I'd say that if the page uses several resources on a view, they all
belong to that controller, even if they "have the name" of a different
one. In any case, if you don't want to pollute ApplicationController
with methods to load code from other places and you need to reuse the
logic to load certain resources, write some modules and throw them in
lib. It's all just ruby, in the end :)
module ShoppingCartData
def load_addresses
@addresses = current_user.addresses.all
end
...
end
class AddressesController < ApplicationController
include ShoppingCartData
def index
load_addresses
end
end
class ShoppingCartsController < ApplicationController
include ShoppingCartData
def show
load_addresses
...
end
end
