## call to enqueue, doesn't even write on redis

  def create
    if @portfolio = current_user.create_portfolio( params[ :portfolio ] )
      Resque.enqueue( PortfolioGenerator, current_user.subdomain )
      redirect_to root_path
    else
      render :new
    end
  end

## calling Job directly, this one works as expected


  def create
    if @portfolio = current_user.create_portfolio( params[ :portfolio ] )
      Resque::Job.create( :portfolio_generation, PortfolioGenerator, current_user.subdomain  )
      redirect_to root_path
    else
      render :new
    end
  end

## Job

module PortfolioGenerator

  @queue = 'portfolio_generation'

  def self.perform subdomain
    puts subdomain
  end

end

Quick thing to help clarify: debug and step into line 5

leshill, sorry for the fuss, you can close the issue.
The problem is that resque_spec was included by mistake in dev env and not only in test, and it obviously didn't work.
Sorry for wasting your time.
