Recently I wrote an authentication controller, and it worked on RAILS 0.8. I didn''t work on the site for a few weeks, though, and now my authentication controller fails when used with the latest version of Rails and ActiveRecord, both the latest stable versions and the 12-01 beta gems. Here is the error I receive: ActiveRecord::StatementInvalid in Authentication#signup unable to open database file: BEGIN /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.1.0.200412010045/lib/active_record/connection_adapters/abstract_adapter.rb:342:in `log'' /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.1.0.200412010045/lib/active_record/connection_adapters/sqlite_adapter.rb:50:in `execute'' /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.1.0.200412010045/lib/active_record/connection_adapters/sqlite_adapter.rb:67:in `begin_db_transaction'' /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.1.0.200412010045/lib/active_record/connection_adapters/abstract_adapter.rb:284:in `transaction'' /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.1.0.200412010045/lib/active_record/transactions.rb:86:in `transaction'' /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.1.0.200412010045/lib/active_record/transactions.rb:100:in `transaction'' /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.1.0.200412010045/lib/active_record/transactions.rb:115:in `save'' /home/nolan/whatssofunny/publicapp/controllers/authentication_controller.rb:27:in `signup'' /usr/local/lib/ruby/gems/1.8/gems/actionpack-0.9.5.200412010045/lib/action_controller/base.rb:592:in `send'' /usr/local/lib/ruby/gems/1.8/gems/actionpack-0.9.5.200412010045/lib/action_controller/base.rb:592:in `perform_action_without_filters'' /usr/local/lib/ruby/gems/1.8/gems/actionpack-0.9.5.200412010045/lib/action_controller/filters.rb:236:in `perform_action_without_benchmark'' /usr/local/lib/ruby/gems/1.8/gems/actionpack-0.9.5.200412010045/lib/action_controller/benchmarking.rb:30:in `perform_action_without_rescue'' /usr/local/lib/ruby/gems/1.8/gems/actionpack-0.9.5.200412010045/lib/action_controller/benchmarking.rb:30:in `measure'' /usr/local/lib/ruby/gems/1.8/gems/actionpack-0.9.5.200412010045/lib/action_controller/benchmarking.rb:30:in `perform_action_without_rescue'' /usr/local/lib/ruby/gems/1.8/gems/actionpack-0.9.5.200412010045/lib/action_controller/rescue.rb:68:in `perform_action'' /usr/local/lib/ruby/gems/1.8/gems/actionpack-0.9.5.200412010045/lib/action_controller/base.rb:276:in `process'' /usr/local/lib/ruby/gems/1.8/gems/actionpack-0.9.5.200412010045/lib/action_controller/base.rb:249:in `process'' /usr/local/lib/ruby/gems/1.8/gems/rails-0.8.5.200412010045/lib/dispatcher.rb:37:in `dispatch'' AuthenticationController:27 is a call to Member.save. I''m sure the configuration is right and that I''m pointing at a valid database because immediately before I received this error I got a "Trying to write to read-only database," which went away when I fixed the permissions on the file. Any thoughts on what might be going on? What additional information can I offer to help track this down?
