All, While attempting to use ActiveRecord against a large database, approx. 1700 tables and 4 million rows, I discovered an inefficiency in oci_adapter.rb.

If you used MySQL FULLTEXT indexes and just upgraded to Rails 1.1, watch out for this one. Rails 1.1 now defaults to Ruby as your schema format.

All, I wasted an hour on this, so here''s a quick post to save you from the same.

The culprit is

All, This little bug caused me an hour so I thought I''d save others from it. I upgraded to Rails 1.1RC and Ruby 1.8.4RC for Windows. 90% of the app was working fine but a few RHTML templates were throwing a compile error, with parse errors and invalid chars. The culprit, tabs. Turns out Ruby 1.8.2 with Rails 1.0 didn''t care about tabs in your templates but the new

All, I have run into a road block with my RoR project.
