(from [1f3525b1add3be8bb659cddec35542c34ff30c82]) Temporary fix for saving/updating related nodes for depth > 2 for Neo4j::Rails::Model [#211]
I want to create more rspecs before I close this.
I guess that there might be problem update properties on the new nodes in a rails callback as well.

Thanks for the tmp workaround.
But unfortunately (as you pointed out) I must remove the validation which I do need to have.
For now I'll disable it in my app and fail specs with the hope you'll be able to fix it soon.
Cheers.

I've added a couple more specs where one is failing. https://github.com/andreasronge/neo4j/pull/88
Clearly there's an issue with validations.

- State changed from “new” to “resolved”
(from [52f67f812806057b821d01d7ee1fb6277aae5c3d]) Made unpersisted relationships available in callbacks [#211 state:resolved]
Notice, if you add relationship to a model in a callback then the callback will be called twice.

I will investigate and see if it's possible to avoid callbacks being called more then twice

Done some more investigation.
The callbacks are called once except when call the constructor like this:company = Company.create(:primary_user => u1) # will generate to callbacks to validateI guess the user tries to validate all its related relationships, and the company does the same.
It's a different bug -
