Normally you'd probably do something like
i.category.obj.map(_.name).openOr("unknown category!")
That is, if I have a category object give me its name, otherwise give
me "unknown category!"
Also, if you have to collect the result a bunch of possibly-failing
computations (like looking up the category can fail) then remember
that the for comprehension is your friend.
