Hi! I''ve got a very strange problem. Suddenly the SQLite3 Backend stopped working. Example 1:> rake db:rollback== CreateProducts: reverting ================================================-- drop_table(:products) rake aborted! An error has occurred, this and all later migrations canceled: SQLite3::SQLException: near "CASCADE": syntax error: DROP TABLE "products" CASCADE I googled for this error message, but didn''t find anything useful. BTW, there is nothing special in the migration script: class CreateProducts < ActiveRecord::Migration # ... def self.down drop_table :products end end Example 2:> rake testLoaded suite /home/vlad/.rvm/gems/ruby-1.9.2-p136/gems/rake-0.8.7/lib/rake/rake_test_loader Started E Finished in 0.046598 seconds. 1) Error: test_product_attributes_must_not_be_empty(ProductTest): SystemStackError: stack level too deep /home/vlad/.rvm/gems/ruby-1.9.2-p136/gems/rails_sql_views-0.8.0/lib/rails_sql_views/connection_adapters/abstract_adapter.rb:23 1 tests, 0 assertions, 0 failures, 1 errors, 0 skips It doesn''t matter, what is in the test. Any test will fail, even if I just write ''assert true'' there. Those problems disappear if I change to another backend, for example MySQL. Any Ideas? P.S. My OS is Ubuntu Linux 10.10 with latest Updates.

I deleted the database and recreated it (BTW, this is a really simple test project with just one relation), but I still get the same error. I still cannot do rake db:rollback in the development environment. This is the output with --trace: ** Invoke db:rollback (first_time) ** Invoke environment (first_time) ** Execute environment ** Execute db:rollback == CreateProducts: reverting ================================================-- drop_table(:products) rake aborted!
