As a newbie to rails I can't find how to solve my issue ^^
I want to create a VideoPost from a form with a text field containing a video url (like youtube)
I'm getting information on the video thanks to the gem https://github.com/thibaudgg/video_info
And I want to save thoses information using a model of mine (VideoInformation). But I don't know how the create process should work.
Thanks for any help !

I'm trying to create a VideoPost in VideoPostsController like this :

def create
  video_info = VideoInfo.new(params[:video_url])
  video_information = VideoInformation.create(video_info)      #undefined method `stringify_keys' for #<Youtube:0x00000006a24120>
  if video_information.save
    @video_post = current_user.video_posts.build(video_information) 
  end
end

My VideoPost model :

# Table name: video_posts
#
#  id                   :integer          not null, primary key
#  user_id              :integer
#  video_information_id :integer
#  created_at           :datetime         not null
#  updated_at           :datetime         not null

My VideoInformation model (which got same attributes name than VideoInfo gem) :

# Table name: video_informations
#
#  id              :integer          not null, primary key
#  title           :string(255)
#  description     :text
#  keywords        :text
#  duration        :integer
#  video_url       :string(255)
#  thumbnail_small :string(255)
#  thumbnail_large :string(255)
#  created_at      :datetime         not null
#  updated_at      :datetime         not null
