Question

In my first Ruby on Rails app I’ve a one-to-many association

class Battle < ActiveRecord::Base
    has_many :rivals, :dependent => :destroy
    accepts_nested_attributes_for :rivals, :allow_destroy => true
    attr_accessible :question, :rivals_attributes
end

class Rival < ActiveRecord::Base
    belongs_to :battle
    has_attached_file :rival_image, :styles => { :normal => "300x300>", :thumb => "100x100>" }
end

Let’s say a battle has 2 rivals

<% for rival in @battle.rivals %> <%= rival.name %> <% end %> displays both rivals that belongs to battle

How do I display first rival and the second one where I need it?

Answer 1

If you want to access individual records from a association use:

<%= battle.rivals[0].name %>
