how set in controller can first video skip these validations.

def update   @video = video.find(params[:id])     if @video == @video[0]     @video.skip_video_validation = true       if @video.update_attributes(video_params)         flash[:success] = 'video updated!'         redirect_to root_url       else         render 'edit'       end     else     ...   end
