module Scenic
  # The name of a view or table according to rails.
  #
  # This removes any table name prefix or suffix that is configured via
  # ActiveRecord. This allows, for example, the SchemaDumper to dump a view with
  # its unaffixed name, consistent with how rails handles table dumping.

    # Gets the unaffixed name for the provided string
    # @return [String]
    #
    # @param name [String] The (potentially) affixed view name
