Partial only ever displays master variant pricing

[jhirbour]

Steps to repeat:

• Install spree 2.1
• load spree sample data
• Install this gem (2.1)

• Create examples in the admin interface (these examples from the README.md)

  Variant                Name               Range        Amount         Position
  -------------------------------------------------------------------------------
  Rails T-Shirt          1-5                (1..5)       19.99          1
  Rails T-Shirt          6-9                (6...10)     18.99          2
  Rails T-Shirt          10 or more         (10+)        17.99          3
  

• Create your own product page (copy it from the spree gem): app/views/spree/products/show.html.erb

• add the partial to you overridden product page

  <%= render :partial => 'spree/products/volume_pricing', :locals => { :product => @product } %>
  

• start your webserver
• Navigate to the product page

The problem: Strictly a display issue only: clicking the different images of the product changes the product image, but the partial only ever displays the pricing from the master.

As far as I can tell the correct price is used when you click the variant and add to your cart, but it'd be confusing for a user if you had different volume prices per variant but they are only displayed the master one.

@jhirbour I tried to parse this issue today but I couldn't. Can you show me some screenshots of what is happening? I think that would help me understand.

Setup 2 variants with volume pricing:

• Variant ID 17: http://i.imgur.com/7vPSoSk.png
• Variant ID 24: http://i.imgur.com/nMaOIog.png

• Verify in the DB

  sqlite> SELECT * FROM spree_volume_prices WHERE variant_id IN (24,17);
  id          variant_id  name        range       amount      position    created_at                  updated_at                  discount_type

  12          24          0-10        (1..10)     10          1           2014-03-26 13:24:59.834423  2014-03-26 13:24:59.834423  price

• Add the volume pricing partial: https://gist.github.com/53509634715865307ca6
• The "bulk pricing" partial never updates when you click the radio boxes (and yes I <3 Snaggit): http://i.imgur.com/b5SBWrA.png

It seems like there needs to be some javascript in this Gem like the javascript in store/product.js that re-renders the price and pictures
