Rails Youtube_it gem background job - ruby-on-rails

Question

I'm fairly new to Rails and I have a Ruby on Rails 3.2 application and I've integrated the Youtube_it gem seen here https://github.com/kylejginavan/youtube_it. The gem works fine and I'm able to upload the video to youtube, but it takes a while to process the video. I would like to be able to run that as a background job and redirect the user to the thank you page I have created.
I'm not sure where to call the delay method. I would like to call the delay method and then have the user redirect to the page_path('thank-you') page.
Any help would be greatly appreciated. I've searched all over for an answer.
VideosController
def upload
#video = Video.create(params[:video])
if #video
#upload_info = Video.delay.token_form(params[:video], save_video_new_video_url(video_id: #video.id))
else
respond_to do |format|
format.html { render "/videos/new" }
end
end
end
def save_video
#video = Video.find(params[:video_id])
if params[:status].to_i == 200
#video.update_attributes(youtube_id: params[:id].to_s, is_complete: true, user_id: current_user.id, approved: false)
Video.delete_incomplete_videos
else
Video.delete_video(#video)
end
#redirect_to videos_path, notice: "video successfully uploaded"
redirect_to page_path('thank-you')
end
Here is my controller.
class VideosController < ApplicationController
before_filter :authenticate_user!, only: [:new, :upload, :save_video, :destroy]
def index
if params[:category]
Video.yt_session
#videos = Video.approved.where(category_id: params[:category])
else
Video.yt_session
#videos = Video.approved
end
respond_to do |format|
format.html # index.html.erb
format.json { render json: #videos }
end
end
def show
#video = Video.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.json { render json: #video }
end
end
def new
#video =Video.new
#categories = Category.all
respond_to do |format|
format.html # new.html.erb
format.json { render json: #video }
end
end
def upload
#video = Video.create(params[:video])
if #video
#upload_info = Video.token_form(params[:video], save_video_new_video_url(video_id: #video.id))
else
respond_to do |format|
format.html { render "/videos/new" }
end
end
end
def save_video
#video = Video.find(params[:video_id])
respond_to do |format|
if #video.update_attributes(:youtube_id => params[:id].to_s, :is_complete => true,:user_id=>current_user.id,:approved=>false)
format.html { redirect_to page_path('thank-you') }
format.json { head :no_content }
else
format.html { Video.delete_video(#video) }
format.json { render json: #category.errors, status: :unprocessable_entity }
end
end
end
def destroy
#video = Video.find(params[:id])
if Video.delete_video(#video)
flash[:notice] = "Video deleted."
else
flash[:error] = "We were unable to delete this video."
end
redirect_to videos_path
end
def vote_up
#video = Video.find(params[:id])
#video.update_attribute(:votes_up, (#video.votes_up.to_i + 1))
redirect_to #video
end
protected
def collection
#videos ||= end_of_association_chain.completes
end
end

You can always use background workers to do that using the like of delayed_job, but personally speaking I prefer to use Resque/beanstalkd/RabbitMQ since I can run multiple workers, concurrently.
To make your life even easier, you just try Sidekiq (https://github.com/mperham/sidekiq).
You will move your worker logic to some worker.
Include Sidekiq to your Gemfile
gem 'sidekiq'
At your controller add something like:
VideoSaverWorker.perform_async(#video.id)
The VideoSaverWorker must look something like:
class VideoSaverWorker
include Sidekiq::Worker
sidekiq_options queue: "high"
def perform(video_id)
video = Video.find(video_id)
.....
.....
end
end
Please note using this you will do the work at a background thread, but it wont redirect you to the related page.
You will need to do some workarounds, something like periodically refrishing the page till you see the changes at your view html page, or maybe you can push the changes to your webpage using Faye or Node.js.
