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 test
Loaded 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.
- 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. SQLite3 Version is
3.7.2-1ubuntu0.1.

Your migration failed and you have a partially migrated database in
SQLite.
I would suggest dropping and recreating your test database by hand and
then
running your tests again.

Unfortunately, that did not help. 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!
