everyone, Just out of curiosity, I did a dtrace -n ''syscall:::entry { @num[execname, probefunc] = count(); }'' and looked at the entries produced by ''rm''.

Is there anyway to refer to the entities being linked in a foreign key field of a fixture by name instead of id? Ie, if I have categories.yml some_cat: id: 1 name: Foo other_cat: id: 2 name: Bar data.yml some_item: id: 1 category_id: <%= categories(:some_cat).id %> name: Hello World The above doesn''t work due to scope, even if the fixtures are loaded in the proper order.

I must admit I''m really having a hard time writing the very first example(s) for a fresh standalone Ruby project. I haven''t really got a clue where to

Hi all, I have an array of shipping_type''s being returned, and I want to see what is in there. In the past I have done: shipping_type.include?(Cart::SHIPPING_TYPE_REGULAR).should be_true This works, but looks really ugly.. It just doesn''t roll of the tongue very well. I then looked up the use of Predicates, which I had been using, but hadn''t realized:
