I think I've got a reason to use a has_one model - it's basically a
table that lists some standard values for things, and a description. I
don't want to go from that table back to any other table (so a
has_many_through isn't right). Hobo doesn't support has_one
relationships... does it?
What can I do to show up this field in forms - I want to have a
selection box that shows the (small) choice of items in the "has_one"
model?
Or must I re-interpret the model, and do something to block going from
the item-description table back to the model that uses it?

Use a belongs_to relationship. Sounds like a one-to-many to me. Even though you aren't going from the direction of the many to one it still exists.

Maybe if you post the real world examples it would be easier to
decide, but Bob is probably right: it looks like you need a belongs_to
/ has_many relationship.

OK, tried this. I see what you mean. There is a relationship; I just
didn't want to expose it.
It's taken some fiddling, but I think I've now removed the way to go
from the one to the many - which was what I was really after.
Thanks for the guidance, JeremyC
