Fixture columns of Oracle LOBs type do not get loaded

Discovered in Rails version: revision 4606

When you are using functional tests fixtures with Rails, if you are using Oracle 10g with oci8 adapter, and if your fixture's column type in the database is of type CLOB or BLOB, chances are your fixtures for that column will NOT get loaded.

For example:

$ cat customers.yml
simple_customer:
  id: 1
  some_text: A whole bunch of text.

Then your customers(:simple_customer).some_text is nil.

Workaround:

In your functional test setup method,

customers(:simple_customer).some_text = 'A whole bunch of text."
customers(:simple_customer).save

before each of your test methods start using simple_customer.
