I have a strong handle on when to use a helper -- at least I think so. A helper
may include some logic (not enough to belong in the model) and it presents html
as its output. So I have a conceptual problem about this solution that I've
built:
#helpers/people_helper.rb
def person_roles
(%W(assistant author collector editor foreword illustrator interviewer
introduction narrator notes translator) +
Role.group('name').map(&:name)).uniq().sort
end
I use the output in a view, as part of a collection_select picker for a
string-based attribute. This picker has a JavaScript "combobox" behavior added
to it, so the editor can add new roles to the list at whim. But the output is
an array. Does this invalidate my use of a helper method? Or am I thinking too
much about the label "helper" here?
Thanks,
Walter
