Update map in loop

Hello

I’m new to elixir and i’m struggling with this problem

I’ve a map lets call it order and that has several products

I want to loop through this products map inside the order map and append some info from another map called associated products

it looks like this

orders map

%{
    "_csrf_token" => "gwsgw",
    "custom_tags" => "",
    "id" => "62212",
    "products" => %{
      "123456" => %{
        "category" => "3",
        "tag" => ["hero", "superstar"],
        "title" => "Product title"
      },
      "234567" => %{"category" => "5", "title" => "Product title"},
	  
      "345678" => %{
        "category" => "8",
        "tag" => ["creation", "dynasty"],
        "title" => "Product title"
      },
      "456789" => %{
        "category" => "5",
        "title" => "Product title"
      },
    },
    "order_id" => "193885",
    "custom_message" => "Nothing to declare",
    "tags_title" => %{"tag" => ["preview"]},
    "allcats" => "5"
  }

associated products map

%{
  "123456" => [
    %{
      "id" => "4984944",
      "has_stock" => false,
      "name" => "Other product Name",
      "product_id" => "123456",
     
    },
    %{
      "id" => "3511064",
      "has_stock" => true,
      "name" => "Other product Name",
      "product_id" => "123456",
     
    }
  ],
  "234567" => [
    %{
      "id" => "3511075",
      "has_stock" => true,
      "name" => "Other product Name",
      "product_id" => "234567",
     
    },
    %{
      "id" => "3511076",
      "has_stock" => false,
      "name" => "Other product Name",
      "product_id" => "234567",
     
    }
  ],
  "345678" => [
    %{
      "id" => "3511082",
      "has_stock" => true,
      "name" => "Other product Name",
      "product_id" => "345678",
     
    },
    %{
      "id" => "3511083",
      "has_stock" => false,
      "name" => "Other product Name",
      "product_id" => "345678",
     
    }
  ]

}

i tried this code to put the associated products but it only gets updated with the last item, i assume its because it doesn’t update the order in every loop

order = for {pid, v} <- order["products"] do
        IO.inspect pid
        IO.inspect v

      order = put_in(order, ["products", pid,"associated_products"], associated_products[pid])

      end

How can i achieve this result??
