Accessing rails attributes through deep associations

Accessing rails attributes through deep associations

Here are my relevant models:
class ListItem < ActiveRecord::Base
belongs_to :inventory_item
belongs_to :shopping_list
belongs_to :item
end
class ShoppingList < ActiveRecord::Base
has_many :list_items
belongs_to :user, :foreign_key => :user_id
end
class InventoryItem < ActiveRecord::Base
belongs_to :item, :foreign_key => :item_id
belongs_to :vendor
has_many :list_items
end
I'm trying to access attributes of InventoryItem in my view. Here's what I
currently have in my ShoppingListController.
def show
@list_items = ShoppingList.find(params[:id]).list_items
end
Can I do something like @inventory_items = @list_items.inventory_items?
That code and variants of it that I've tried haven't worked. What am i
missing here? Any tips for accessing attributes through multiple models
like this? Thanks in advance!
