Spree::ProductSet#update_attributes

A separate method of updating products was required due to an issue with the way Rails' assign_attributes and updates_attributes behave when delegated attributes of a nested
object are updated via the parent object (ie. price of variants). Updating such attributes by themselves did not work using:
product.update_attributes( { variants_attributes: [ { id: y, price: xx.x } ] } )
and so an explicit call to update attributes on each individual variant was required. ie:
variant.update_attributes( { price: xx.x } )
