How can I set a hook on relations?  
I need to do sth after adding/linking a relation record.  
I found `addHook` for collections but I couldn’t find anything which does the same for relations.

Hey @bond

`addHook` should work in your case if you set the hook the on targeted relation model.

You could also use `replaceFieldWriting` but we highly suggest to rely on hooks for those kind of feature.

Again, if you could share a use-case (either here or via DM if you consider it private), maybe we can be a bit more specific on how to implement such use-case.
