Rails activerecord has_many to has_many, query all?

Question

I'm having some trouble querying through a table, it works fine if I select only one record, but If I select multiple it doesn't work. For example

    Orders Table
      |
    / | \
OrderProducts Table
    \ | /
      |
    Products Table 

Orders model

has_many :order_products
has_many :products, :through => :order_products

OrderProducts model

belongs_to :order
belongs_to :product

Products model

has_many :order_products
has_many :orders, :through => :order_products

Activerecord queries

Order.find(1).products // this works
Order.where(type_id:1).products // this doesn't seem to work

Is it not possible to query multiple items in this manner? What would be the best way to go about querying multiple records from another table based on this structure or would I need to update my model structure? I appreciate all the help! Thanks again!

Answer 1

@orders_ids = [1, 5, 6]
Order.where(id: @orders_ids).map{|order| order.products }

it will return products for Order with id 1, 5, 6

implement this in a view:

in controller action:

@orders_ids = [1, 5, 6]
@orders = Order.where(id: @orders_ids)

in html.erb:

<% @orders.each do |order| %>
  <%= order.number %>
  <% order.products.each do |product| %>
    <%= product.name %>
  <% end %>
<% end %>
