How to delete data from NV storage?

[kapso]

Is there a way to delete data from NV storage after I have saved using Model.serialize_to_file

Looked around inside the code and the docs, cant find this info anywhere?

Your app's data is deleted when your user removes the app. If you want to, you can remove the files using Ruby's File class methods on the persistent store.

Well I have a "logout" functionality which once clicked should remove the data from storage. Can you point me to the code where I can find the file path details?

In the README here you can see that persistence to the sandbox is done by filename. When your user logs out, you can adopt one of several strategies:

• Delete the data objects relevant to that user and then persist the object collection -or-
• Delete all the data objects and then persist the object collection -or-
• Use Ruby's File#delete to simply remove the file. Note this does not tell MotionModel that you are deleting the persistent data so you could re-serialize the in-memory version after removing the file and it would be as though you didn't delete it.

I recommend you remove the data using MotionModel's delete_all or destroy_all methods, then either serialize the model to persist the empty changes to the non-volatile store or you could use File#delete.

I wrote a straw man that I think would solve your problem: https://github.com/sxross/MotionModel/wiki/Strategy-for-MotionModel-Persistence
