Question

Whenever a model is created in my application, an email is sent out to several people. The response to the model creation is JS, so there is a slight delay in updating the page because first all the emails are being sent then the JS view logic kicks in (i.e. there is a noticeable lag between the time the Create button is pushed and when the page updates itself).

Is there a way I can set up my controller so that the emails are sent AFTER the view is finished updating?

Here is what my Controller action basically looks like:

def create
  @model = Model.new(params[:model])
  @model.save

  @followers.each do |f|
    ModelMailer.some_email(f).deliver
  end

  respond_to do |format|
    format.js { render :layout => false }
  end
end

You can use DelayJob or other background worker to do this and the add handle_asynchronously :deliver to your mailer.
