Hi, first, thank you for your great work!

I’m wondering about something : is there any difference for getting the objects variables?
When I try to get an object variable stored in the graph, I receive a NULL value and when I use the default Grails datasource, I can get it.
For example in a simple domain class toString method:

String toString() {
“${family} ${versionNumber} (${versionName})”
}

For the rest, creating objects and browsing into the graph with the scaffold view is working, just this little problem.

Thank you in advance,
Jean-Sébastien

Sorry, this is currently not supported. But there is a complete refactoring in progress, my goal is to reuse spring-data-graph in the plugin.

I mean additional relationship types, rather than the default hasMany, belongsTo, etc.

An example could be ‘UserA isFriendsWith UserB’.

Paul,
what do you mean in detail with “own relationships”? Generally the plugin currently provides not much flexibility in terms of adopting different mapping strategies. But you could checkout the sources and make your required changes there.

Stefan

Great work with the plugin.

I’d like to add my own Relationships between nodes, e.g. User OWNS Book. How would this be done?

Thanks,

Paul.
