Problem in video uploading

hi all,
hope u r doing well. I have a problem with uploading videos in my
application. I have to upload videos in my application which will be
saved to the database. Then these videos should be displayed in
YouTube. That is user’s video should be submitted via a form in my
application to YouTube. I have already started working on this. I
found the link
I followed all the steps given in that. I have installed FFMpeg,
paperclip, state_machine. The problem i am facing with is my video is
not being saved in the database and the action is being redirected to
‘new’ instead of ‘show’.
Hope anyone of u guys would help me get out of this problem.
Thank you.
