Fixing "wrong number of arguments" Error w/Rails 1.2.3 Upgrade

Written by

in

If you’ve just upgraded your Rails gem from 1.2.2 to 1.2.3 and are getting the following error on database hits..
wrong number of arguments (1 for 0)
/opt/local/lib/ruby/gems/1.8/gems/activerecord-1.15.2/lib/active_record/vendor/mysql.rb:566:in `initialize’

..note that updating RAILS_GEM_VERSION in environment.rb appears to be required. Running a 1.2.2 application on 1.2.3 (even when 1.2.2 and all dependencies installed) will yield this error. Whatever.
