For those who want similar behaviour on before_action :authenticate_user!

  def authenticate_user!(opts = {})
    unless opts || user_signed_in? || devise_controller? || !redirectable?
      store_location_for(:user, request.fullpath)
    end
    super(opts)
  end
  
  def redirectable?
    request.get? && !request.xhr? && is_navigational_format?
  end

Great tutorial!

Is it possible to render the pdf without controller? maybe sending out via emails, or saving to s3

From the Sidekiq wiki, a Sidekiq job should be idempotent and transactional. How should we implement this?

For example, I am sending notification emails via Mandrill. How can I ensure that the email would not be sent multiple times?

Besides, is it good to wrap the jobs in ActiveRecord::Base.transaction when creating/updating/deleting database records?

Thanks!

My Rails 4 app is using Devise and Facebook OmniAuth. The web app is working perfectly. Now I want to make a iOS app to consume my rails app's API.

Instead of telling iOS users to type in their auth_token from devise-token_authenticatable gem, how can iOS app users login my Rails app after Facebook authentication?

Thanks!

In Refactoring CSV Uploads with ActiveModel::Model Download , you make a scoped class User::Import.
When should we use scoped class like this?

And, how does it different from rails generate model user/import?

Thanks!

ActionForm might suits your needs.
As the Rails team is taking over it, it would be great if @excid3 make a screencast about it.
