ruby-on-rails json spree httparty solidus

Rails loop through inserted variable from database to url for external call

I'm trying to show the line_items of an order from Solidus into the Items table in my rails app. Previously I saved the orders from Solidus to my "Order" (in my app) table with attribute "order_number"

I need to insert the order_number into the url I'm using for the external call using httparty and loop through all the rows in order_number to show the attributes of each order in my index view. Each order, for example: http://localhost:4000/api/orders/R984044507.json?token=fd5a8b4b294303ad52fcb19a9eaf8bb7325d20a8aa5abbc7 has a structure like this:

here is my controller:

# items controller      
     def index
          order_number = 'R984044507' # just to test until I figure out how to loop through order_ids
          url = 'http://localhost:4000/api/orders/'
          key = '.json?token=fd5a8b4b294303ad52fcb19a9eaf8bb7325d20a8aa5abbc7'
          response = HTTParty.get(url+order_number+key)

          @items = response.parsed_response    
      end

My Index looks like this:

<table>
  <thead>
    <tr>
      <th>Order</th>
      <th>Variand_Id</th>
      <th>Product</th>
      <th>Price</th>
      <th>Qty</th>
      <th colspan="3"></th>
    </tr>
  </thead>

  <tbody>

    <% (@items['line_items']).each do |item| %>
      <tr>
        <td><%= @items['number'] %></td>
        <td><%= item['variant']["id"] %></td>
        <td><%= item['variant']["name"] %></td>
        <td><%= item['variant']['price'] %></td>
        <td><%= item["quantity"] %></td>

      </tr>
    <% end %>
  </tbody>

</table>

I hard coded the order number of one of the orders in my Orders table to test that it shows the items in each order, but I don't know how to loop through the orders so I get the items from every order.

I'm not sure my approach is the best, I'm a beginner. Any help will be appreciated.

Solution

You could do something like this:

Controller

def index
  orders = Order.all.pluck(:number)

  @items = []
  orders.each do |order|
    order_number = order
    url = 'http://localhost:4000/api/orders/'
    key = '.json?token=fd5a8b4b294303ad52fcb19a9eaf8bb7325d20a8aa5abbc7'
    response = HTTParty.get(url+order_number+key)

    @items << response.parsed_response
  end
end

First you get all order numbers (i assume that number is the column name in orders table) and then you loop through them, requesting each order and adding its attributes to @items array.

View

<table>
  <thead>
    <tr>
      <th>Order</th>
      <th>Variand_Id</th>
      <th>Product</th>
      <th>Price</th>
      <th>Qty</th>
      <th colspan="3"></th>
    </tr>
  </thead>

  <tbody>
    <% @items.each do |item| %>
      <% item['line_items'].each do |line_item| %>
        <tr>
          <td><%= item['number'] %></td>
          <td><%= line_item['variant']["id"] %></td>
          <td><%= line_item['variant']["name"] %></td>
          <td><%= line_item['variant']['price'] %></td>
          <td><%= line_item["quantity"] %></td>
        </tr>
      <% end %>
    <% end %>
  </tbody>
</table>

Since @items is an array you will need to iterate it too, so two loops are needed: one for @items and one for line_items.

Although this solution should work, note that requesting a high number of orders could cause performance issues.
