I have a number of models that use an aggregation to combine First Name,
Middle Initial and Last Name and they have been working fine. I am
looking to clean this up, DRY it if possible.
I have things like this in application.rb
class Clwholename
attr_reader :first_name, :middle_initial, :last_name
def initialize(first_name, middle_initial, last_name)
@first_name = first_name
@middle_initial = middle_initial
@last_name = last_name
end
def to_s
[ @first_name, @middle_initial, @last_name ].compact.join(" ")
end
end
and then in whichever model I need to use this, I have…
composed_of :clwholename,
:class_name => Clwholename,
:mapping =>
[[ :first_name, :first_name ],
[ :middle_initial, :middle_initial ],
[ :last_name, :last_name ]
]
which is repeated in a number of models. I ran into a snag when trying
to use RAV (which is very cool but gags on my Clwholename class if I
include models) and the suggestion was to put the stuff in
lib/clwholename.rb and ‘require’ it in my model.
I seem to be working fine by putting the class definition for
Clwholename in lib/clwholename.rb and requiring it in my model but the
section of “composed of :clwholename” simply doesn’t work if I put it
into helpers (I assume because that is for views and not controllers) or
in the lib/clwholename (unknown method composed_of) and I am not getting
any DRYer.
What’s the best way to handle this?
