Wrestling with an error message on a Drupal Commerce site today. I kept getting errors relating to a missing template file with no path and no file name .tpl.php. Fortunatley with a little debugging giving me a pointer to the correct issue queue on Drupal the solution was readily available. So here's a few easy steps to follow in case you have the same issue.

In this post I am going to look at Drupal Commerce and demonstrate how to prepare e-commerce product data for import into Drupal Commerce - and show how to create a delimited list of product references to link the products to their display nodes. These techniques supplement the wealth of great practical demos and documentation provided by the Commerce team.

Finally solved a curious issue that has been nagging me on a test Drupal commerce site.
I have a utility script that lists products that are not linked to Product Displays (handy). Perplexingly the ‘report’ kept showing some orphaned products even though I had linked them all and the report had shown none previously.
It is a test site undergoing some heavy development so at first I put it down to that - rolling the database back and forth etc But today I noticed it and was pretty sure that nothing had changed that could cause such data changes. Could it be some bug in entity API, commerce ? Unlikely! So crack out the deer stalker and pipe lets investigate!

Below are my notes taken as I investigate techniques to achieve my Objective,

If you use the Ubercart module suite for Drupal to create e-commerce sites (we do and love it!) then one of the things you may wish to do is to change the default 'cart' to 'basket' - for a non-US audience. There is no setting in the Ubercart modules to enable this - but it is really easy and here's how to do it.
Get the excellant string overrides module and install it. Then set it up to swap the following fields:
