How to show the foriegn key value name in rails

I am working in rails 3.2.1 app.Below are my model name and their associations,

Model language_name:

class LanguageName < ActiveRecord::Base
  attr_accessible :language_name
end

language_name table:

Model news_subscription

class NewsSubscription < ActiveRecord::Base
  belongs_to :language_name
  attr_accessible :id, :user_id, :language_name_id, :subscriber_id
end

news_subscription table:

Controller:

def edit
  @news_subscription = NewsSubscription.where(:user_id => id).all
end

views

= @news_subscription.language_name_id

I want to display the language_name of language_name_id in news_subscription table. Currently When i tried with = @news_subscription.language_name_id.language it is showing "undefined method language" and @news_subscription.language_name_id showing the id alone.

I am newly learning RoR, please help me.
