# Note:
#
# The UI allows the enabled attributes only via the project_custom_field_project_mappings.
# The API still provides the old behaviour where all the custom fields are available regardless
# of the enabled mapping. Once the api behaviour is aligned to the UI behaviour, this method
# can be removed in favour of the available_custom_fields.
# As a future improvement a flag `via_api=true` can be set on the project when the
# modification happens via the api, then set the available_custom_fields accordingly. This allows
# the extension to be completely removed from the acts_as_customizable plugin.
