How to pass products and quantities to ASP.NET MVC4 Web API from form submit

Hope that helps The problem is with your data serialization.
In order to be properly binded it has to be in the following format:
code :
"products" : [ 
              {"id":1, "quantity":20},
              {"id":5, "quantity":100},
              ...
             ]
 $.each(quantityElements, function (index, element) {
                var productIdElement = $(element).prevAll()[0];
                elementsToSend.push(productIdElement);
                elementsToSend.push(element);
            });
[ 
   {name:"id[1]", value:1},
   {name:"quantity[1]", value:20}
   {name:"id[2]", value:5},
   {name:"quantity[2]", value:100}
   ...
]
$.each(quantityElements, function (index, element) {
      var productIdElement = $(element).prevAll()[0];
      var product = {
           id : $(productIdElement).val(),
           quantity : $(element).val()
       };

       products.push(product);
 });
$.post(BASE_URL + "api/Order?" + $("#CustomerId").val(), products);

around this issue I have page that list the products available and I want the user to be able to indicate which quantity of each product he wants. I'm not sure what is the correct way to create the form. I have done this but I'm sure it's not the best way to do it... , Product model
code :
class Product < ApplicationRecord
  has_and_belongs_to_many :orders, join_table: PurchaseProduct.table_name

  has_many :purchase_products
end
class Order < ApplicationRecord
  has_and_belongs_to_many :products, join_table: PurchaseProduct.table_name

  has_many :purchase_products

  accepts_nested_attributes_for :purchase_products
end
class PurchaseProduct < ApplicationRecord
  belongs_to :product
  belongs_to :order
  validates :quantity, length: { minimum: 1 }
end

  ...
  <%= form.fields_for :purchase_products do |another_form| %>
    <div class="field">
      <table>
        <tr>
          <td>
            <%= another_form.label :product %>
            <%= another_form.select(:product_id, Product.all.collect {|p| [ p.name, p.id ] }, ) %>
          </td>
          <td>
            <%= another_form.label :quantity %>
            <%= another_form.number_field :quantity %>
          </td>
        </tr>
      </table>
    </div>
