Stock Counts

3:10 with Jason Seifer

In this video, we begin to implement our inventory stock counts.

Code Samples

We set up a couple of helper methods in our Inventoryable class to keep up with stock counts:

module Inventoryable

  def stock_count
    @stock_count ||= 0
  end

  def stock_count=(number)
    @stock_count = number
  end

  def in_stock?
    stock_count > 0
  end

end

    So let's go ahead and first off we're just going to include it 0:00
    in the shirt class, and that'll be a good start. 0:05
    So now, let's go ahead and make a couple of attribute methods for 0:11
    setting the stock status of an item. 0:16
    So we want to be able to say, okay this is how many 0:19
    units are in stock for a shirt, a pair of pants, an accessory, whatever. 0:25
