Logging data from the session?

Question

Ruby on Rails

There was a need to add the current user to the log. From many models, data is written to the log in the filters after_create, after_update (therefore, it will not work to transfer the session object from the controller), there is no access to the session from the model. There is an option with Thread.current[:current_user] = session[bla-bla] and this variable is available in the model, but as far as I understand, this only works for the Mongrel server, since a separate thread is created for each user - I haven’t tried it. I don’t really want to catch all the places where the creation / update takes place and write the log from the controllers (there are too many of them + you will have to add them manually in the future). Are there solutions?

Answer 1

Database callbacks after_create, after_update are best used only for working with the model itself (and the database) and not interacting with the outside world, because this is a violation of MVC. Otherwise, in my experience, there are problems worse than yours.
Even ActiveRecord::Observer is probably not worth using.
