How to hide 'add to cart' button on content type full view? How to hide 'add to cart' button, on full mode view of a specific content type?
It has to be done on condition if product is purchased for this content type.

I tried to add custom field template but for add to cart button could not find the right template name. I also found out the field name which displays add to cart "field-product-ref" but the template field--field-product-ref.tpl.php is not working.
Need help in either identifying correct template name or any other approach which is correct?
You could use devel_themer module. After enable the module, a checkbox appear on left bottom of the window then, select the checkbox now you could find the template name after click the add to cart button...
