Ooh - I'm pretty new to hobo, but I just solved this problem (visual
identification by uniquely naming something where no individual field
is unique)...
There is a "name" attribute for fields, so you can pick one field as
the name to be used (there's also rules for picking fields called
"name", "title", etc, by default):
fields do
first, :string, :name => true
second, :string
...
You can't pick two or more fields like this - you get only one field
treated as the name. Try this instead:
def name
"#{name}, #{address1}, #{city}, #{state}"
end
The method "name" will be used to calculate the value to show in
Forms, Cards and Pages. Works a treat for me. :)
I think this is the first answer I've given on this list, rather than
yet another newbie question. Feel my smugnitude (yes, I think this is
actually the right answer).
Cheers, JeremyC.
