[Rails] Re: find_or_create : how to know the resulting operation ?
Just a thought. Maybe you can use a call back before the record is saved to set up a virtual attribute based on the result of new_record?

Thank you for your answers, I like the solution with the 'initialize' function but I still haven't tried it. I have a counter which counts the number of new occurence I will insert in the database, that's why I want to be able to distinguish both cases, Sincerely, Fabrice -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.

I strongly suspect that there is a better way to accomplish what you're trying to do -- perhaps having the count done on the DB side would be useful.

With find_or_create, I don't believe there is a way. You can certainly do it with find_or_initialize winter = Tag.find_or_initialize_by_name(Winter) winter.persisted? # true if record exists, false if it does not -- You received this message because you are subscribed to the Google Groups Ruby on Rails: Talk group.
