I am new to rails. I found Ruby On Rails to be very interesting. I studied
all the basics.
I have developed multiple file upload using paperclip successfully, but when
i tried the same application using 2.3.4 it is giving many errors.
Did you remember to do rake rails:update when you went to 2.3.4?
I would be thankful to you if you can guide me on multiple file upload from
scratch.
Why do you need to do it from scratch if you have it working with
paperclip and just need to move to a later rails. Which version were
you using successfully?
