Retrieve the Active Record Association name between two classes\models

I am using Ruby on Rails 3.0.7 and I would like to know how to retrieve the Active Record Association name between two classes\models.

That 开发者_如何学JAVAis, I have two models

class User < ActiveRecord::Base
  has_many :accounts
end

class Account < ActiveRecord::Base
  belongs_to :users
end

and I would like to retrieve (on runtime) them association name, in this case accounts and users strings.

Is it possible? If so, how can I do that?

UPDATE

If I have more association statements in User and Account classes (see the below example), how can I retrieve exactly the User Account association name?

class User < ActiveRecord::Base
  has_many :accounts
  has_many :articles
  has_many :comments
end

class Account < ActiveRecord::Base
  belongs_to :users
  has_many :articles
  belongs_to :authorization
end

?

User.reflect_on_all_associations.each do |assoc|
  puts "#{assoc.macro} #{assoc.name}"
end
#=> "has_many accounts"

UPD

User.reflect_on_all_associations.select{|a| a.class_name == "Account"}.each do |assoc|
  puts "#{assoc.macro} #{assoc.name}"
end
#=> "has_many accounts"
