I have an error I don''t know how to debug. I am adding the login suport in Depot (the example in the RoR book) and LoginController#add_user throws ActiveRecord::StatementInvalid in an innocent /login/add_user GET request. The trace goes down to a call to SQLiteAdapter#table_structure, and the source code suggests what''s happening is that "PRAGMA table_structure(#{table_name})" is returning empty metadata for some reason: def table_structure(table_name) returning structure = execute("PRAGMA table_info(# {table_name})") do...

Hi everyone. I can''t get the above(subject line) combination to work. If I use a standard sqlite3 file db for the test db, and spec_server all the specs on my models pass. If I use an in-memory db for the test db, script/spec w/o spec_server, they all pass. But if I use in-memory and spec_server I get the following error: 1) ActiveRecord::StatementInvalid in ''User should be

Hello, I get this error trying to load some data from DB. I''m using Rails 1.2.2 on Fedora Core 6 and Sybase adapter. This worked fine when application run under Rails 1.1.6 but now I''m migrating to 1.2.2 and have some problems. At browser I got: SQL Command for table_structure for tplib_bckps failed Message: schema_info not found. Specify owner.objectname or use sp_help to check whether the object exists (sp_help may produce lots of output). And in the log file: Setting row count to (0) SQL Command failed! ** SybSQLContext Server Message: ** Message number 208 Sever...

I still want to get this into Rails for all connection adaptors, but for now I''ve hacked my own addition on for just PostgreSQL. The following code extends every Column object returned by MyModel.columns to support a new #required? method, which indicates if the column may or may not be null. The following is a huge hack - suggestions on a cleaner way to add this functionality
