Creating model instance does not respect "viewonly" relationship attribute

[dkellner]

I've never used viewonly myself, thanks for bringing this up. I've just tried to reproduce your problems with this (your example is incomplete, so I had to do some guesswork, e.g. you never use CommonColumns and get_current_user_id is not defined).

I've come up with https://github.com/pyeve/eve-sqlalchemy/tree/viewonly/eve_sqlalchemy/examples/viewonly and tried to POST to /nodes, which works fine and GET-ing gives created_by and organization (see below). Can you maybe amend this example to show your problems with viewonly?
