Problem with :name of child

app_concerns_AssetChild.rb
module AssetChild
# by defining a module this should allow us to make nice code which adds:
#
# - has_one :assets
# - adds an after_create hook which automaticly builds the asset.
# - at some latter point we can also add after_update - to update the asset it's timestamp.
# - give access to asset attributes such as name => @usecase.name instead of @usecase.asset.name
#
