# 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 } )
|
|
#
