Question

I have 3 models: User, Order and UserOrder

user_order.rb

belongs_to :user, :class_name => "User"
belongs_to :order, :class_name => "Order"

user.rb

has_many :user_orders, foreign_key: :user_id,
                      dependent: :destroy
has_many :ordering, through: :user_orders,
                  source: :order

order.rb

has_many :reverse_user_orders, foreign_key: :order_id, 
                              dependent: :destroy,
                              class_name: "UserOrder"

has_many :orderers, through: :reverse_user_orders, source: :user

I have controller action in orders_controller.rb, which creates the relationship between user and order and it works fine (it creates the record in the database)

 def create
 ...
   if @order.save
    current_user.order!(@order)
 ....

I want to render user.name in the orders’ index.html.erb file

<%= order.orderers.name %>

but in HTML it only renders caption “User”. If I use <%= order.orderers %> it returns the full hash, including user.name.

[#<User id: 19, name: "Peter Jackson", email: "[e-mail]", remember_token:   "pj6eI2mc2_6G0UbumoEqMA", password_reset_token: nil, password_reset_sent_at: nil, created_at: "2013-01-27 14:10:15", updated_at: "2013-01-27 14:10:28", provider: nil, uid: nil, passport: nil, region: "Zimbabve"]

Any way to render user.name in orders’ index.html.erb?
Thanks

Answer 1

<%= order.orderers.first.name %> #for the first orderer.

<%= order.orderers.last.name %> #for the last orderer.

of for each orderer:

<% for o in order.orderers %>
  <%= o.name %>
 <% end %>

Regards!
