I have a work-around for my problem, but there's clearly something I
don't quite understand going on here and I'd like to learn.
I have a model that has a serialized field. In the unit test for that
model I'm checking the field contents. In my fixture I have
(thanks to Fred earlier for helping me get the fixtures loading
without error - needed the quotes around the yaml)
and in the test I have
assert things(:foo).items == [3,8]
and... the test fails. The problem is that things(:foo).items ends up
being an array that has a single element, the string '3 - 8'. For
longer arrays the string becomes '3 - 8 - 1 - 2 - 3', for example.
I can get around this by explicitly stating the yaml string as
manage_domains: "--- \n- 3\n- 8"
which leads to the assertion being true... but... it's inelegant, and
I don't understand why the workaround is even necessary. It would be a
lot easier to use and understand if I could get the first version
working. From a couple of tests (printing to stdout) I think .to_yaml
should be putting in the new-lines, but it seems not to be in this
Anyone care to enlighten me as to why the first version doesn't work, please?
