OK. I have 4 models, item/category/subcategory/brand association like following item belongs_to :brands belongs_to :categories belongs_to :subcategories brand has_many :items category has_many :items has_many :subcategories subcategory has_many :items belongs_to :category I also have "category_id", "brand_id", "subcategory_id" as integer, in @items I have following in item/index view <% for item in @items %> <%=h item.category.category_name %> <%=h item.brand.brand_name %> I got undefined method "category" error message, but no error message for "brand" In rails console, I tried like following >> c=Item.find(:first) >> c.brand.brand_name above I can got the brand_name correctly. But >> c.category.category_name I got same error message "undefined method 'category' " Why would this happen?

Hi Fred, Sorry that's my fault. in my code actually it's singular. Because "brand" part works fine :-) item belongs_to :brand belongs_to :category belongs_to :subcategory
