# Part of the test security suite for the Import/Export feature
# Checks whether there are new reference attributes ending with _id in models that are currently being exported as part of the
# project Import/Export feature.
# If there are new references (foreign keys), these will have to either be replaced with actual relation
# or to be blacklisted by using the import_export.yml configuration file.
# Likewise, new models added to import_export.yml, will need to be added with their correspondent relations
# to this spec.

      It looks like #{relation_class}, which is exported using the project Import/Export, has references: #{prohibited_keys.join(',')}

      Please replace it with actual relation in IMPORT_EXPORT_CONFIG if they can be exported.

      Please denylist the attribute(s) in IMPORT_EXPORT_CONFIG by adding it to its corresponding
      model in the +excluded_attributes+ section.
