Question

Given the MVC structure below, how can I access :category? I added it to the list of attr_accessible and restarted the server, but calling p.category still doesn’t return anything. I’m sure you Rails experts will know what’s going on. Thanks in advance!

Model

class Product < ActiveRecord::Base
  belongs_to :category
  belongs_to :frame
  belongs_to :style
  belongs_to :lenses
  attr_accessible :description, :price
end

View

<% @product.each do |p| %>
<%= p.category %>
<% end %>

Controller

def sunglass
  @product = Product.all
end

Answer 1

You need to specify which column of categories table you want to display. For example, a column called name:

<% @product.each do |p| %>
 <%= p.category.name %>
<% end %>

Otherwise it will return the object… in other words, all the columns {id: 1, name: 'blabla', etc }

Also,

class Category < ActiveRecord::Base
   has_many :products
end
