ActiveAdmin belongs_to 索引显示关联字段

Question

试图显示嵌套字段而不仅仅是 ID。 例如，product_catergory_id 不是显示外键 1，而是显示 product_catergories/product_catergory 中的 "Computers"（table/field id 1）。 f.inputs 上似乎有很多信息，但专栏上没有。

product
belongs_to :product_catergories
(has all the foreign keys)


product_catergories
has_many : products

app/admin/products.rb  --partial  

index do
    selectable_column
    #my stuff here
    column :name
    column :product_description
    column :product_catergory_id
    column :product_colour_id
    column :product_size_id
    column :supplier_id
    actions
  end
