I'd like to make a write operation (PATCH) with an uri like /object/current.
I thought that making a Provider to load the "current" object (load it in db from info in the token) would load the db object and then the process would apply the sent data into that db obejct, but nothing seems to be working.
I tried making a processor too, but the $data passed is just the data sent in the request body, the db object is never loaded.

How can I make that kind of call ? Should I make everything manually in a processor ?
