#add_properties(prop) ⇒ Object

Add properties to the current product. For every property (or set of properties) an inventory-object is created (unless an inventory-object for the property (or set of properties) already exists).

DEPRECATED !!!!!

set products-association for object (virtual attributes) used for product-create/edit-view saves the product first, due to “unsaved associations” error

end

#set_properties2=(p) ⇒ Object

set property associations for the current product p can either be a hash or an array of properties.

p = [ PropertyA, PropertyB]
p = [ [ PropertyA, PropertyB], [ PropertyA, PropertyC] ]

p = { "Size" => { "1" => 1 },
      "Color" => { "32" => 1 } }

for each property (or set of properties) an invenvory-object is created and associated with the properties.

inventoy-objects which are currently associated with the product and do not match the properties (p) are deleted.

used in the admin-views, to update the product-property associations.
