Question

I am able to create able to run my migrations from JRuby 1.6.3 and Rails 3.1rc5 and in a console session create a simple Role object like this:

jruby-1.6.3 :001 > role = Role.new(:name => "Admin")
   (1.0ms)   SELECT name
 FROM sqlite_master
 WHERE type = 'table' AND NOT name = 'sqlite_sequence'

 => #<Role id: nil, name: "Admin", created_at: nil, updated_at: nil> 

All is good but when I run

Role.destroy_all

I get the following stack trace:

jruby-1.6.3 :003 > Role.destroy_all
ArgumentError: wrong number of arguments (3 for 2)
    from /Users/paulcowan/.rvm/gems/jruby-1.6.3/gems/activerecord-3.1.0.rc5/lib/active_record/base.rb:470:in `find_by_sql'

    from script/rails:6:in `(root)'

It would seem all is not right between activerecord-3.1.0.rc5 and jruby.

Anybody any help on this?

Answer 1

You are correct. All is not right yet with activerecord-jdbc-adapter and Rails 3.1. I’m working on it and hope to have it ready by the time Rails 3.1 goes final.
