handle Predicates too.

Thnx for helping such a realistic problem for android developer where core-data relation is to be handled manually by developers where we can maintain same in CoreData Model.

Glad to know you're finding the library useful. Yep, this is a known issue. Currently, migrations are not supported, but it's in the list of things I'd like to support soon.

I'll keep this issue open to track it.
