Question

我在rails应用程序中有一个视图，我通过Twilio API向用户显示他们最新的50个录音。

虽然返回的page_size上限为50，但API会将URI返回到返回列表的下一页，上一页，第一页和最后一页。（https://www.twilio.com/docs/api/rest/response#response-formats-list-paging-information）

我无法理解如何在该表的底部链接到这些结果，以便当用户点击“下一页”时，页面会刷新并且表格会填充接下来的50个记录。

以下是表格：

<% @recordings.list({}).each do |recording| %>

  <tr>
     <td><%= recording.sid %></td>
     <td><%= recording.duration %>sec</td>
     <td><%= recording.from %></td>
     <td><%= recording.to %></td>
 </tr>

<% end %>

<%= link_to "next page", "?" %>

当我在rails控制台中查看时，我可以在响应中看到“next_page_uri”，我只是不确定我如何“链接”它以填充表格。

编辑** 我通过他们的API资源管理器发出请求以显示输出（以JSON格式） - 我将页面结果缩短为一个请求，以便更容易阅读。

Twilio控制器 -

@account_sid = @user.twilio_account_sid
@auth_token = @user.twilio_auth_token

# set up a client to talk to the Twilio REST API
@sub_account_client = Twilio::REST::Client.new(@account_sid, @auth_token)
@subaccount = @sub_account_client.account

@recordings = @subaccount.recordings

您的网址中可以有page个参数，“下一个”按钮是指向page参数递增的当前页面的链接。然后在服务器上发出请求

"/2010-04-01/Accounts/ACb76fd7689d66a37b3defd366bc3caf12/Recordings.json?AccountSid=ACb76fd7689d66a37b3defd366bc3caf12&Page=#{param[:page]}&CSRF=1388959981-bedd066b4f6119c70465377bb8bc012a72ea7b13be683a0819b065aa9db559c7&PageSize=1&Format=json"
