Problems using ruleby with Rails 3.2.9 and Redmine 2.2.0

[Eva Schrowangen]

Hello,

I am having trouble using the ruleby gem with Redmine 2.2.0.

I included the gem in the gemfile, ran bundle install to ensure the gem is installed, and called rails s to start the server.
When I try to access the mainpage of Redmine I get a 500 server error with error message:
Token Load (0.3ms) SELECT "tokens".* FROM "tokens" WHERE "tokens"."user_id" = 1 AND (feeds) LIMIT 1
SQLite3::SQLException: no such column: feeds: SELECT "tokens".* FROM "tokens" WHERE "tokens"."user_id" = 1 AND (feeds) LIMIT 1

If I remove the ruleby gem from the gemfile, the Redmine server is accessible without problems, using the SQL statement:
Token Load (0.2ms) SELECT "tokens".* FROM "tokens" WHERE "tokens"."user_id" = 1 AND (action='feeds') LIMIT 1 (0.1ms)

So the SQL statement is different, even though the only change I made was including the ruleby gem in the gemfile.
Accessing other pages than the Redmine main page also yield even stranger syntax errors, even though no code was changed.

I am using ruby 1.8.7, Rails 3.2.9 and Redmine 2.2.0.

Is the ruleby 0.8 gem compatibel to these versions?
It was working successfully before with Rails 2.3.14 and Redmine 1.4.

I appreciate any help regarding a possible solution and information about compatibility.

Thanks in advance!

Best regards,
Eva
