I'm testing the relation between two of my models: MessageThread (parent), which has_many Message (children). When I run the following test, it gives me an error:

Is the :condition parameter incorrect? I tried saving message, but it still didn't find the message I was looking for. Is the find method deprecated?
Neither of those objects have been saved, so there is nothing to find.
you would have to save both thread & message.

Ahhh..I have to save the thread....I see. Thank you.
OK, new problem: This time, I'm using MessageBoard (child) to acts_as_list for Forum (parent). The models looks as such:
1) Error: test_title_overlap(MessageBoardTest): ActiveRecord::StatementInvalid: Mysql::Error: #42S22Unknown column 'position' in 'order clause': SELECT * FROM message_boards WHERE (forum_id = 2) ORDER BY position DESC LIMIT 1 .... ----------------------------- Does the column name HAVE to be "position"?
No: use the :column option to acts_as_list
