Rails - Aug 2007 - ArgumentError: interning empty string and enum-column plugin

Hello,

   I am a developer who has just started working on a large scale
website in a team of 5 other developers.    One of the developers has
introduced some enum columns into the the database.   Now, by default,
active record doesn''t support enum column types but I have added the
enum-column plugin into our project.   This has worked very well except
for a few instances where he introduced enums that featured and empty
string IE.
enum('''',''Artist'',''Venue'',''Fan'',''Label'').

This causes the mysql_adapter.rb section of the plugin to throw a
"ArgumentError: interning empty string" error in this section of code:

[code]
class MysqlColumnWithEnum < MysqlColumn
      include ActiveRecordEnumerations::Column

      def initialize(name, default, sql_type = nil, null = true)
        if sql_type =~ /^enum/i

          values = sql_type.sub(/^enum\(''([^)]+)''\)/i,
''\1'').split("'',''").map { |v|
v.intern}

          default = default.intern if default and !default.empty?
        end
        super(name, default, sql_type, null, values)
      end
    end
  end
[/code]

Does anyone know how I can work around this error?

Thanks for your time!
