interesting new app on Satchmo trunk

[Bruce Kroeze]

I've just added an interesting new application to the Satchmo trunk.  It is completely optional and backward-compatible.  Ignore it if you don't need it.

What it allows is easy product upselling/cross-selling from one page.  For example: If you were selling ebooks, you could make a checkbox on the ebook detail page allowing your customer to order the companion CD.

To use it, add "satchmo.upsell" to your INSTALLED_APPS, and run syncdb.

You'll have a new app in your admin, "upsell", which has one model "Upsell".  Upsells have "targets" and "goals".  Targets are the products you want to add upsells to.  Goals are what you are upselling.  Select them, and optionally add a description of the upsell, and select a "style" of upsell presentation.

There are five styles:
- Checkbox, qty 1, not-selected-by-default
- Checkbox, qty 1, selected-by-default
- Checkbox, qty matching the qty of the product on the page, not-selected-by-default
- Checkbox, qty matching the qty of the product on the page, selected-by-default
- or a simple form with a qty box.

The templatetag {% product_upsell product %} on product_detail templates does all the magic to handle the form.  So that way, all the user has to do is check a checkbox and they get the extra item added to their cart when they click "add to cart." I've already added it to the default store templates.

The only downside is that the goal product doesn't have any options.  It can be a be a product variation (i.e. DJ Rocks, Large, Blue), but can't be the configurable product itself.

Please let me know how it works for you.  As I said above, this should be 100% backward compatible, so ignore it if you don't want or need upselling.

I'm assuming that you did a syncdb after you added the upsell application.
